   Thanks @jgopel, @alexezeder and @DanielaE.
 
-# 7.1.3 - 2020-11-24
-
-- Fixed handling of buffer boundaries in `format_to_n`
-  (https://github.com/fmtlib/fmt/issues/1996,
-  https://github.com/fmtlib/fmt/issues/2029).
-- Fixed linkage errors when linking with a shared library
-  (https://github.com/fmtlib/fmt/issues/2011).
-- Reintroduced ostream support to range formatters
-  (https://github.com/fmtlib/fmt/issues/2014).
-- Worked around an issue with mixing std versions in gcc
-  (https://github.com/fmtlib/fmt/issues/2017).
-
-# 7.1.2 - 2020-11-04
-
-- Fixed floating point formatting with large precision
-  (https://github.com/fmtlib/fmt/issues/1976).
-
-# 7.1.1 - 2020-11-01
-
-- Fixed ABI compatibility with 7.0.x
-  (https://github.com/fmtlib/fmt/issues/1961).
-- Added the `FMT_ARM_ABI_COMPATIBILITY` macro to work around ABI
-  incompatibility between GCC and Clang on ARM
-  (https://github.com/fmtlib/fmt/issues/1919).
-- Worked around a SFINAE bug in GCC 8
-  (https://github.com/fmtlib/fmt/issues/1957).
-- Fixed linkage errors when building with GCC\'s LTO
-  (https://github.com/fmtlib/fmt/issues/1955).
-- Fixed a compilation error when building without `__builtin_clz` or
-  equivalent (https://github.com/fmtlib/fmt/pull/1968).
-  Thanks @tohammer.
-- Fixed a sign conversion warning
-  (https://github.com/fmtlib/fmt/pull/1964). Thanks @OptoCloud.
-
-# 7.1.0 - 2020-10-25
-
-- Switched from
-  [Grisu3](https://www.cs.tufts.edu/~nr/cs257/archive/florian-loitsch/printf.pdf)
-  to [Dragonbox](https://github.com/jk-jeon/dragonbox) for the default
-  floating-point formatting which gives the shortest decimal
-  representation with round-trip guarantee and correct rounding
-  (https://github.com/fmtlib/fmt/pull/1882,
-  https://github.com/fmtlib/fmt/pull/1887,
-  https://github.com/fmtlib/fmt/pull/1894). This makes {fmt}
-  up to 20-30x faster than common implementations of
-  `std::ostringstream` and `sprintf` on
-  [dtoa-benchmark](https://github.com/fmtlib/dtoa-benchmark) and
-  faster than double-conversion and Ryū:
-
-  ![](https://user-images.githubusercontent.com/576385/95684665-11719600-0ba8-11eb-8e5b-972ff4e49428.png)
-
-  It is possible to get even better performance at the cost of larger
-  binary size by compiling with the `FMT_USE_FULL_CACHE_DRAGONBOX`
-  macro set to 1.
-
-  Thanks @jk-jeon.
-
-- Added an experimental unsynchronized file output API which, together
-  with [format string
-  compilation](https://fmt.dev/latest/api.html#compile-api), can give
-  [5-9 times speed up compared to
-  fprintf](https://www.zverovich.net/2020/08/04/optimal-file-buffer-size.html)
-  on common platforms ([godbolt](https://godbolt.org/z/nsTcG8)):
-
-  ```c++
-  #include <fmt/os.h>
-
-  int main() {
-    auto f = fmt::output_file("guide");
-    f.print("The answer is {}.", 42);
-  }
-  ```
-
-- Added a formatter for `std::chrono::time_point<system_clock>`
-  (https://github.com/fmtlib/fmt/issues/1819,
-  https://github.com/fmtlib/fmt/pull/1837). For example
-  ([godbolt](https://godbolt.org/z/c4M6fh)):
-
-  ```c++
-  #include <fmt/chrono.h>
-
-  int main() {
-    auto now = std::chrono::system_clock::now();
-    fmt::print("The time is {:%H:%M:%S}.\n", now);
-  }
-  ```
-
-  Thanks @adamburgess.
-
-- Added support for ranges with non-const `begin`/`end` to `fmt::join`
-  (https://github.com/fmtlib/fmt/issues/1784,
-  https://github.com/fmtlib/fmt/pull/1786). For example
-  ([godbolt](https://godbolt.org/z/jP63Tv)):
-
-  ```c++
-  #include <fmt/ranges.h>
-  #include <range/v3/view/filter.hpp>
-
-  int main() {
-    using std::literals::string_literals::operator""s;
-    auto strs = std::array{"a"s, "bb"s, "ccc"s};
-    auto range = strs | ranges::views::filter(
-      [] (const std::string &x) { return x.size() != 2; }
-    );
-    fmt::print("{}\n", fmt::join(range, ""));
-  }
-  ```
-
-  prints \"accc\".
-
-  Thanks @tonyelewis.
-
-- Added a `memory_buffer::append` overload that takes a range
-  (https://github.com/fmtlib/fmt/pull/1806). Thanks @BRevzin.
-
-- Improved handling of single code units in `FMT_COMPILE`. For
-  example:
-
-  ```c++
-  #include <fmt/compile.h>
-
-  char* f(char* buf) {
-    return fmt::format_to(buf, FMT_COMPILE("x{}"), 42);
-  }
-  ```
-
-  compiles to just ([godbolt](https://godbolt.org/z/5vncz3)):
-
-  ```asm
-  _Z1fPc:
-    movb $120, (%rdi)
-    xorl %edx, %edx
-    cmpl $42, _ZN3fmt2v76detail10basic_dataIvE23zero_or_powers_of_10_32E+8(%rip)
-    movl $3, %eax
-    seta %dl
-    subl %edx, %eax
-    movzwl _ZN3fmt2v76detail10basic_dataIvE6digitsE+84(%rip), %edx
-    cltq
-    addq %rdi, %rax
-    movw %dx, -2(%rax)
-    ret
-  ```
-
-  Here a single `mov` instruction writes `'x'` (`$120`) to the output
-  buffer.
-
-- Added dynamic width support to format string compilation
-  (https://github.com/fmtlib/fmt/issues/1809).
-
-- Improved error reporting for unformattable types: now you\'ll get
-  the type name directly in the error message instead of the note:
-
-  ```c++
-  #include <fmt/core.h>
-
-  struct how_about_no {};
-
-  int main() {
-    fmt::print("{}", how_about_no());
-  }
-  ```
-
-  Error ([godbolt](https://godbolt.org/z/GoxM4e)):
-
-  `fmt/core.h:1438:3: error: static_assert failed due to requirement 'fmt::v7::formattable<how_about_no>()' "Cannot format an argument. To make type T formattable provide a formatter<T> specialization: https://fmt.dev/latest/api.html#udt" ...`
-
-- Added the
-  [make_args_checked](https://fmt.dev/7.1.0/api.html#argument-lists)
-  function template that allows you to write formatting functions with
-  compile-time format string checks and avoid binary code bloat
-  ([godbolt](https://godbolt.org/z/PEf9qr)):
-
-  ```c++
-  void vlog(const char* file, int line, fmt::string_view format,
-            fmt::format_args args) {
-    fmt::print("{}: {}: ", file, line);
-    fmt::vprint(format, args);
-  }
-
-  template <typename S, typename... Args>
-  void log(const char* file, int line, const S& format, Args&&... args) {
-    vlog(file, line, format,
-        fmt::make_args_checked<Args...>(format, args...));
-  }
-
-  #define MY_LOG(format, ...) \
-    log(__FILE__, __LINE__, FMT_STRING(format), __VA_ARGS__)
-
-  MY_LOG("invalid squishiness: {}", 42);
-  ```
-
-- Replaced `snprintf` fallback with a faster internal IEEE 754 `float`
-  and `double` formatter for arbitrary precision. For example
-  ([godbolt](https://godbolt.org/z/dPhWvj)):
-
-  ```c++
-  #include <fmt/core.h>
-
-  int main() {
-    fmt::print("{:.500}\n", 4.9406564584124654E-324);
-  }
-  ```
-
-  prints
-
-  `4.9406564584124654417656879286822137236505980261432476442558568250067550727020875186529983636163599237979656469544571773092665671035593979639877479601078187812630071319031140452784581716784898210368871863605699873072305000638740915356498438731247339727316961514003171538539807412623856559117102665855668676818703956031062493194527159149245532930545654440112748012970999954193198940908041656332452475714786901472678015935523861155013480352649347201937902681071074917033322268447533357208324319360923829e-324`.
-
-- Made `format_to_n` and `formatted_size` part of the [core
-  API](https://fmt.dev/latest/api.html#core-api)
-  ([godbolt](https://godbolt.org/z/sPjY1K)):
-
-  ```c++
-  #include <fmt/core.h>
-
-  int main() {
-    char buffer[10];
-    auto result = fmt::format_to_n(buffer, sizeof(buffer), "{}", 42);
-  }
-  ```
-
-- Added `fmt::format_to_n` overload with format string compilation
-  (https://github.com/fmtlib/fmt/issues/1764,
-  https://github.com/fmtlib/fmt/pull/1767,
-  https://github.com/fmtlib/fmt/pull/1869). For example
-  ([godbolt](https://godbolt.org/z/93h86q)):
-
-  ```c++
-  #include <fmt/compile.h>
-
-  int main() {
-    char buffer[8];
-    fmt::format_to_n(buffer, sizeof(buffer), FMT_COMPILE("{}"), 42);
-  }
-  ```
-
-  Thanks @Kurkin and @alexezeder.
-
-- Added `fmt::format_to` overload that take `text_style`
-  (https://github.com/fmtlib/fmt/issues/1593,
-  https://github.com/fmtlib/fmt/issues/1842,
-  https://github.com/fmtlib/fmt/pull/1843). For example
-  ([godbolt](https://godbolt.org/z/91153r)):
-
-  ```c++
-  #include <fmt/color.h>
-
-  int main() {
-    std::string out;
-    fmt::format_to(std::back_inserter(out),
-                   fmt::emphasis::bold | fg(fmt::color::red),
-                   "The answer is {}.", 42);
-  }
-  ```
-
-  Thanks @Naios.
-
-- Made the `'#'` specifier emit trailing zeros in addition to the
-  decimal point (https://github.com/fmtlib/fmt/issues/1797).
-  For example ([godbolt](https://godbolt.org/z/bhdcW9)):
-
-  ```c++
-  #include <fmt/core.h>
-
-  int main() {
-    fmt::print("{:#.2g}", 0.5);
-  }
-  ```
-
-  prints `0.50`.
-
-- Changed the default floating point format to not include `.0` for
-  consistency with `std::format` and `std::to_chars`
-  (https://github.com/fmtlib/fmt/issues/1893,
-  https://github.com/fmtlib/fmt/issues/1943). It is possible
-  to get the decimal point and trailing zero with the `#` specifier.
-
-- Fixed an issue with floating-point formatting that could result in
-  addition of a non-significant trailing zero in rare cases e.g.
-  `1.00e-34` instead of `1.0e-34`
-  (https://github.com/fmtlib/fmt/issues/1873,
-  https://github.com/fmtlib/fmt/issues/1917).
-
-- Made `fmt::to_string` fallback on `ostream` insertion operator if
-  the `formatter` specialization is not provided
-  (https://github.com/fmtlib/fmt/issues/1815,
-  https://github.com/fmtlib/fmt/pull/1829). Thanks @alexezeder.
-
-- Added support for the append mode to the experimental file API and
-  improved `fcntl.h` detection.
-  (https://github.com/fmtlib/fmt/pull/1847,
-  https://github.com/fmtlib/fmt/pull/1848). Thanks @t-wiser.
-
-- Fixed handling of types that have both an implicit conversion
-  operator and an overloaded `ostream` insertion operator
-  (https://github.com/fmtlib/fmt/issues/1766).
-
-- Fixed a slicing issue in an internal iterator type
-  (https://github.com/fmtlib/fmt/pull/1822). Thanks @BRevzin.
-
-- Fixed an issue in locale-specific integer formatting
-  (https://github.com/fmtlib/fmt/issues/1927).
-
-- Fixed handling of exotic code unit types
-  (https://github.com/fmtlib/fmt/issues/1870,
-  https://github.com/fmtlib/fmt/issues/1932).
-
-- Improved `FMT_ALWAYS_INLINE`
-  (https://github.com/fmtlib/fmt/pull/1878). Thanks @jk-jeon.
-
-- Removed dependency on `windows.h`
-  (https://github.com/fmtlib/fmt/pull/1900). Thanks @bernd5.
-
-- Optimized counting of decimal digits on MSVC
-  (https://github.com/fmtlib/fmt/pull/1890). Thanks @mwinterb.
-
-- Improved documentation
-  (https://github.com/fmtlib/fmt/issues/1772,
-  https://github.com/fmtlib/fmt/pull/1775,
-  https://github.com/fmtlib/fmt/pull/1792,
-  https://github.com/fmtlib/fmt/pull/1838,
-  https://github.com/fmtlib/fmt/pull/1888,
-  https://github.com/fmtlib/fmt/pull/1918,
-  https://github.com/fmtlib/fmt/pull/1939).
-  Thanks @leolchat, @pepsiman, @Klaim, @ravijanjam, @francesco-st and @udnaan.
-
-- Added the `FMT_REDUCE_INT_INSTANTIATIONS` CMake option that reduces
-  the binary code size at the cost of some integer formatting
-  performance. This can be useful for extremely memory-constrained
-  embedded systems
-  (https://github.com/fmtlib/fmt/issues/1778,
-  https://github.com/fmtlib/fmt/pull/1781). Thanks @kammce.
-
-- Added the `FMT_USE_INLINE_NAMESPACES` macro to control usage of
-  inline namespaces
-  (https://github.com/fmtlib/fmt/pull/1945). Thanks @darklukee.
-
-- Improved build configuration
-  (https://github.com/fmtlib/fmt/pull/1760,
-  https://github.com/fmtlib/fmt/pull/1770,
-  https://github.com/fmtlib/fmt/issues/1779,
-  https://github.com/fmtlib/fmt/pull/1783,
-  https://github.com/fmtlib/fmt/pull/1823).
-  Thanks @dvetutnev, @xvitaly, @tambry, @medithe and @martinwuehrer.
-
-- Fixed various warnings and compilation issues
-  (https://github.com/fmtlib/fmt/pull/1790,

-# 7.0.3 - 2020-08-06
-
-- Worked around broken `numeric_limits` for 128-bit integers
-  (https://github.com/fmtlib/fmt/issues/1787).
-- Added error reporting on missing named arguments
-  (https://github.com/fmtlib/fmt/issues/1796).
-- Stopped using 128-bit integers with clang-cl
-  (https://github.com/fmtlib/fmt/pull/1800). Thanks @Kingcom.
-- Fixed issues in locale-specific integer formatting
-  (https://github.com/fmtlib/fmt/issues/1782,
-  https://github.com/fmtlib/fmt/issues/1801).
-
-# 7.0.2 - 2020-07-29
-
-- Worked around broken `numeric_limits` for 128-bit integers
-  (https://github.com/fmtlib/fmt/issues/1725).
-- Fixed compatibility with CMake 3.4
-  (https://github.com/fmtlib/fmt/issues/1779).
-- Fixed handling of digit separators in locale-specific formatting
-  (https://github.com/fmtlib/fmt/issues/1782).
-
-# 7.0.1 - 2020-07-07
-
-- Updated the inline version namespace name.
-- Worked around a gcc bug in mangling of alias templates
-  (https://github.com/fmtlib/fmt/issues/1753).
-- Fixed a linkage error on Windows
-  (https://github.com/fmtlib/fmt/issues/1757). Thanks @Kurkin.
-- Fixed minor issues with the documentation.
-
-# 7.0.0 - 2020-07-05
-
-- Reduced the library size. For example, on macOS a stripped test
-  binary statically linked with {fmt} [shrank from \~368k to less than
-  100k](http://www.zverovich.net/2020/05/21/reducing-library-size.html).
-
-- Added a simpler and more efficient [format string compilation
-  API](https://fmt.dev/7.0.0/api.html#compile-api):
-
-  ```c++
-  #include <fmt/compile.h>
-
-  // Converts 42 into std::string using the most efficient method and no
-  // runtime format string processing.
-  std::string s = fmt::format(FMT_COMPILE("{}"), 42);
-  ```
-
-  The old `fmt::compile` API is now deprecated.
-
-- Optimized integer formatting: `format_to` with format string
-  compilation and a stack-allocated buffer is now [faster than
-  to_chars on both libc++ and
-  libstdc++](http://www.zverovich.net/2020/06/13/fast-int-to-string-revisited.html).
-
-- Optimized handling of small format strings. For example,
-
-  ```c++
-  fmt::format("Result: {}: ({},{},{},{})", str1, str2, str3, str4, str5)
-  ```
-
-  is now \~40% faster
-  (https://github.com/fmtlib/fmt/issues/1685).
-
-- Applied extern templates to improve compile times when using the
-  core API and `fmt/format.h`
-  (https://github.com/fmtlib/fmt/issues/1452). For example,
-  on macOS with clang the compile time of a test translation unit
-  dropped from 2.3s to 0.3s with `-O2` and from 0.6s to 0.3s with the
-  default settings (`-O0`).
-
-  Before (`-O2`):
-
-      % time c++ -c test.cc -I include -std=c++17 -O2
-      c++ -c test.cc -I include -std=c++17 -O2  2.22s user 0.08s system 99% cpu 2.311 total
-
-  After (`-O2`):
-
-      % time c++ -c test.cc -I include -std=c++17 -O2
-      c++ -c test.cc -I include -std=c++17 -O2  0.26s user 0.04s system 98% cpu 0.303 total
-
-  Before (default):
-
-      % time c++ -c test.cc -I include -std=c++17
-      c++ -c test.cc -I include -std=c++17  0.53s user 0.06s system 98% cpu 0.601 total
-
-  After (default):
-
-      % time c++ -c test.cc -I include -std=c++17
-      c++ -c test.cc -I include -std=c++17  0.24s user 0.06s system 98% cpu 0.301 total
-
-  It is still recommended to use `fmt/core.h` instead of
-  `fmt/format.h` but the compile time difference is now smaller.
-  Thanks @alex3d for the suggestion.
-
-- Named arguments are now stored on stack (no dynamic memory
-  allocations) and the compiled code is more compact and efficient.
-  For example
-
-  ```c++
-  #include <fmt/core.h>
-
-  int main() {
-    fmt::print("The answer is {answer}\n", fmt::arg("answer", 42));
-  }
-  ```
-
-  compiles to just ([godbolt](https://godbolt.org/z/NcfEp_))
-
-  ```asm
-  .LC0:
-          .string "answer"
-  .LC1:
-          .string "The answer is {answer}\n"
-  main:
-          sub     rsp, 56
-          mov     edi, OFFSET FLAT:.LC1
-          mov     esi, 23
-          movabs  rdx, 4611686018427387905
-          lea     rax, [rsp+32]
-          lea     rcx, [rsp+16]

-
-  Thanks @BRevzin.
-
-- Added support for named arguments, `clear` and `reserve` to
-  `dynamic_format_arg_store`
-  (https://github.com/fmtlib/fmt/issues/1655,
-  https://github.com/fmtlib/fmt/pull/1663,
-  https://github.com/fmtlib/fmt/pull/1674,
-  https://github.com/fmtlib/fmt/pull/1677). Thanks @vsolontsov-ll.
-
-- Added support for the `'c'` format specifier to integral types for
-  compatibility with `std::format`
-  (https://github.com/fmtlib/fmt/issues/1652).
-
-- Replaced the `'n'` format specifier with `'L'` for compatibility
-  with `std::format`
-  (https://github.com/fmtlib/fmt/issues/1624). The `'n'`
-  specifier can be enabled via the `FMT_DEPRECATED_N_SPECIFIER` macro.
-
-- The `'='` format specifier is now disabled by default for
-  compatibility with `std::format`. It can be enabled via the
-  `FMT_DEPRECATED_NUMERIC_ALIGN` macro.
-
-- Removed the following deprecated APIs:
-
-  -   `FMT_STRING_ALIAS` and `fmt` macros - replaced by `FMT_STRING`
-  -   `fmt::basic_string_view::char_type` - replaced by
-      `fmt::basic_string_view::value_type`
-  -   `convert_to_int`
-  -   `format_arg_store::types`
-  -   `*parse_context` - replaced by `*format_parse_context`
-  -   `FMT_DEPRECATED_INCLUDE_OS`
-  -   `FMT_DEPRECATED_PERCENT` - incompatible with `std::format`
-  -   `*writer` - replaced by compiled format API
-
-- Renamed the `internal` namespace to `detail`
-  (https://github.com/fmtlib/fmt/issues/1538). The former is
-  still provided as an alias if the `FMT_USE_INTERNAL` macro is
-  defined.
-
-- Improved compatibility between `fmt::printf` with the standard specs
-  (https://github.com/fmtlib/fmt/issues/1595,
-  https://github.com/fmtlib/fmt/pull/1682,
-  https://github.com/fmtlib/fmt/pull/1683,

-
-- Fixed handling of `operator<<` overloads that use `copyfmt`
-  (https://github.com/fmtlib/fmt/issues/1666).
-
-- Added the `FMT_OS` CMake option to control inclusion of OS-specific
-  APIs in the fmt target. This can be useful for embedded platforms
-  (https://github.com/fmtlib/fmt/issues/1654,
-  https://github.com/fmtlib/fmt/pull/1656). Thanks @kwesolowski.
-
-- Replaced `FUZZING_BUILD_MODE_UNSAFE_FOR_PRODUCTION` with the
-  `FMT_FUZZ` macro to prevent interfering with fuzzing of projects
-  using {fmt} (https://github.com/fmtlib/fmt/pull/1650).
-  Thanks @asraa.
-
-- Fixed compatibility with emscripten
-  (https://github.com/fmtlib/fmt/issues/1636,

-# 6.2.1 - 2020-05-09
-
-- Fixed ostream support in `sprintf`
-  (https://github.com/fmtlib/fmt/issues/1631).
-- Fixed type detection when using implicit conversion to `string_view`
-  and ostream `operator<<` inconsistently
-  (https://github.com/fmtlib/fmt/issues/1662).
-
-# 6.2.0 - 2020-04-05
-
-- Improved error reporting when trying to format an object of a
-  non-formattable type:
-
-  ```c++
-  fmt::format("{}", S());
-  ```
-
-  now gives:
-
-      include/fmt/core.h:1015:5: error: static_assert failed due to requirement
-      'formattable' "Cannot format argument. To make type T formattable provide a
-      formatter<T> specialization:

-
-  if `S` is not formattable.
-
-- Reduced the library size by \~10%.
-
-- Always print decimal point if `#` is specified
-  (https://github.com/fmtlib/fmt/issues/1476,
-  https://github.com/fmtlib/fmt/issues/1498):
-
-  ```c++
-  fmt::print("{:#.0f}", 42.0);
-  ```
-
-  now prints `42.`
-
-- Implemented the `'L'` specifier for locale-specific numeric
-  formatting to improve compatibility with `std::format`. The `'n'`
-  specifier is now deprecated and will be removed in the next major
-  release.
-
-- Moved OS-specific APIs such as `windows_error` from `fmt/format.h`
-  to `fmt/os.h`. You can define `FMT_DEPRECATED_INCLUDE_OS` to
-  automatically include `fmt/os.h` from `fmt/format.h` for
-  compatibility but this will be disabled in the next major release.
-
-- Added precision overflow detection in floating-point formatting.
-
-- Implemented detection of invalid use of `fmt::arg`.
-
-- Used `type_identity` to block unnecessary template argument
-  deduction. Thanks Tim Song.
-
-- Improved UTF-8 handling
-  (https://github.com/fmtlib/fmt/issues/1109):

-
-  now prints:
-
-      ┌────────────────────┐
-      │    Привет, мир!    │
-      └────────────────────┘
-
-  on systems that support Unicode.
-
-- Added experimental dynamic argument storage
-  (https://github.com/fmtlib/fmt/issues/1170,
-  https://github.com/fmtlib/fmt/pull/1584):
-
-  ```c++
-  fmt::dynamic_format_arg_store<fmt::format_context> store;
-  store.push_back("answer");

-  (https://github.com/fmtlib/fmt/pull/1553). Thanks @dominicpoeschko.
-
-- Added the ability to disable floating-point formatting via
-  `FMT_USE_FLOAT`, `FMT_USE_DOUBLE` and `FMT_USE_LONG_DOUBLE` macros
-  for extremely memory-constrained embedded system
-  (https://github.com/fmtlib/fmt/pull/1590). Thanks @albaguirre.
-
-- Made `FMT_STRING` work with `constexpr` `string_view`
-  (https://github.com/fmtlib/fmt/pull/1589). Thanks @scramsby.
-
-- Implemented a minor optimization in the format string parser
-  (https://github.com/fmtlib/fmt/pull/1560). Thanks @IkarusDeveloper.

-
-- Fixed ABI compatibility with `libfmt.so.6.0.0`
-  (https://github.com/fmtlib/fmt/issues/1471).
-- Fixed handling types convertible to `std::string_view`
-  (https://github.com/fmtlib/fmt/pull/1451). Thanks @denizevrenci.
-- Made CUDA test an opt-in enabled via the `FMT_CUDA_TEST` CMake
-  option.
-- Fixed sign conversion warnings
-  (https://github.com/fmtlib/fmt/pull/1440). Thanks @0x8000-0000.
-
-# 6.1.1 - 2019-12-04
-
-- Fixed shared library build on Windows

-  https://github.com/fmtlib/fmt/issues/1445,
-  https://github.com/fmtlib/fmt/pull/1446,
-  https://github.com/fmtlib/fmt/issues/1450).
-  Thanks @egorpugin and @bbolli.
-- Added a missing decimal point in exponent notation with trailing
-  zeros.
-- Removed deprecated `format_arg_store::TYPES`.
-
-# 6.1.0 - 2019-12-01
-
-- {fmt} now formats IEEE 754 `float` and `double` using the shortest
-  decimal representation with correct rounding by default:
-
-  ```c++
-  #include <cmath>
-  #include <fmt/core.h>
-
-  int main() {
-    fmt::print("{}", M_PI);
-  }
-  ```
-
-  prints `3.141592653589793`.
-
-- Made the fast binary to decimal floating-point formatter the
-  default, simplified it and improved performance. {fmt} is now 15
-  times faster than libc++\'s `std::ostringstream`, 11 times faster
-  than `printf` and 10% faster than double-conversion on
-  [dtoa-benchmark](https://github.com/fmtlib/dtoa-benchmark):
-
-  | Function      | Time (ns) | Speedup |
-  | ------------- | --------: | ------: |
-  | ostringstream | 1,346.30  | 1.00x   |
-  | ostrstream    | 1,195.74  | 1.13x   |

-
-- {fmt} no longer converts `float` arguments to `double`. In
-  particular this improves the default (shortest) representation of
-  floats and makes `fmt::format` consistent with `std::format` specs
-  (https://github.com/fmtlib/fmt/issues/1336,
-  https://github.com/fmtlib/fmt/issues/1353,
-  https://github.com/fmtlib/fmt/pull/1360,
-  https://github.com/fmtlib/fmt/pull/1361):
-
-  ```c++
-  fmt::print("{}", 0.1f);
-  ```
-
-  prints `0.1` instead of `0.10000000149011612`.
-
-  Thanks @orivej.
-
-- Made floating-point formatting output consistent with
-  `printf`/iostreams
-  (https://github.com/fmtlib/fmt/issues/1376,
-  https://github.com/fmtlib/fmt/issues/1417).
-
-- Added support for 128-bit integers
-  (https://github.com/fmtlib/fmt/pull/1287):
-
-  ```c++
-  fmt::print("{}", std::numeric_limits<__int128_t>::max());
-  ```
-
-  prints `170141183460469231731687303715884105727`.
-
-  Thanks @denizevrenci.
-
-- The overload of `print` that takes `text_style` is now atomic, i.e.
-  the output from different threads doesn\'t interleave
-  (https://github.com/fmtlib/fmt/pull/1351). Thanks @tankiJong.
-
-- Made compile time in the header-only mode \~20% faster by reducing
-  the number of template instantiations. `wchar_t` overload of
-  `vprint` was moved from `fmt/core.h` to `fmt/format.h`.
-
-- Added an overload of `fmt::join` that works with tuples
-  (https://github.com/fmtlib/fmt/issues/1322,
-  https://github.com/fmtlib/fmt/pull/1330):
-
-  ```c++
-  #include <tuple>
-  #include <fmt/ranges.h>
-
-  int main() {
-    std::tuple<char, int, float> t{'a', 1, 2.0f};
-    fmt::print("{}", t);
-  }
-  ```
-
-  prints `('a', 1, 2.0)`.
-
-  Thanks @jeremyong.
-
-- Changed formatting of octal zero with prefix from \"00\" to \"0\":
-
-  ```c++
-  fmt::print("{:#o}", 0);
-  ```
-
-  prints `0`.
-
-- The locale is now passed to ostream insertion (`<<`) operators
-  (https://github.com/fmtlib/fmt/pull/1406):
-
-  ```c++
-  #include <fmt/locale.h>
-  #include <fmt/ostream.h>
-
-  struct S {
-    double value;
-  };
-
-  std::ostream& operator<<(std::ostream& os, S s) {
-    return os << s.value;
-  }
-
-  int main() {
-    auto s = fmt::format(std::locale("fr_FR.UTF-8"), "{}", S{0.42});
-    // s == "0,42"
-  }
-  ```
-
-  Thanks @dlaugt.
-

-  https://github.com/fmtlib/fmt/pull/1394). Thanks @skrdaniel.
-
-- Fixed handling of types with deleted implicit rvalue conversion to
-  `const char**` (https://github.com/fmtlib/fmt/issues/1421):
-
-  ```c++
-  struct mystring {
-    operator const char*() const&;
-    operator const char*() &;
-    operator const char*() const&& = delete;
-    operator const char*() && = delete;
-  };
-  mystring str;
-  fmt::print("{}", str); // now compiles
-  ```
-

-
-# 6.0.0 - 2019-08-26
-
-- Switched to the [MIT license](
-  https://github.com/fmtlib/fmt/blob/5a4b24613ba16cc689977c3b5bd8274a3ba1dd1f/LICENSE.rst)
-  with an optional exception that allows distributing binary code
-  without attribution.
-
-- Floating-point formatting is now locale-independent by default:
-
-  ```c++
-  #include <locale>
-  #include <fmt/core.h>
-
-  int main() {
-    std::locale::global(std::locale("ru_RU.UTF-8"));
-    fmt::print("value = {}", 4.2);
-  }
-  ```
-
-  prints \"value = 4.2\" regardless of the locale.
-
-  For locale-specific formatting use the `n` specifier:
-
-  ```c++
-  std::locale::global(std::locale("ru_RU.UTF-8"));
-  fmt::print("value = {:n}", 4.2);
-  ```
-
-  prints \"value = 4,2\".
-
-- Added an experimental Grisu floating-point formatting algorithm
-  implementation (disabled by default). To enable it compile with the
-  `FMT_USE_GRISU` macro defined to 1:
-
-  ```c++
-  #define FMT_USE_GRISU 1
-  #include <fmt/format.h>
-
-  auto s = fmt::format("{}", 4.2); // formats 4.2 using Grisu
-  ```
-
-  With Grisu enabled, {fmt} is 13x faster than `std::ostringstream`
-  (libc++) and 10x faster than `sprintf` on
-  [dtoa-benchmark](https://github.com/fmtlib/dtoa-benchmark) ([full
-  results](https://fmt.dev/unknown_mac64_clang10.0.html)):
-
-  ![](https://user-images.githubusercontent.com/576385/54883977-9fe8c000-4e28-11e9-8bde-272d122e7c52.jpg)
-
-- Separated formatting and parsing contexts for consistency with
-  [C++20 std::format](http://eel.is/c++draft/format), removing the
-  undocumented `basic_format_context::parse_context()` function.
-
-- Added [oss-fuzz](https://github.com/google/oss-fuzz) support
-  (https://github.com/fmtlib/fmt/pull/1199). Thanks @pauldreik.
-
-- `formatter` specializations now always take precedence over
-  `operator<<` (https://github.com/fmtlib/fmt/issues/952):
-
-  ```c++
-  #include <iostream>
-  #include <fmt/ostream.h>
-
-  struct S {};
-
-  std::ostream& operator<<(std::ostream& os, S) {
-    return os << 1;
-  }
-
-  template <>
-  struct fmt::formatter<S> : fmt::formatter<int> {
-    auto format(S, format_context& ctx) {
-      return formatter<int>::format(2, ctx);
-    }
-  };
-
-  int main() {
-    std::cout << S() << "\n"; // prints 1 using operator<<
-    fmt::print("{}\n", S());  // prints 2 using formatter
-  }
-  ```
-
-- Introduced the experimental `fmt::compile` function that does format
-  string compilation
-  (https://github.com/fmtlib/fmt/issues/618,
-  https://github.com/fmtlib/fmt/issues/1169,
-  https://github.com/fmtlib/fmt/pull/1171):
-
-  ```c++
-  #include <fmt/compile.h>
-
-  auto f = fmt::compile<int>("{}");
-  std::string s = fmt::format(f, 42); // can be called multiple times to
-                                      // format different values
-  // s == "42"
-  ```
-
-  It moves the cost of parsing a format string outside of the format
-  function which can be beneficial when identically formatting many
-  objects of the same types. Thanks @stryku.
-
-- Added experimental `%` format specifier that formats floating-point
-  values as percentages
-  (https://github.com/fmtlib/fmt/pull/1060,
-  https://github.com/fmtlib/fmt/pull/1069,
-  https://github.com/fmtlib/fmt/pull/1071):
-
-  ```c++
-  auto s = fmt::format("{:.1%}", 0.42); // s == "42.0%"
-  ```
-
-  Thanks @gawain-bolton.
-
-- Implemented precision for floating-point durations
-  (https://github.com/fmtlib/fmt/issues/1004,
-  https://github.com/fmtlib/fmt/pull/1012):
-
-  ```c++
-  auto s = fmt::format("{:.1}", std::chrono::duration<double>(1.234));
-  // s == 1.2s
-  ```
-
-  Thanks @DanielaE.
-
-- Implemented `chrono` format specifiers `%Q` and `%q` that give the
-  value and the unit respectively
-  (https://github.com/fmtlib/fmt/pull/1019):
-
-  ```c++
-  auto value = fmt::format("{:%Q}", 42s); // value == "42"
-  auto unit  = fmt::format("{:%q}", 42s); // unit == "s"
-  ```
-
-  Thanks @DanielaE.
-
-- Fixed handling of dynamic width in chrono formatter:
-
-  ```c++
-  auto s = fmt::format("{0:{1}%H:%M:%S}", std::chrono::seconds(12345), 12);
-  //                        ^ width argument index                     ^ width
-  // s == "03:25:45    "
-  ```
-
-  Thanks Howard Hinnant.
-
-- Removed deprecated `fmt/time.h`. Use `fmt/chrono.h` instead.
-
-- Added `fmt::format` and `fmt::vformat` overloads that take
-  `text_style` (https://github.com/fmtlib/fmt/issues/993,
-  https://github.com/fmtlib/fmt/pull/994):
-
-  ```c++
-  #include <fmt/color.h>
-
-  std::string message = fmt::format(fmt::emphasis::bold | fg(fmt::color::red),
-                                    "The answer is {}.", 42);
-  ```
-
-  Thanks @Naios.
-
-- Removed the deprecated color API (`print_colored`). Use the new API,
-  namely `print` overloads that take `text_style` instead.
-
-- Made `std::unique_ptr` and `std::shared_ptr` formattable as pointers
-  via `fmt::ptr` (https://github.com/fmtlib/fmt/pull/1121):
-
-  ```c++
-  std::unique_ptr<int> p = ...;
-  fmt::print("{}", fmt::ptr(p)); // prints p as a pointer
-  ```
-
-  Thanks @sighingnow.
-
-- Made `print` and `vprint` report I/O errors
-  (https://github.com/fmtlib/fmt/issues/1098,
-  https://github.com/fmtlib/fmt/pull/1099). Thanks @BillyDonahue.
-
-- Marked deprecated APIs with the `[[deprecated]]` attribute and
-  removed internal uses of deprecated APIs
-  (https://github.com/fmtlib/fmt/pull/1022). Thanks @eliaskosunen.
-
-- Modernized the codebase using more C++11 features and removing
-  workarounds. Most importantly, `buffer_context` is now an alias
-  template, so use `buffer_context<T>` instead of
-  `buffer_context<T>::type`. These features require GCC 4.8 or later.
-
-- `formatter` specializations now always take precedence over implicit
-  conversions to `int` and the undocumented `convert_to_int` trait is
-  now deprecated.
-
-- Moved the undocumented `basic_writer`, `writer`, and `wwriter` types
-  to the `internal` namespace.
-
-- Removed deprecated `basic_format_context::begin()`. Use `out()`
-  instead.
-
-- Disallowed passing the result of `join` as an lvalue to prevent
-  misuse.
-
-- Refactored the undocumented structs that represent parsed format
-  specifiers to simplify the API and allow multibyte fill.
-
-- Moved SFINAE to template parameters to reduce symbol sizes.
-
-- Switched to `fputws` for writing wide strings so that it\'s no
-  longer required to call `_setmode` on Windows
-  (https://github.com/fmtlib/fmt/issues/1229,
-  https://github.com/fmtlib/fmt/pull/1243). Thanks @jackoalan.
-
-- Improved literal-based API
-  (https://github.com/fmtlib/fmt/pull/1254). Thanks @sylveon.
-
-- Added support for exotic platforms without `uintptr_t` such as IBM i
-  (AS/400) which has 128-bit pointers and only 64-bit integers
-  (https://github.com/fmtlib/fmt/issues/1059).
-
-- Added [Sublime Text syntax highlighting config](
-  https://github.com/fmtlib/fmt/blob/master/support/C%2B%2B.sublime-syntax)
-  (https://github.com/fmtlib/fmt/issues/1037). Thanks @Kronuz.
-
-- Added the `FMT_ENFORCE_COMPILE_STRING` macro to enforce the use of
-  compile-time format strings
-  (https://github.com/fmtlib/fmt/pull/1231). Thanks @jackoalan.
-
-- Stopped setting `CMAKE_BUILD_TYPE` if {fmt} is a subproject
-  (https://github.com/fmtlib/fmt/issues/1081).
-
-- Various build improvements
-  (https://github.com/fmtlib/fmt/pull/1039,

-# 5.3.0 - 2018-12-28
-
-- Introduced experimental chrono formatting support:
-
-  ```c++
-  #include <fmt/chrono.h>
-
-  int main() {
-    using namespace std::literals::chrono_literals;
-    fmt::print("Default format: {} {}\n", 42s, 100ms);
-    fmt::print("strftime-like format: {:%H:%M:%S}\n", 3h + 15min + 30s);
-  }
-  ```
-
-  prints:
-
-      Default format: 42s 100ms
-      strftime-like format: 03:15:30
-
-- Added experimental support for emphasis (bold, italic, underline,
-  strikethrough), colored output to a file stream, and improved
-  colored formatting API
-  (https://github.com/fmtlib/fmt/pull/961,
-  https://github.com/fmtlib/fmt/pull/967,
-  https://github.com/fmtlib/fmt/pull/973):
-
-  ```c++
-  #include <fmt/color.h>
-
-  int main() {
-    print(fg(fmt::color::crimson) | fmt::emphasis::bold,
-          "Hello, {}!\n", "world");
-    print(fg(fmt::color::floral_white) | bg(fmt::color::slate_gray) |
-          fmt::emphasis::underline, "Hello, {}!\n", "мир");
-    print(fg(fmt::color::steel_blue) | fmt::emphasis::italic,
-          "Hello, {}!\n", "世界");
-  }
-  ```
-
-  prints the following on modern terminals with RGB color support:

-- Added support for 4-bit terminal colors
-  (https://github.com/fmtlib/fmt/issues/968,
-  https://github.com/fmtlib/fmt/pull/974)
-
-  ```c++
-  #include <fmt/color.h>
-
-  int main() {
-    print(fg(fmt::terminal_color::red), "stop\n");
-  }
-  ```
-
-  Note that these colors vary by terminal:

-- Parameterized formatting functions on the type of the format string
-  (https://github.com/fmtlib/fmt/issues/880,
-  https://github.com/fmtlib/fmt/pull/881,
-  https://github.com/fmtlib/fmt/pull/883,
-  https://github.com/fmtlib/fmt/pull/885,
-  https://github.com/fmtlib/fmt/pull/897,
-  https://github.com/fmtlib/fmt/issues/920). Any object of
-  type `S` that has an overloaded `to_string_view(const S&)` returning
-  `fmt::string_view` can be used as a format string:
-
-  ```c++
-  namespace my_ns {
-  inline string_view to_string_view(const my_string& s) {
-    return {s.data(), s.length()};
-  }
-  }
-
-  std::string message = fmt::format(my_string("The answer is {}."), 42);
-  ```
-
-  Thanks @DanielaE.
-
-- Made `std::string_view` work as a format string
-  (https://github.com/fmtlib/fmt/pull/898):
-
-  ```c++
-  auto message = fmt::format(std::string_view("The answer is {}."), 42);
-  ```
-
-  Thanks @DanielaE.
-
-- Added wide string support to compile-time format string checks
-  (https://github.com/fmtlib/fmt/pull/924):
-
-  ```c++
-  print(fmt(L"{:f}"), 42); // compile-time error: invalid type specifier
-  ```
-
-  Thanks @XZiar.
-
-- Made colored print functions work with wide strings
-  (https://github.com/fmtlib/fmt/pull/867):
-
-  ```c++
-  #include <fmt/color.h>
-
-  int main() {
-    print(fg(fmt::color::red), L"{}\n", 42);
-  }
-  ```
-
-  Thanks @DanielaE.
-
-- Introduced experimental Unicode support
-  (https://github.com/fmtlib/fmt/issues/628,
-  https://github.com/fmtlib/fmt/pull/891):
-
-  ```c++
-  using namespace fmt::literals;
-  auto s = fmt::format("{:*^5}"_u, "🤡"_u); // s == "**🤡**"_u
-  ```
-
-- Improved locale support:
-
-  ```c++
-  #include <fmt/locale.h>
-
-  struct numpunct : std::numpunct<char> {
-   protected:
-    char do_thousands_sep() const override { return '~'; }
-  };
-
-  std::locale loc;
-  auto s = fmt::format(std::locale(loc, new numpunct()), "{:n}", 1234567);
-  // s == "1~234~567"
-  ```
-
-- Constrained formatting functions on proper iterator types
-  (https://github.com/fmtlib/fmt/pull/921). Thanks @DanielaE.
-
-- Added `make_printf_args` and `make_wprintf_args` functions
-  (https://github.com/fmtlib/fmt/pull/934). Thanks @tnovotny.
-
-- Deprecated `fmt::visit`, `parse_context`, and `wparse_context`. Use
-  `fmt::visit_format_arg`, `format_parse_context`, and
-  `wformat_parse_context` instead.
-
-- Removed undocumented `basic_fixed_buffer` which has been superseded
-  by the iterator-based API
-  (https://github.com/fmtlib/fmt/issues/873,
-  https://github.com/fmtlib/fmt/pull/902). Thanks @superfunc.
-
-- Disallowed repeated leading zeros in an argument ID:
-
-  ```c++
-  fmt::print("{000}", 42); // error
-  ```
-
-- Reintroduced support for gcc 4.4.
-
-- Fixed compilation on platforms with exotic `double`
-  (https://github.com/fmtlib/fmt/issues/878).
-
-- Improved documentation
-  (https://github.com/fmtlib/fmt/issues/164,

-# 5.2.1 - 2018-09-21
-
-- Fixed `visit` lookup issues on gcc 7 & 8
-  (https://github.com/fmtlib/fmt/pull/870). Thanks @medithe.
-- Fixed linkage errors on older gcc.
-- Prevented `fmt/range.h` from specializing `fmt::basic_string_view`
-  (https://github.com/fmtlib/fmt/issues/865,
-  https://github.com/fmtlib/fmt/pull/868). Thanks @hhggit.
-- Improved error message when formatting unknown types
-  (https://github.com/fmtlib/fmt/pull/872). Thanks @foonathan.
-- Disabled templated user-defined literals when compiled under nvcc
-  (https://github.com/fmtlib/fmt/pull/875). Thanks @CandyGumdrop.
-- Fixed `format_to` formatting to `wmemory_buffer`
-  (https://github.com/fmtlib/fmt/issues/874).
-
-# 5.2.0 - 2018-09-13
-
-- Optimized format string parsing and argument processing which
-  resulted in up to 5x speed up on long format strings and significant
-  performance boost on various benchmarks. For example, version 5.2 is
-  2.22x faster than 5.1 on decimal integer formatting with `format_to`
-  (macOS, clang-902.0.39.2):
-
-  | Method                     | Time, s         | Speedup |
-  | -------------------------- | --------------: | ------: |
-  | fmt::format 5.1            | 0.58            |         |
-  | fmt::format 5.2            | 0.35            |   1.66x |
-  | fmt::format_to 5.1         | 0.51            |         |
-  | fmt::format_to 5.2         | 0.23            |   2.22x |
-  | sprintf                    | 0.71            |         |
-  | std::to_string             | 1.01            |         |
-  | std::stringstream          | 1.73            |         |
-
-- Changed the `fmt` macro from opt-out to opt-in to prevent name
-  collisions. To enable it define the `FMT_STRING_ALIAS` macro to 1
-  before including `fmt/format.h`:
-
-  ```c++
-  #define FMT_STRING_ALIAS 1
-  #include <fmt/format.h>
-  std::string answer = format(fmt("{}"), 42);
-  ```
-
-- Added compile-time format string checks to `format_to` overload that
-  takes `fmt::memory_buffer`
-  (https://github.com/fmtlib/fmt/issues/783):
-
-  ```c++
-  fmt::memory_buffer buf;
-  // Compile-time error: invalid type specifier.
-  fmt::format_to(buf, fmt("{:d}"), "foo");
-  ```
-
-- Moved experimental color support to `fmt/color.h` and enabled the
-  new API by default. The old API can be enabled by defining the
-  `FMT_DEPRECATED_COLORS` macro.
-
-- Added formatting support for types explicitly convertible to
-  `fmt::string_view`:
-
-  ```c++
-  struct foo {
-    explicit operator fmt::string_view() const { return "foo"; }
-  };
-  auto s = format("{}", foo());
-  ```
-
-  In particular, this makes formatting function work with
-  `folly::StringPiece`.
-
-- Implemented preliminary support for `char*_t` by replacing the
-  `format` function overloads with a single function template
-  parameterized on the string type.
-
-- Added support for dynamic argument lists
-  (https://github.com/fmtlib/fmt/issues/814,
-  https://github.com/fmtlib/fmt/pull/819). Thanks @MikePopoloski.
-
-- Reduced executable size overhead for embedded targets using newlib
-  nano by making locale dependency optional
-  (https://github.com/fmtlib/fmt/pull/839). Thanks @teajay-fr.
-
-- Keep `noexcept` specifier when exceptions are disabled
-  (https://github.com/fmtlib/fmt/issues/801,
-  https://github.com/fmtlib/fmt/pull/810). Thanks @qis.
-
-- Fixed formatting of user-defined types providing `operator<<` with
-  `format_to_n` (https://github.com/fmtlib/fmt/pull/806).
-  Thanks @mkurdej.
-
-- Fixed dynamic linkage of new symbols
-  (https://github.com/fmtlib/fmt/issues/808).
-
-- Fixed global initialization issue
-  (https://github.com/fmtlib/fmt/issues/807):
-
-  ```c++
-  // This works on compilers with constexpr support.
-  static const std::string answer = fmt::format("{}", 42);
-  ```
-
-- Fixed various compiler warnings and errors
-  (https://github.com/fmtlib/fmt/pull/804,
-  https://github.com/fmtlib/fmt/issues/809,
-  https://github.com/fmtlib/fmt/pull/811,

-  Thanks @henryiii, @medithe, and @eliasdaler.
-
-# 5.1.0 - 2018-07-05
-
-- Added experimental support for RGB color output enabled with the
-  `FMT_EXTENDED_COLORS` macro:
-
-  ```c++
-  #define FMT_EXTENDED_COLORS
-  #define FMT_HEADER_ONLY // or compile fmt with FMT_EXTENDED_COLORS defined
-  #include <fmt/format.h>
-
-  fmt::print(fmt::color::steel_blue, "Some beautiful text");
-  ```
-
-  The old API (the `print_colored` and `vprint_colored` functions and
-  the `color` enum) is now deprecated.
-  (https://github.com/fmtlib/fmt/issues/762
-  https://github.com/fmtlib/fmt/pull/767). thanks @Remotion.
-
-- Added quotes to strings in ranges and tuples
-  (https://github.com/fmtlib/fmt/pull/766). Thanks @Remotion.
-
-- Made `format_to` work with `basic_memory_buffer`
-  (https://github.com/fmtlib/fmt/issues/776).
-
-- Added `vformat_to_n` and `wchar_t` overload of `format_to_n`
-  (https://github.com/fmtlib/fmt/issues/764,
-  https://github.com/fmtlib/fmt/issues/769).
-
-- Made `is_range` and `is_tuple_like` part of public (experimental)
-  API to allow specialization for user-defined types
-  (https://github.com/fmtlib/fmt/issues/751,
-  https://github.com/fmtlib/fmt/pull/759). Thanks @drrlvn.
-
-- Added more compilers to continuous integration and increased
-  `FMT_PEDANTIC` warning levels
-  (https://github.com/fmtlib/fmt/pull/736). Thanks @eliaskosunen.
-
-- Fixed compilation with MSVC 2013.
-
-- Fixed handling of user-defined types in `format_to`
-  (https://github.com/fmtlib/fmt/issues/793).
-
-- Forced linking of inline `vformat` functions into the library
-  (https://github.com/fmtlib/fmt/issues/795).
-
-- Fixed incorrect call to on_align in `'{:}='`
-  (https://github.com/fmtlib/fmt/issues/750).
-
-- Fixed floating-point formatting to a non-back_insert_iterator with
-  sign & numeric alignment specified

-# 5.0.0 - 2018-05-21
-
-- Added a requirement for partial C++11 support, most importantly
-  variadic templates and type traits, and dropped `FMT_VARIADIC_*`
-  emulation macros. Variadic templates are available since GCC 4.4,
-  Clang 2.9 and MSVC 18.0 (2013). For older compilers use {fmt}
-  [version 4.x](https://github.com/fmtlib/fmt/releases/tag/4.1.0)
-  which continues to be maintained and works with C++98 compilers.
-
-- Renamed symbols to follow standard C++ naming conventions and
-  proposed a subset of the library for standardization in [P0645R2
-  Text Formatting](https://wg21.link/P0645).
-
-- Implemented `constexpr` parsing of format strings and [compile-time
-  format string
-  checks](https://fmt.dev/latest/api.html#compile-time-format-string-checks).
-  For example
-
-  ```c++
-  #include <fmt/format.h>
-
-  std::string s = format(fmt("{:d}"), "foo");
-  ```
-
-  gives a compile-time error because `d` is an invalid specifier for
-  strings ([godbolt](https://godbolt.org/g/rnCy9Q)):
-
-      ...
-      <source>:4:19: note: in instantiation of function template specialization 'fmt::v5::format<S, char [4]>' requested here
-        std::string s = format(fmt("{:d}"), "foo");
-                        ^
-      format.h:1337:13: note: non-constexpr function 'on_error' cannot be used in a constant expression
-          handler.on_error("invalid type specifier");
-
-  Compile-time checks require relaxed `constexpr` (C++14 feature)
-  support. If the latter is not available, checks will be performed at
-  runtime.
-
-- Separated format string parsing and formatting in the extension API
-  to enable compile-time format string processing. For example
-
-  ```c++
-  struct Answer {};
-
-  namespace fmt {
-  template <>
-  struct formatter<Answer> {
-    constexpr auto parse(parse_context& ctx) {
-      auto it = ctx.begin();
-      spec = *it;
-      if (spec != 'd' && spec != 's')
-        throw format_error("invalid specifier");
-      return ++it;
-    }
-
-    template <typename FormatContext>
-    auto format(Answer, FormatContext& ctx) {
-      return spec == 's' ?
-        format_to(ctx.begin(), "{}", "fourty-two") :
-        format_to(ctx.begin(), "{}", 42);
-    }
-
-    char spec = 0;
-  };
-  }
-
-  std::string s = format(fmt("{:x}"), Answer());
-  ```
-
-  gives a compile-time error due to invalid format specifier
-  ([godbolt](https://godbolt.org/g/2jQ1Dv)):
-
-      ...
-      <source>:12:45: error: expression '<throw-expression>' is not a constant expression
-             throw format_error("invalid specifier");
-
-- Added [iterator
-  support](https://fmt.dev/latest/api.html#output-iterator-support):
-
-  ```c++
-  #include <vector>
-  #include <fmt/format.h>
-
-  std::vector<char> out;
-  fmt::format_to(std::back_inserter(out), "{}", 42);
-  ```
-
-- Added the
-  [format_to_n](https://fmt.dev/latest/api.html#_CPPv2N3fmt11format_to_nE8OutputItNSt6size_tE11string_viewDpRK4Args)
-  function that restricts the output to the specified number of
-  characters (https://github.com/fmtlib/fmt/issues/298):
-
-  ```c++
-  char out[4];
-  fmt::format_to_n(out, sizeof(out), "{}", 12345);
-  // out == "1234" (without terminating '\0')
-  ```
-
-- Added the [formatted_size](
-  https://fmt.dev/latest/api.html#_CPPv2N3fmt14formatted_sizeE11string_viewDpRK4Args)
-  function for computing the output size:
-
-  ```c++
-  #include <fmt/format.h>
-
-  auto size = fmt::formatted_size("{}", 12345); // size == 5
-  ```
-
-- Improved compile times by reducing dependencies on standard headers
-  and providing a lightweight [core
-  API](https://fmt.dev/latest/api.html#core-api):
-
-  ```c++
-  #include <fmt/core.h>
-
-  fmt::print("The answer is {}.", 42);
-  ```
-
-  See [Compile time and code
-  bloat](https://github.com/fmtlib/fmt#compile-time-and-code-bloat).
-
-- Added the [make_format_args](
-  https://fmt.dev/latest/api.html#_CPPv2N3fmt16make_format_argsEDpRK4Args)
-  function for capturing formatting arguments:
-
-  ```c++
-  // Prints formatted error message.
-  void vreport_error(const char *format, fmt::format_args args) {
-    fmt::print("Error: ");
-    fmt::vprint(format, args);
-  }
-  template <typename... Args>
-  void report_error(const char *format, const Args & ... args) {
-    vreport_error(format, fmt::make_format_args(args...));
-  }
-  ```
-
-- Added the `make_printf_args` function for capturing `printf`
-  arguments (https://github.com/fmtlib/fmt/issues/687,
-  https://github.com/fmtlib/fmt/pull/694). Thanks @Kronuz.
-
-- Added prefix `v` to non-variadic functions taking `format_args` to
-  distinguish them from variadic ones:
-
-  ```c++
-  std::string vformat(string_view format_str, format_args args);
-
-  template <typename... Args>
-  std::string format(string_view format_str, const Args & ... args);
-  ```
-
-- Added experimental support for formatting ranges, containers and
-  tuple-like types in `fmt/ranges.h`
-  (https://github.com/fmtlib/fmt/pull/735):
-
-  ```c++
-  #include <fmt/ranges.h>
-
-  std::vector<int> v = {1, 2, 3};
-  fmt::print("{}", v); // prints {1, 2, 3}
-  ```
-
-  Thanks @Remotion.
-
-- Implemented `wchar_t` date and time formatting
-  (https://github.com/fmtlib/fmt/pull/712):
-
-  ```c++
-  #include <fmt/time.h>
-
-  std::time_t t = std::time(nullptr);
-  auto s = fmt::format(L"The date is {:%Y-%m-%d}.", *std::localtime(&t));
-  ```
-
-  Thanks @DanielaE.
-
-- Provided more wide string overloads
-  (https://github.com/fmtlib/fmt/pull/724). Thanks @DanielaE.
-
-- Switched from a custom null-terminated string view class to
-  `string_view` in the format API and provided `fmt::string_view`
-  which implements a subset of `std::string_view` API for pre-C++17
-  systems.
-
-- Added support for `std::experimental::string_view`
-  (https://github.com/fmtlib/fmt/pull/607):
-
-  ```c++
-  #include <fmt/core.h>
-  #include <experimental/string_view>
-
-  fmt::print("{}", std::experimental::string_view("foo"));
-  ```
-
-  Thanks @virgiliofornazin.
-
-- Allowed mixing named and automatic arguments:
-
-  ```c++
-  fmt::format("{} {two}", 1, fmt::arg("two", 2));
-  ```
-
-- Removed the write API in favor of the [format
-  API](https://fmt.dev/latest/api.html#format-api) with compile-time
-  handling of format strings.
-
-- Disallowed formatting of multibyte strings into a wide character
-  target (https://github.com/fmtlib/fmt/pull/606).
-
-- Improved documentation
-  (https://github.com/fmtlib/fmt/pull/515,
-  https://github.com/fmtlib/fmt/issues/614,
-  https://github.com/fmtlib/fmt/pull/617,
-  https://github.com/fmtlib/fmt/pull/661,
-  https://github.com/fmtlib/fmt/pull/680).
-  Thanks @ibell, @mihaitodor and @johnthagen.
-
-- Implemented more efficient handling of large number of format
-  arguments.
-
-- Introduced an inline namespace for symbol versioning.
-
-- Added debug postfix `d` to the `fmt` library name
-  (https://github.com/fmtlib/fmt/issues/636).
-
-- Removed unnecessary `fmt/` prefix in includes
-  (https://github.com/fmtlib/fmt/pull/397). Thanks @chronoxor.
-
-- Moved `fmt/*.h` to `include/fmt/*.h` to prevent irrelevant files and
-  directories appearing on the include search paths when fmt is used

-
-# 3.0.0 - 2016-05-07
-
-- The project has been renamed from C++ Format (cppformat) to fmt for
-  consistency with the used namespace and macro prefix
-  (https://github.com/fmtlib/fmt/issues/307). Library headers
-  are now located in the `fmt` directory:
-
-  ```c++
-  #include "fmt/format.h"
-  ```
-
-  Including `format.h` from the `cppformat` directory is deprecated
-  but works via a proxy header which will be removed in the next major
-  version.
-
-  The documentation is now available at <https://fmt.dev>.
-
-- Added support for
-  [strftime](http://en.cppreference.com/w/cpp/chrono/c/strftime)-like
-  [date and time
-  formatting](https://fmt.dev/3.0.0/api.html#date-and-time-formatting)
-  (https://github.com/fmtlib/fmt/issues/283):
-
-  ```c++
-  #include "fmt/time.h"
-
-  std::time_t t = std::time(nullptr);
-  // Prints "The date is 2016-04-29." (with the current date)
-  fmt::print("The date is {:%Y-%m-%d}.", *std::localtime(&t));
-  ```
-
-- `std::ostream` support including formatting of user-defined types
-  that provide overloaded `operator<<` has been moved to
-  `fmt/ostream.h`:
-
-  ```c++
-  #include "fmt/ostream.h"
-
-  class Date {
-    int year_, month_, day_;
-  public:
-    Date(int year, int month, int day) : year_(year), month_(month), day_(day) {}
-
-    friend std::ostream &operator<<(std::ostream &os, const Date &d) {
-      return os << d.year_ << '-' << d.month_ << '-' << d.day_;
-    }
-  };
-
-  std::string s = fmt::format("The date is {}", Date(2012, 12, 9));
-  // s == "The date is 2012-12-9"
-  ```
-
-- Added support for [custom argument
-  formatters](https://fmt.dev/3.0.0/api.html#argument-formatters)
-  (https://github.com/fmtlib/fmt/issues/235).
-
-- Added support for locale-specific integer formatting with the `n`
-  specifier (https://github.com/fmtlib/fmt/issues/305):
-
-  ```c++
-  std::setlocale(LC_ALL, "en_US.utf8");
-  fmt::print("cppformat: {:n}\n", 1234567); // prints 1,234,567
-  ```
-
-- Sign is now preserved when formatting an integer with an incorrect
-  `printf` format specifier
-  (https://github.com/fmtlib/fmt/issues/265):
-
-  ```c++
-  fmt::printf("%lld", -42); // prints -42
-  ```
-
-  Note that it would be an undefined behavior in `std::printf`.
-
-- Length modifiers such as `ll` are now optional in printf formatting
-  functions and the correct type is determined automatically
-  (https://github.com/fmtlib/fmt/issues/255):
-
-  ```c++
-  fmt::printf("%d", std::numeric_limits<long long>::max());
-  ```
-
-  Note that it would be an undefined behavior in `std::printf`.
-
-- Added initial support for custom formatters
-  (https://github.com/fmtlib/fmt/issues/231).
-
-- Fixed detection of user-defined literal support on Intel C++
-  compiler (https://github.com/fmtlib/fmt/issues/311,
-  https://github.com/fmtlib/fmt/pull/312).
-  Thanks @dean0x7d and @speth.

-- \[Breaking\] Named arguments
-  (https://github.com/fmtlib/fmt/pull/169,
-  https://github.com/fmtlib/fmt/pull/173,
-  https://github.com/fmtlib/fmt/pull/174):
-
-  ```c++
-  fmt::print("The answer is {answer}.", fmt::arg("answer", 42));
-  ```
-
-  Thanks @jamboree.
-
-- \[Experimental\] User-defined literals for format and named
-  arguments (https://github.com/fmtlib/fmt/pull/204,
-  https://github.com/fmtlib/fmt/pull/206,
-  https://github.com/fmtlib/fmt/pull/207):
-
-  ```c++
-  using namespace fmt::literals;
-  fmt::print("The answer is {answer}.", "answer"_a=42);
-  ```
-
-  Thanks @dean0x7d.
-
-- \[Breaking\] Formatting of more than 16 arguments is now supported
-  when using variadic templates
-  (https://github.com/fmtlib/fmt/issues/141). Thanks @Shauren.
-
-- Runtime width specification
-  (https://github.com/fmtlib/fmt/pull/168):
-
-  ```c++
-  fmt::format("{0:{1}}", 42, 5); // gives "   42"
-  ```
-
-  Thanks @jamboree.
-
-- \[Breaking\] Enums are now formatted with an overloaded
-  `std::ostream` insertion operator (`operator<<`) if available
-  (https://github.com/fmtlib/fmt/issues/232).
-
-- \[Breaking\] Changed default `bool` format to textual, \"true\" or
-  \"false\" (https://github.com/fmtlib/fmt/issues/170):
-
-  ```c++
-  fmt::print("{}", true); // prints "true"
-  ```
-
-  To print `bool` as a number use numeric format specifier such as
-  `d`:
-
-  ```c++
-  fmt::print("{:d}", true); // prints "1"
-  ```
-
-- `fmt::printf` and `fmt::sprintf` now support formatting of `bool`
-  with the `%s` specifier giving textual output, \"true\" or \"false\"
-  (https://github.com/fmtlib/fmt/pull/223):
-
-  ```c++
-  fmt::printf("%s", true); // prints "true"
-  ```
-
-  Thanks @LarsGullik.
-
-- \[Breaking\] `signed char` and `unsigned char` are now formatted as
-  integers by default
-  (https://github.com/fmtlib/fmt/pull/217).
-
-- \[Breaking\] Pointers to C strings can now be formatted with the `p`
-  specifier (https://github.com/fmtlib/fmt/pull/223):
-
-  ```c++
-  fmt::print("{:p}", "test"); // prints pointer value
-  ```
-
-  Thanks @LarsGullik.
-
-- \[Breaking\] `fmt::printf` and `fmt::sprintf` now print null
-  pointers as `(nil)` and null strings as `(null)` for consistency
-  with glibc (https://github.com/fmtlib/fmt/pull/226).
-  Thanks @LarsGullik.
-
-- \[Breaking\] `fmt::(s)printf` now supports formatting of objects of
-  user-defined types that provide an overloaded `std::ostream`
-  insertion operator (`operator<<`)
-  (https://github.com/fmtlib/fmt/issues/201):
-
-  ```c++
-  fmt::printf("The date is %s", Date(2012, 12, 9));
-  ```
-
-- \[Breaking\] The `Buffer` template is now part of the public API and
-  can be used to implement custom memory buffers
-  (https://github.com/fmtlib/fmt/issues/140). Thanks @polyvertex.
-
-- \[Breaking\] Improved compatibility between `BasicStringRef` and
-  [std::experimental::basic_string_view](
-  http://en.cppreference.com/w/cpp/experimental/basic_string_view)
-  (https://github.com/fmtlib/fmt/issues/100,
-  https://github.com/fmtlib/fmt/issues/159,
-  https://github.com/fmtlib/fmt/issues/183):
-
-  -   Comparison operators now compare string content, not pointers
-  -   `BasicStringRef::c_str` replaced by `BasicStringRef::data`
-  -   `BasicStringRef` is no longer assumed to be null-terminated
-
-  References to null-terminated strings are now represented by a new
-  class, `BasicCStringRef`.
-
-- Dependency on pthreads introduced by Google Test is now optional
-  (https://github.com/fmtlib/fmt/issues/185).
-
-- New CMake options `FMT_DOC`, `FMT_INSTALL` and `FMT_TEST` to control
-  generation of `doc`, `install` and `test` targets respectively, on
-  by default (https://github.com/fmtlib/fmt/issues/197,
-  https://github.com/fmtlib/fmt/issues/198,
-  https://github.com/fmtlib/fmt/issues/200). Thanks @maddinat0r.
-
-- `noexcept` is now used when compiling with MSVC2015
-  (https://github.com/fmtlib/fmt/pull/215). Thanks @dmkrepo.
-
-- Added an option to disable use of `windows.h` when
-  `FMT_USE_WINDOWS_H` is defined as 0 before including `format.h`
-  (https://github.com/fmtlib/fmt/issues/171). Thanks @alfps.
-
-- \[Breaking\] `windows.h` is now included with `NOMINMAX` unless
-  `FMT_WIN_MINMAX` is defined. This is done to prevent breaking code
-  using `std::min` and `std::max` and only affects the header-only
-  configuration (https://github.com/fmtlib/fmt/issues/152,
-  https://github.com/fmtlib/fmt/pull/153,
-  https://github.com/fmtlib/fmt/pull/154). Thanks @DevO2012.
-
-- Improved support for custom character types
-  (https://github.com/fmtlib/fmt/issues/171). Thanks @alfps.
-
-- Added an option to disable use of IOStreams when `FMT_USE_IOSTREAMS`
-  is defined as 0 before including `format.h`
-  (https://github.com/fmtlib/fmt/issues/205,
-  https://github.com/fmtlib/fmt/pull/208). Thanks @JodiTheTigger.
-
-- Improved detection of `isnan`, `isinf` and `signbit`.
-
-## Optimization
-
-- Made formatting of user-defined types more efficient with a custom
-  stream buffer (https://github.com/fmtlib/fmt/issues/92,
-  https://github.com/fmtlib/fmt/pull/230). Thanks @NotImplemented.
-- Further improved performance of `fmt::Writer` on integer formatting
-  and fixed a minor regression. Now it is \~7% faster than
-  `karma::generate` on Karma\'s benchmark
-  (https://github.com/fmtlib/fmt/issues/186).
-- \[Breaking\] Reduced [compiled code
-  size](https://github.com/fmtlib/fmt#compile-time-and-code-bloat)
-  (https://github.com/fmtlib/fmt/issues/143,
-  https://github.com/fmtlib/fmt/pull/149).

-  ```
-
-- Added [0 A.D.](http://play0ad.com/) and [PenUltima Online

-  (https://github.com/fmtlib/fmt/pull/115,
-  https://github.com/fmtlib/fmt/pull/116,
-  https://github.com/fmtlib/fmt/pull/118 and

-
-- Added [changelog](https://github.com/fmtlib/fmt/blob/master/ChangeLog.md)
-  (https://github.com/fmtlib/fmt/issues/103).
-
-# 1.0.0 - 2015-02-05
-
-- Add support for a header-only configuration when `FMT_HEADER_ONLY`
-  is defined before including `format.h`:
-
-  ```c++
-  #define FMT_HEADER_ONLY
-  #include "format.h"
-  ```
-
-- Compute string length in the constructor of `BasicStringRef` instead
-  of the `size` method
-  (https://github.com/fmtlib/fmt/issues/79). This eliminates
-  size computation for string literals on reasonable optimizing
-  compilers.
-
-- Fix formatting of types with overloaded `operator <<` for
-  `std::wostream` (https://github.com/fmtlib/fmt/issues/86):
-
-  ```c++
-  fmt::format(L"The date is {0}", Date(2012, 12, 9));
-  ```
-
-- Fix linkage of tests on Arch Linux
-  (https://github.com/fmtlib/fmt/issues/89).
-
-- Allow precision specifier for non-float arguments
-  (https://github.com/fmtlib/fmt/issues/90):
-
-  ```c++
-  fmt::print("{:.3}\n", "Carpet"); // prints "Car"
-  ```
-
-- Fix build on Android NDK (https://github.com/fmtlib/fmt/issues/93).
-
-- Improvements to documentation build procedure.
-
-- Remove `FMT_SHARED` CMake variable in favor of standard [BUILD_SHARED_LIBS](
-  http://www.cmake.org/cmake/help/v3.0/variable/BUILD_SHARED_LIBS.html).
-
-- Fix error handling in `fmt::fprintf`.
-
-- Fix a number of warnings.
-
-# 0.12.0 - 2014-10-25
-
-- \[Breaking\] Improved separation between formatting and buffer
-  management. `Writer` is now a base class that cannot be instantiated
-  directly. The new `MemoryWriter` class implements the default buffer
-  management with small allocations done on stack. So `fmt::Writer`
-  should be replaced with `fmt::MemoryWriter` in variable
-  declarations.
-
-  Old code:
-
-  ```c++
-  fmt::Writer w;
-  ```
-
-  New code:
-
-  ```c++
-  fmt::MemoryWriter w;
-  ```
-
-  If you pass `fmt::Writer` by reference, you can continue to do so:
-
-  ```c++
-  void f(fmt::Writer &w);
-  ```
-
-  This doesn\'t affect the formatting API.
-
-- Support for custom memory allocators
-  (https://github.com/fmtlib/fmt/issues/69)
-
-- Formatting functions now accept [signed char]{.title-ref} and
-  [unsigned char]{.title-ref} strings as arguments
-  (https://github.com/fmtlib/fmt/issues/73):
-
-  ```c++
-  auto s = format("GLSL version: {}", glGetString(GL_VERSION));
-  ```
-
-- Reduced code bloat. According to the new [benchmark
-  results](https://github.com/fmtlib/fmt#compile-time-and-code-bloat),
-  cppformat is close to `printf` and by the order of magnitude better
-  than Boost Format in terms of compiled code size.
-
-- Improved appearance of the documentation on mobile by using the
-  [Sphinx Bootstrap
-  theme](http://ryan-roemer.github.io/sphinx-bootstrap-theme/):

-
-# 0.11.0 - 2014-08-21
-
-- Safe printf implementation with a POSIX extension for positional
-  arguments:
-
-  ```c++
-  fmt::printf("Elapsed time: %.2f seconds", 1.23);
-  fmt::printf("%1$s, %3$d %2$s", weekday, month, day);
-  ```
-
-- Arguments of `char` type can now be formatted as integers (Issue
-  https://github.com/fmtlib/fmt/issues/55):
-
-  ```c++
-  fmt::format("0x{0:02X}", 'a');
-  ```
-
-- Deprecated parts of the API removed.
-
-- The library is now built and tested on MinGW with Appveyor in
-  addition to existing test platforms Linux/GCC, OS X/Clang,
-  Windows/MSVC.
-
-# 0.10.0 - 2014-07-01
-
-**Improved API**
-
-- All formatting methods are now implemented as variadic functions
-  instead of using `operator<<` for feeding arbitrary arguments into a
-  temporary formatter object. This works both with C++11 where
-  variadic templates are used and with older standards where variadic
-  functions are emulated by providing lightweight wrapper functions
-  defined with the `FMT_VARIADIC` macro. You can use this macro for
-  defining your own portable variadic functions:
-
-  ```c++
-  void report_error(const char *format, const fmt::ArgList &args) {
-    fmt::print("Error: {}");
-    fmt::print(format, args);
-  }
-  FMT_VARIADIC(void, report_error, const char *)
-
-  report_error("file not found: {}", path);
-  ```
-
-  Apart from a more natural syntax, this also improves performance as
-  there is no need to construct temporary formatter objects and
-  control arguments\' lifetimes. Because the wrapper functions are
-  very lightweight, this doesn\'t cause code bloat even in pre-C++11
-  mode.
-
-- Simplified common case of formatting an `std::string`. Now it
-  requires a single function call:
-
-  ```c++
-  std::string s = format("The answer is {}.", 42);
-  ```
-
-  Previously it required 2 function calls:
-
-  ```c++
-  std::string s = str(Format("The answer is {}.") << 42);
-  ```
-
-  Instead of unsafe `c_str` function, `fmt::Writer` should be used
-  directly to bypass creation of `std::string`:
-
-  ```c++
-  fmt::Writer w;
-  w.write("The answer is {}.", 42);
-  w.c_str();  // returns a C string
-  ```
-
-  This doesn\'t do dynamic memory allocation for small strings and is
-  less error prone as the lifetime of the string is the same as for
-  `std::string::c_str` which is well understood (hopefully).
-
-- Improved consistency in naming functions that are a part of the
-  public API. Now all public functions are lowercase following the
-  standard library conventions. Previously it was a combination of
-  lowercase and CapitalizedWords. Issue
-  https://github.com/fmtlib/fmt/issues/50.
-
-- Old functions are marked as deprecated and will be removed in the
-  next release.
-
-**Other Changes**
-
-- Experimental support for printf format specifications (work in
-  progress):
-
-  ```c++
-  fmt::printf("The answer is %d.", 42);
-  std::string s = fmt::sprintf("Look, a %s!", "string");
-  ```
-
-- Support for hexadecimal floating point format specifiers `a` and
-  `A`:
-
-  ```c++
-  print("{:a}", -42.0); // Prints -0x1.5p+5
-  print("{:A}", -42.0); // Prints -0X1.5P+5
-  ```
-
-- CMake option `FMT_SHARED` that specifies whether to build format as
-  a shared library (off by default).
-
-# 0.9.0 - 2014-05-13
-
-- More efficient implementation of variadic formatting functions.
-
-- `Writer::Format` now has a variadic overload:
-
-  ```c++
-  Writer out;
-  out.Format("Look, I'm {}!", "variadic");
-  ```
-
-- For efficiency and consistency with other overloads, variadic
-  overload of the `Format` function now returns `Writer` instead of
-  `std::string`. Use the `str` function to convert it to
-  `std::string`:
-
-  ```c++
-  std::string s = str(Format("Look, I'm {}!", "variadic"));
-  ```
-
-- Replaced formatter actions with output sinks: `NoAction` -\>
-  `NullSink`, `Write` -\> `FileSink`, `ColorWriter` -\>
-  `ANSITerminalSink`. This improves naming consistency and shouldn\'t
-  affect client code unless these classes are used directly which
-  should be rarely needed.
-
-- Added `ThrowSystemError` function that formats a message and throws
-  `SystemError` containing the formatted message and system-specific
-  error description. For example, the following code
-
-  ```c++
-  FILE *f = fopen(filename, "r");
-  if (!f)
-    ThrowSystemError(errno, "Failed to open file '{}'") << filename;
-  ```
-
-  will throw `SystemError` exception with description \"Failed to open
-  file \'\<filename\>\': No such file or directory\" if file doesn\'t
-  exist.
-
-- Support for AppVeyor continuous integration platform.
-
-- `Format` now throws `SystemError` in case of I/O errors.
-
-- Improve test infrastructure. Print functions are now tested by
-  redirecting the output to a pipe.

+# 7.1.3 - 2020-11-24
+
+- Fixed handling of buffer boundaries in `format_to_n`
+  (https://github.com/fmtlib/fmt/issues/1996,
+  https://github.com/fmtlib/fmt/issues/2029).
+- Fixed linkage errors when linking with a shared library
+  (https://github.com/fmtlib/fmt/issues/2011).
+- Reintroduced ostream support to range formatters
+  (https://github.com/fmtlib/fmt/issues/2014).
+- Worked around an issue with mixing std versions in gcc
+  (https://github.com/fmtlib/fmt/issues/2017).
+
+# 7.1.2 - 2020-11-04
+
+- Fixed floating point formatting with large precision
+  (https://github.com/fmtlib/fmt/issues/1976).
+
+# 7.1.1 - 2020-11-01
+
+- Fixed ABI compatibility with 7.0.x
+  (https://github.com/fmtlib/fmt/issues/1961).
+- Added the `FMT_ARM_ABI_COMPATIBILITY` macro to work around ABI
+  incompatibility between GCC and Clang on ARM
+  (https://github.com/fmtlib/fmt/issues/1919).
+- Worked around a SFINAE bug in GCC 8
+  (https://github.com/fmtlib/fmt/issues/1957).
+- Fixed linkage errors when building with GCC\'s LTO
+  (https://github.com/fmtlib/fmt/issues/1955).
+- Fixed a compilation error when building without `__builtin_clz` or
+  equivalent (https://github.com/fmtlib/fmt/pull/1968).
+  Thanks @tohammer.
+- Fixed a sign conversion warning
+  (https://github.com/fmtlib/fmt/pull/1964). Thanks @OptoCloud.
+
+# 7.1.0 - 2020-10-25
+
+- Switched from
+  [Grisu3](https://www.cs.tufts.edu/~nr/cs257/archive/florian-loitsch/printf.pdf)
+  to [Dragonbox](https://github.com/jk-jeon/dragonbox) for the default
+  floating-point formatting which gives the shortest decimal
+  representation with round-trip guarantee and correct rounding
+  (https://github.com/fmtlib/fmt/pull/1882,
+  https://github.com/fmtlib/fmt/pull/1887,
+  https://github.com/fmtlib/fmt/pull/1894). This makes {fmt}
+  up to 20-30x faster than common implementations of
+  `std::ostringstream` and `sprintf` on
+  [dtoa-benchmark](https://github.com/fmtlib/dtoa-benchmark) and
+  faster than double-conversion and Ryū:
+
+  ![](https://user-images.githubusercontent.com/576385/95684665-11719600-0ba8-11eb-8e5b-972ff4e49428.png)
+
+  It is possible to get even better performance at the cost of larger
+  binary size by compiling with the `FMT_USE_FULL_CACHE_DRAGONBOX`
+  macro set to 1.
+
+  Thanks @jk-jeon.
+
+- Added an experimental unsynchronized file output API which, together
+  with [format string
+  compilation](https://fmt.dev/latest/api.html#compile-api), can give
+  [5-9 times speed up compared to
+  fprintf](https://www.zverovich.net/2020/08/04/optimal-file-buffer-size.html)
+  on common platforms ([godbolt](https://godbolt.org/z/nsTcG8)):
+
+  ```c++
+  #include <fmt/os.h>
+
+  int main() {
+    auto f = fmt::output_file("guide");
+    f.print("The answer is {}.", 42);
+  }
+  ```
+
+- Added a formatter for `std::chrono::time_point<system_clock>`
+  (https://github.com/fmtlib/fmt/issues/1819,
+  https://github.com/fmtlib/fmt/pull/1837). For example
+  ([godbolt](https://godbolt.org/z/c4M6fh)):
+
+  ```c++
+  #include <fmt/chrono.h>
+
+  int main() {
+    auto now = std::chrono::system_clock::now();
+    fmt::print("The time is {:%H:%M:%S}.\n", now);
+  }
+  ```
+
+  Thanks @adamburgess.
+
+- Added support for ranges with non-const `begin`/`end` to `fmt::join`
+  (https://github.com/fmtlib/fmt/issues/1784,
+  https://github.com/fmtlib/fmt/pull/1786). For example
+  ([godbolt](https://godbolt.org/z/jP63Tv)):
+
+  ```c++
+  #include <fmt/ranges.h>
+  #include <range/v3/view/filter.hpp>
+
+  int main() {
+    using std::literals::string_literals::operator""s;
+    auto strs = std::array{"a"s, "bb"s, "ccc"s};
+    auto range = strs | ranges::views::filter(
+      [] (const std::string &x) { return x.size() != 2; }
+    );
+    fmt::print("{}\n", fmt::join(range, ""));
+  }
+  ```
+
+  prints \"accc\".
+
+  Thanks @tonyelewis.
+
+- Added a `memory_buffer::append` overload that takes a range
+  (https://github.com/fmtlib/fmt/pull/1806). Thanks @BRevzin.
+
+- Improved handling of single code units in `FMT_COMPILE`. For
+  example:
+
+  ```c++
+  #include <fmt/compile.h>
+
+  char* f(char* buf) {
+    return fmt::format_to(buf, FMT_COMPILE("x{}"), 42);
+  }
+  ```
+
+  compiles to just ([godbolt](https://godbolt.org/z/5vncz3)):
+
+  ```asm
+  _Z1fPc:
+    movb $120, (%rdi)
+    xorl %edx, %edx
+    cmpl $42, _ZN3fmt2v76detail10basic_dataIvE23zero_or_powers_of_10_32E+8(%rip)
+    movl $3, %eax
+    seta %dl
+    subl %edx, %eax
+    movzwl _ZN3fmt2v76detail10basic_dataIvE6digitsE+84(%rip), %edx
+    cltq
+    addq %rdi, %rax
+    movw %dx, -2(%rax)
+    ret
+  ```
+
+  Here a single `mov` instruction writes `'x'` (`$120`) to the output
+  buffer.
+
+- Added dynamic width support to format string compilation
+  (https://github.com/fmtlib/fmt/issues/1809).
+
+- Improved error reporting for unformattable types: now you\'ll get
+  the type name directly in the error message instead of the note:
+
+  ```c++
+  #include <fmt/core.h>
+
+  struct how_about_no {};
+
+  int main() {
+    fmt::print("{}", how_about_no());
+  }
+  ```
+
+  Error ([godbolt](https://godbolt.org/z/GoxM4e)):
+
+  `fmt/core.h:1438:3: error: static_assert failed due to requirement 'fmt::v7::formattable<how_about_no>()' "Cannot format an argument. To make type T formattable provide a formatter<T> specialization: https://fmt.dev/latest/api.html#udt" ...`
+
+- Added the
+  [make_args_checked](https://fmt.dev/7.1.0/api.html#argument-lists)
+  function template that allows you to write formatting functions with
+  compile-time format string checks and avoid binary code bloat
+  ([godbolt](https://godbolt.org/z/PEf9qr)):
+
+  ```c++
+  void vlog(const char* file, int line, fmt::string_view format,
+            fmt::format_args args) {
+    fmt::print("{}: {}: ", file, line);
+    fmt::vprint(format, args);
+  }
+
+  template <typename S, typename... Args>
+  void log(const char* file, int line, const S& format, Args&&... args) {
+    vlog(file, line, format,
+        fmt::make_args_checked<Args...>(format, args...));
+  }
+
+  #define MY_LOG(format, ...) \
+    log(__FILE__, __LINE__, FMT_STRING(format), __VA_ARGS__)
+
+  MY_LOG("invalid squishiness: {}", 42);
+  ```
+
+- Replaced `snprintf` fallback with a faster internal IEEE 754 `float`
+  and `double` formatter for arbitrary precision. For example
+  ([godbolt](https://godbolt.org/z/dPhWvj)):
+
+  ```c++
+  #include <fmt/core.h>
+
+  int main() {
+    fmt::print("{:.500}\n", 4.9406564584124654E-324);
+  }
+  ```
+
+  prints
+
+  `4.9406564584124654417656879286822137236505980261432476442558568250067550727020875186529983636163599237979656469544571773092665671035593979639877479601078187812630071319031140452784581716784898210368871863605699873072305000638740915356498438731247339727316961514003171538539807412623856559117102665855668676818703956031062493194527159149245532930545654440112748012970999954193198940908041656332452475714786901472678015935523861155013480352649347201937902681071074917033322268447533357208324319360923829e-324`.
+
+- Made `format_to_n` and `formatted_size` part of the [core
+  API](https://fmt.dev/latest/api.html#core-api)
+  ([godbolt](https://godbolt.org/z/sPjY1K)):
+
+  ```c++
+  #include <fmt/core.h>
+
+  int main() {
+    char buffer[10];
+    auto result = fmt::format_to_n(buffer, sizeof(buffer), "{}", 42);
+  }
+  ```
+
+- Added `fmt::format_to_n` overload with format string compilation
+  (https://github.com/fmtlib/fmt/issues/1764,
+  https://github.com/fmtlib/fmt/pull/1767,
+  https://github.com/fmtlib/fmt/pull/1869). For example
+  ([godbolt](https://godbolt.org/z/93h86q)):
+
+  ```c++
+  #include <fmt/compile.h>
+
+  int main() {
+    char buffer[8];
+    fmt::format_to_n(buffer, sizeof(buffer), FMT_COMPILE("{}"), 42);
+  }
+  ```
+
+  Thanks @Kurkin and @alexezeder.
+
+- Added `fmt::format_to` overload that take `text_style`
+  (https://github.com/fmtlib/fmt/issues/1593,
+  https://github.com/fmtlib/fmt/issues/1842,
+  https://github.com/fmtlib/fmt/pull/1843). For example
+  ([godbolt](https://godbolt.org/z/91153r)):
+
+  ```c++
+  #include <fmt/color.h>
+
+  int main() {
+    std::string out;
+    fmt::format_to(std::back_inserter(out),
+                   fmt::emphasis::bold | fg(fmt::color::red),
+                   "The answer is {}.", 42);
+  }
+  ```
+
+  Thanks @Naios.
+
+- Made the `'#'` specifier emit trailing zeros in addition to the
+  decimal point (https://github.com/fmtlib/fmt/issues/1797).
+  For example ([godbolt](https://godbolt.org/z/bhdcW9)):
+
+  ```c++
+  #include <fmt/core.h>
+
+  int main() {
+    fmt::print("{:#.2g}", 0.5);
+  }
+  ```
+
+  prints `0.50`.
+
+- Changed the default floating point format to not include `.0` for
+  consistency with `std::format` and `std::to_chars`
+  (https://github.com/fmtlib/fmt/issues/1893,
+  https://github.com/fmtlib/fmt/issues/1943). It is possible
+  to get the decimal point and trailing zero with the `#` specifier.
+
+- Fixed an issue with floating-point formatting that could result in
+  addition of a non-significant trailing zero in rare cases e.g.
+  `1.00e-34` instead of `1.0e-34`
+  (https://github.com/fmtlib/fmt/issues/1873,
+  https://github.com/fmtlib/fmt/issues/1917).
+
+- Made `fmt::to_string` fallback on `ostream` insertion operator if
+  the `formatter` specialization is not provided
+  (https://github.com/fmtlib/fmt/issues/1815,
+  https://github.com/fmtlib/fmt/pull/1829). Thanks @alexezeder.
+
+- Added support for the append mode to the experimental file API and
+  improved `fcntl.h` detection.
+  (https://github.com/fmtlib/fmt/pull/1847,
+  https://github.com/fmtlib/fmt/pull/1848). Thanks @t-wiser.
+
+- Fixed handling of types that have both an implicit conversion
+  operator and an overloaded `ostream` insertion operator
+  (https://github.com/fmtlib/fmt/issues/1766).
+
+- Fixed a slicing issue in an internal iterator type
+  (https://github.com/fmtlib/fmt/pull/1822). Thanks @BRevzin.
+
+- Fixed an issue in locale-specific integer formatting
+  (https://github.com/fmtlib/fmt/issues/1927).
+
+- Fixed handling of exotic code unit types
+  (https://github.com/fmtlib/fmt/issues/1870,
+  https://github.com/fmtlib/fmt/issues/1932).
+
+- Improved `FMT_ALWAYS_INLINE`
+  (https://github.com/fmtlib/fmt/pull/1878). Thanks @jk-jeon.
+
+- Removed dependency on `windows.h`
+  (https://github.com/fmtlib/fmt/pull/1900). Thanks @bernd5.
+
+- Optimized counting of decimal digits on MSVC
+  (https://github.com/fmtlib/fmt/pull/1890). Thanks @mwinterb.
+
+- Improved documentation
+  (https://github.com/fmtlib/fmt/issues/1772,
+  https://github.com/fmtlib/fmt/pull/1775,
+  https://github.com/fmtlib/fmt/pull/1792,
+  https://github.com/fmtlib/fmt/pull/1838,
+  https://github.com/fmtlib/fmt/pull/1888,
+  https://github.com/fmtlib/fmt/pull/1918,
+  https://github.com/fmtlib/fmt/pull/1939).
+  Thanks @leolchat, @pepsiman, @Klaim, @ravijanjam, @francesco-st and @udnaan.
+
+- Added the `FMT_REDUCE_INT_INSTANTIATIONS` CMake option that reduces
+  the binary code size at the cost of some integer formatting
+  performance. This can be useful for extremely memory-constrained
+  embedded systems
+  (https://github.com/fmtlib/fmt/issues/1778,
+  https://github.com/fmtlib/fmt/pull/1781). Thanks @kammce.
+
+- Added the `FMT_USE_INLINE_NAMESPACES` macro to control usage of
+  inline namespaces
+  (https://github.com/fmtlib/fmt/pull/1945). Thanks @darklukee.
+
+- Improved build configuration
+  (https://github.com/fmtlib/fmt/pull/1760,
+  https://github.com/fmtlib/fmt/pull/1770,
+  https://github.com/fmtlib/fmt/issues/1779,
+  https://github.com/fmtlib/fmt/pull/1783,
+  https://github.com/fmtlib/fmt/pull/1823).
+  Thanks @dvetutnev, @xvitaly, @tambry, @medithe and @martinwuehrer.
+
+- Fixed various warnings and compilation issues
+  (https://github.com/fmtlib/fmt/pull/1790,
+  https://github.com/fmtlib/fmt/pull/1802,

+
+# 7.0.3 - 2020-08-06
+
+- Worked around broken `numeric_limits` for 128-bit integers
+  (https://github.com/fmtlib/fmt/issues/1787).
+- Added error reporting on missing named arguments
+  (https://github.com/fmtlib/fmt/issues/1796).
+- Stopped using 128-bit integers with clang-cl
+  (https://github.com/fmtlib/fmt/pull/1800). Thanks @Kingcom.
+- Fixed issues in locale-specific integer formatting
+  (https://github.com/fmtlib/fmt/issues/1782,
+  https://github.com/fmtlib/fmt/issues/1801).
+
+# 7.0.2 - 2020-07-29
+
+- Worked around broken `numeric_limits` for 128-bit integers
+  (https://github.com/fmtlib/fmt/issues/1725).
+- Fixed compatibility with CMake 3.4
+  (https://github.com/fmtlib/fmt/issues/1779).
+- Fixed handling of digit separators in locale-specific formatting
+  (https://github.com/fmtlib/fmt/issues/1782).
+
+# 7.0.1 - 2020-07-07
+
+- Updated the inline version namespace name.
+- Worked around a gcc bug in mangling of alias templates
+  (https://github.com/fmtlib/fmt/issues/1753).
+- Fixed a linkage error on Windows
+  (https://github.com/fmtlib/fmt/issues/1757). Thanks @Kurkin.
+- Fixed minor issues with the documentation.
+
+# 7.0.0 - 2020-07-05
+
+- Reduced the library size. For example, on macOS a stripped test
+  binary statically linked with {fmt} [shrank from \~368k to less than
+  100k](http://www.zverovich.net/2020/05/21/reducing-library-size.html).
+
+- Added a simpler and more efficient [format string compilation
+  API](https://fmt.dev/7.0.0/api.html#compile-api):
+
+  ```c++
+  #include <fmt/compile.h>
+
+  // Converts 42 into std::string using the most efficient method and no
+  // runtime format string processing.
+  std::string s = fmt::format(FMT_COMPILE("{}"), 42);
+  ```
+
+  The old `fmt::compile` API is now deprecated.
+
+- Optimized integer formatting: `format_to` with format string
+  compilation and a stack-allocated buffer is now [faster than
+  to_chars on both libc++ and
+  libstdc++](http://www.zverovich.net/2020/06/13/fast-int-to-string-revisited.html).
+
+- Optimized handling of small format strings. For example,
+
+  ```c++
+  fmt::format("Result: {}: ({},{},{},{})", str1, str2, str3, str4, str5)
+  ```
+
+  is now \~40% faster
+  (https://github.com/fmtlib/fmt/issues/1685).
+
+- Applied extern templates to improve compile times when using the
+  core API and `fmt/format.h`
+  (https://github.com/fmtlib/fmt/issues/1452). For example,
+  on macOS with clang the compile time of a test translation unit
+  dropped from 2.3s to 0.3s with `-O2` and from 0.6s to 0.3s with the
+  default settings (`-O0`).
+
+  Before (`-O2`):
+
+      % time c++ -c test.cc -I include -std=c++17 -O2
+      c++ -c test.cc -I include -std=c++17 -O2  2.22s user 0.08s system 99% cpu 2.311 total
+
+  After (`-O2`):
+
+      % time c++ -c test.cc -I include -std=c++17 -O2
+      c++ -c test.cc -I include -std=c++17 -O2  0.26s user 0.04s system 98% cpu 0.303 total
+
+  Before (default):
+
+      % time c++ -c test.cc -I include -std=c++17
+      c++ -c test.cc -I include -std=c++17  0.53s user 0.06s system 98% cpu 0.601 total
+
+  After (default):
+
+      % time c++ -c test.cc -I include -std=c++17
+      c++ -c test.cc -I include -std=c++17  0.24s user 0.06s system 98% cpu 0.301 total
+
+  It is still recommended to use `fmt/core.h` instead of
+  `fmt/format.h` but the compile time difference is now smaller.
+  Thanks @alex3d for the suggestion.
+
+- Named arguments are now stored on stack (no dynamic memory
+  allocations) and the compiled code is more compact and efficient.
+  For example
+
+  ```c++
+  #include <fmt/core.h>
+
+  int main() {
+    fmt::print("The answer is {answer}\n", fmt::arg("answer", 42));
+  }
+  ```
+
+  compiles to just ([godbolt](https://godbolt.org/z/NcfEp_))
+
+  ```asm
+  .LC0:
+          .string "answer"
+  .LC1:

+
+- Implemented compile-time checks for dynamic width and precision
+  (https://github.com/fmtlib/fmt/issues/1614):
+
+  ```c++
+  #include <fmt/format.h>
+
+  int main() {
+    fmt::print(FMT_STRING("{0:{1}}"), 42);
+  }
+  ```
+
+  now gives a compilation error because argument 1 doesn\'t exist:
+
+      In file included from test.cc:1:
+      include/fmt/format.h:2726:27: error: constexpr variable 'invalid_format' must be

+          if (id >= num_args_) on_error("argument not found");
+                              ^
+
+- Added sentinel support to `fmt::join`
+  (https://github.com/fmtlib/fmt/pull/1689)
+
+  ```c++
+  struct zstring_sentinel {};
+  bool operator==(const char* p, zstring_sentinel) { return *p == '\0'; }
+  bool operator!=(const char* p, zstring_sentinel) { return *p != '\0'; }
+
+  struct zstring {

+    const char* begin() const { return p; }
+    zstring_sentinel end() const { return {}; }
+  };
+
+  auto s = fmt::format("{}", fmt::join(zstring{"hello"}, "_"));
+  // s == "h_e_l_l_o"
+  ```
+
+  Thanks @BRevzin.
+
+- Added support for named arguments, `clear` and `reserve` to
+  `dynamic_format_arg_store`
+  (https://github.com/fmtlib/fmt/issues/1655,
+  https://github.com/fmtlib/fmt/pull/1663,
+  https://github.com/fmtlib/fmt/pull/1674,
+  https://github.com/fmtlib/fmt/pull/1677). Thanks @vsolontsov-ll.
+
+- Added support for the `'c'` format specifier to integral types for
+  compatibility with `std::format`
+  (https://github.com/fmtlib/fmt/issues/1652).
+
+- Replaced the `'n'` format specifier with `'L'` for compatibility
+  with `std::format`
+  (https://github.com/fmtlib/fmt/issues/1624). The `'n'`
+  specifier can be enabled via the `FMT_DEPRECATED_N_SPECIFIER` macro.
+
+- The `'='` format specifier is now disabled by default for
+  compatibility with `std::format`. It can be enabled via the
+  `FMT_DEPRECATED_NUMERIC_ALIGN` macro.
+
+- Removed the following deprecated APIs:
+
+  -   `FMT_STRING_ALIAS` and `fmt` macros - replaced by `FMT_STRING`
+  -   `fmt::basic_string_view::char_type` - replaced by
+      `fmt::basic_string_view::value_type`
+  -   `convert_to_int`
+  -   `format_arg_store::types`
+  -   `*parse_context` - replaced by `*format_parse_context`
+  -   `FMT_DEPRECATED_INCLUDE_OS`
+  -   `FMT_DEPRECATED_PERCENT` - incompatible with `std::format`
+  -   `*writer` - replaced by compiled format API
+
+- Renamed the `internal` namespace to `detail`
+  (https://github.com/fmtlib/fmt/issues/1538). The former is
+  still provided as an alias if the `FMT_USE_INTERNAL` macro is
+  defined.
+
+- Improved compatibility between `fmt::printf` with the standard specs
+  (https://github.com/fmtlib/fmt/issues/1595,
+  https://github.com/fmtlib/fmt/pull/1682,
+  https://github.com/fmtlib/fmt/pull/1683,
+  https://github.com/fmtlib/fmt/pull/1687,
+  https://github.com/fmtlib/fmt/pull/1699). Thanks @rimathia.
+
+- Fixed handling of `operator<<` overloads that use `copyfmt`
+  (https://github.com/fmtlib/fmt/issues/1666).
+
+- Added the `FMT_OS` CMake option to control inclusion of OS-specific
+  APIs in the fmt target. This can be useful for embedded platforms
+  (https://github.com/fmtlib/fmt/issues/1654,
+  https://github.com/fmtlib/fmt/pull/1656). Thanks @kwesolowski.
+
+- Replaced `FUZZING_BUILD_MODE_UNSAFE_FOR_PRODUCTION` with the
+  `FMT_FUZZ` macro to prevent interfering with fuzzing of projects
+  using {fmt} (https://github.com/fmtlib/fmt/pull/1650).
+  Thanks @asraa.
+
+- Fixed compatibility with emscripten
+  (https://github.com/fmtlib/fmt/issues/1636,
+  https://github.com/fmtlib/fmt/pull/1637). Thanks @ArthurSonzogni.
+
+- Improved documentation

+
+# 6.2.1 - 2020-05-09
+
+- Fixed ostream support in `sprintf`
+  (https://github.com/fmtlib/fmt/issues/1631).
+- Fixed type detection when using implicit conversion to `string_view`
+  and ostream `operator<<` inconsistently
+  (https://github.com/fmtlib/fmt/issues/1662).
+
+# 6.2.0 - 2020-04-05
+
+- Improved error reporting when trying to format an object of a
+  non-formattable type:
+
+  ```c++
+  fmt::format("{}", S());
+  ```
+
+  now gives:
+
+      include/fmt/core.h:1015:5: error: static_assert failed due to requirement
+      'formattable' "Cannot format argument. To make type T formattable provide a
+      formatter<T> specialization:
+      https://fmt.dev/latest/api.html#formatting-user-defined-types"
+          static_assert(
+          ^
+      ...
+      note: in instantiation of function template specialization
+      'fmt::v6::format<char [3], S, char>' requested here
+        fmt::format("{}", S());
+             ^
+
+  if `S` is not formattable.
+
+- Reduced the library size by \~10%.
+
+- Always print decimal point if `#` is specified
+  (https://github.com/fmtlib/fmt/issues/1476,
+  https://github.com/fmtlib/fmt/issues/1498):
+
+  ```c++
+  fmt::print("{:#.0f}", 42.0);
+  ```
+
+  now prints `42.`
+
+- Implemented the `'L'` specifier for locale-specific numeric
+  formatting to improve compatibility with `std::format`. The `'n'`
+  specifier is now deprecated and will be removed in the next major
+  release.
+
+- Moved OS-specific APIs such as `windows_error` from `fmt/format.h`
+  to `fmt/os.h`. You can define `FMT_DEPRECATED_INCLUDE_OS` to
+  automatically include `fmt/os.h` from `fmt/format.h` for
+  compatibility but this will be disabled in the next major release.
+
+- Added precision overflow detection in floating-point formatting.
+
+- Implemented detection of invalid use of `fmt::arg`.
+
+- Used `type_identity` to block unnecessary template argument
+  deduction. Thanks Tim Song.
+
+- Improved UTF-8 handling
+  (https://github.com/fmtlib/fmt/issues/1109):
+
+  ```c++
+  fmt::print("┌{0:─^{2}}┐\n"
+             "│{1: ^{2}}│\n"
+             "└{0:─^{2}}┘\n", "", "Прывітанне, свет!", 21);
+  ```
+
+  now prints:
+
+      ┌─────────────────────┐
+      │  Прывітанне, свет!  │
+      └─────────────────────┘
+
+  on systems that support Unicode.
+
+- Added experimental dynamic argument storage
+  (https://github.com/fmtlib/fmt/issues/1170,
+  https://github.com/fmtlib/fmt/pull/1584):
+
+  ```c++
+  fmt::dynamic_format_arg_store<fmt::format_context> store;
+  store.push_back("answer");
+  store.push_back(42);
+  fmt::vprint("The {} is {}.\n", store);
+  ```
+
+  prints:
+
+      The answer is 42.
+
+  Thanks @vsolontsov-ll.
+
+- Made `fmt::join` accept `initializer_list`
+  (https://github.com/fmtlib/fmt/pull/1591). Thanks @Rapotkinnik.
+
+- Fixed handling of empty tuples
+  (https://github.com/fmtlib/fmt/issues/1588).
+
+- Fixed handling of output iterators in `format_to_n`
+  (https://github.com/fmtlib/fmt/issues/1506).
+
+- Fixed formatting of `std::chrono::duration` types to wide output
+  (https://github.com/fmtlib/fmt/pull/1533). Thanks @zeffy.
+
+- Added const `begin` and `end` overload to buffers
+  (https://github.com/fmtlib/fmt/pull/1553). Thanks @dominicpoeschko.
+
+- Added the ability to disable floating-point formatting via
+  `FMT_USE_FLOAT`, `FMT_USE_DOUBLE` and `FMT_USE_LONG_DOUBLE` macros
+  for extremely memory-constrained embedded system
+  (https://github.com/fmtlib/fmt/pull/1590). Thanks @albaguirre.
+
+- Made `FMT_STRING` work with `constexpr` `string_view`
+  (https://github.com/fmtlib/fmt/pull/1589). Thanks @scramsby.
+
+- Implemented a minor optimization in the format string parser
+  (https://github.com/fmtlib/fmt/pull/1560). Thanks @IkarusDeveloper.
+
+- Improved attribute detection
+  (https://github.com/fmtlib/fmt/pull/1469,

+
+# 6.1.2 - 2019-12-11
+
+- Fixed ABI compatibility with `libfmt.so.6.0.0`
+  (https://github.com/fmtlib/fmt/issues/1471).
+- Fixed handling types convertible to `std::string_view`
+  (https://github.com/fmtlib/fmt/pull/1451). Thanks @denizevrenci.
+- Made CUDA test an opt-in enabled via the `FMT_CUDA_TEST` CMake
+  option.
+- Fixed sign conversion warnings
+  (https://github.com/fmtlib/fmt/pull/1440). Thanks @0x8000-0000.
+
+# 6.1.1 - 2019-12-04
+
+- Fixed shared library build on Windows
+  (https://github.com/fmtlib/fmt/pull/1443,
+  https://github.com/fmtlib/fmt/issues/1445,
+  https://github.com/fmtlib/fmt/pull/1446,
+  https://github.com/fmtlib/fmt/issues/1450).
+  Thanks @egorpugin and @bbolli.
+- Added a missing decimal point in exponent notation with trailing
+  zeros.
+- Removed deprecated `format_arg_store::TYPES`.
+
+# 6.1.0 - 2019-12-01
+
+- {fmt} now formats IEEE 754 `float` and `double` using the shortest
+  decimal representation with correct rounding by default:
+
+  ```c++
+  #include <cmath>
+  #include <fmt/core.h>
+
+  int main() {
+    fmt::print("{}", M_PI);
+  }
+  ```
+
+  prints `3.141592653589793`.
+
+- Made the fast binary to decimal floating-point formatter the
+  default, simplified it and improved performance. {fmt} is now 15
+  times faster than libc++\'s `std::ostringstream`, 11 times faster
+  than `printf` and 10% faster than double-conversion on
+  [dtoa-benchmark](https://github.com/fmtlib/dtoa-benchmark):
+
+  | Function      | Time (ns) | Speedup |
+  | ------------- | --------: | ------: |
+  | ostringstream | 1,346.30  | 1.00x   |
+  | ostrstream    | 1,195.74  | 1.13x   |
+  | sprintf       | 995.08    | 1.35x   |
+  | doubleconv    | 99.10     | 13.59x  |
+  | fmt           | 88.34     | 15.24x  |

+  ![](https://user-images.githubusercontent.com/576385/69767160-cdaca400-112f-11ea-9fc5-347c9f83caad.png)
+
+- {fmt} no longer converts `float` arguments to `double`. In
+  particular this improves the default (shortest) representation of
+  floats and makes `fmt::format` consistent with `std::format` specs
+  (https://github.com/fmtlib/fmt/issues/1336,
+  https://github.com/fmtlib/fmt/issues/1353,
+  https://github.com/fmtlib/fmt/pull/1360,
+  https://github.com/fmtlib/fmt/pull/1361):
+
+  ```c++
+  fmt::print("{}", 0.1f);
+  ```
+
+  prints `0.1` instead of `0.10000000149011612`.
+
+  Thanks @orivej.
+
+- Made floating-point formatting output consistent with
+  `printf`/iostreams
+  (https://github.com/fmtlib/fmt/issues/1376,
+  https://github.com/fmtlib/fmt/issues/1417).
+
+- Added support for 128-bit integers
+  (https://github.com/fmtlib/fmt/pull/1287):
+
+  ```c++
+  fmt::print("{}", std::numeric_limits<__int128_t>::max());
+  ```
+
+  prints `170141183460469231731687303715884105727`.
+
+  Thanks @denizevrenci.
+
+- The overload of `print` that takes `text_style` is now atomic, i.e.
+  the output from different threads doesn\'t interleave
+  (https://github.com/fmtlib/fmt/pull/1351). Thanks @tankiJong.
+
+- Made compile time in the header-only mode \~20% faster by reducing
+  the number of template instantiations. `wchar_t` overload of
+  `vprint` was moved from `fmt/core.h` to `fmt/format.h`.
+
+- Added an overload of `fmt::join` that works with tuples
+  (https://github.com/fmtlib/fmt/issues/1322,
+  https://github.com/fmtlib/fmt/pull/1330):
+
+  ```c++
+  #include <tuple>
+  #include <fmt/ranges.h>
+
+  int main() {
+    std::tuple<char, int, float> t{'a', 1, 2.0f};
+    fmt::print("{}", t);
+  }
+  ```
+
+  prints `('a', 1, 2.0)`.
+
+  Thanks @jeremyong.
+
+- Changed formatting of octal zero with prefix from \"00\" to \"0\":
+
+  ```c++
+  fmt::print("{:#o}", 0);
+  ```
+
+  prints `0`.
+
+- The locale is now passed to ostream insertion (`<<`) operators
+  (https://github.com/fmtlib/fmt/pull/1406):
+
+  ```c++
+  #include <fmt/locale.h>
+  #include <fmt/ostream.h>
+
+  struct S {
+    double value;
+  };
+
+  std::ostream& operator<<(std::ostream& os, S s) {
+    return os << s.value;
+  }
+
+  int main() {
+    auto s = fmt::format(std::locale("fr_FR.UTF-8"), "{}", S{0.42});
+    // s == "0,42"
+  }
+  ```
+
+  Thanks @dlaugt.
+
+- Locale-specific number formatting now uses grouping
+  (https://github.com/fmtlib/fmt/issues/1393,
+  https://github.com/fmtlib/fmt/pull/1394). Thanks @skrdaniel.
+
+- Fixed handling of types with deleted implicit rvalue conversion to
+  `const char**` (https://github.com/fmtlib/fmt/issues/1421):
+
+  ```c++
+  struct mystring {
+    operator const char*() const&;
+    operator const char*() &;
+    operator const char*() const&& = delete;
+    operator const char*() && = delete;
+  };
+  mystring str;
+  fmt::print("{}", str); // now compiles
+  ```
+
+- Enums are now mapped to correct underlying types instead of `int`
+  (https://github.com/fmtlib/fmt/pull/1286). Thanks @agmt.
+
+- Enum classes are no longer implicitly converted to `int`
+  (https://github.com/fmtlib/fmt/issues/1424).
+
+- Added `basic_format_parse_context` for consistency with C++20
+  `std::format` and deprecated `basic_parse_context`.
+
+- Fixed handling of UTF-8 in precision
+  (https://github.com/fmtlib/fmt/issues/1389,
+  https://github.com/fmtlib/fmt/pull/1390). Thanks @tajtiattila.
+
+- {fmt} can now be installed on Linux, macOS and Windows with
+  [Conda](https://docs.conda.io/en/latest/) using its
+  [conda-forge](https://conda-forge.org)
+  [package](https://github.com/conda-forge/fmt-feedstock)
+  (https://github.com/fmtlib/fmt/pull/1410):
+
+      conda install -c conda-forge fmt
+
+  Thanks @tdegeus.
+
+- Added a CUDA test (https://github.com/fmtlib/fmt/pull/1285,
+  https://github.com/fmtlib/fmt/pull/1317).
+  Thanks @luncliff and @risa2000.
+

+  Thanks @orivej and @dpacbach.
+
+- Fixed compile-time format string checks for user-defined types
+  (https://github.com/fmtlib/fmt/issues/1292).
+
+- Worked around a false positive in `unsigned-integer-overflow` sanitizer
+  (https://github.com/fmtlib/fmt/issues/1377).

+
+# 6.0.0 - 2019-08-26
+
+- Switched to the [MIT license](
+  https://github.com/fmtlib/fmt/blob/5a4b24613ba16cc689977c3b5bd8274a3ba1dd1f/LICENSE.rst)
+  with an optional exception that allows distributing binary code
+  without attribution.
+
+- Floating-point formatting is now locale-independent by default:
+
+  ```c++
+  #include <locale>
+  #include <fmt/core.h>
+
+  int main() {
+    std::locale::global(std::locale("ru_RU.UTF-8"));
+    fmt::print("value = {}", 4.2);
+  }
+  ```
+
+  prints \"value = 4.2\" regardless of the locale.
+
+  For locale-specific formatting use the `n` specifier:
+
+  ```c++
+  std::locale::global(std::locale("ru_RU.UTF-8"));
+  fmt::print("value = {:n}", 4.2);
+  ```
+
+  prints \"value = 4,2\".
+
+- Added an experimental Grisu floating-point formatting algorithm
+  implementation (disabled by default). To enable it compile with the
+  `FMT_USE_GRISU` macro defined to 1:
+
+  ```c++
+  #define FMT_USE_GRISU 1
+  #include <fmt/format.h>
+
+  auto s = fmt::format("{}", 4.2); // formats 4.2 using Grisu
+  ```
+
+  With Grisu enabled, {fmt} is 13x faster than `std::ostringstream`
+  (libc++) and 10x faster than `sprintf` on
+  [dtoa-benchmark](https://github.com/fmtlib/dtoa-benchmark) ([full
+  results](https://fmt.dev/unknown_mac64_clang10.0.html)):
+
+  ![](https://user-images.githubusercontent.com/576385/54883977-9fe8c000-4e28-11e9-8bde-272d122e7c52.jpg)
+
+- Separated formatting and parsing contexts for consistency with
+  [C++20 std::format](http://eel.is/c++draft/format), removing the
+  undocumented `basic_format_context::parse_context()` function.
+
+- Added [oss-fuzz](https://github.com/google/oss-fuzz) support
+  (https://github.com/fmtlib/fmt/pull/1199). Thanks @pauldreik.
+
+- `formatter` specializations now always take precedence over
+  `operator<<` (https://github.com/fmtlib/fmt/issues/952):
+
+  ```c++
+  #include <iostream>
+  #include <fmt/ostream.h>
+
+  struct S {};
+
+  std::ostream& operator<<(std::ostream& os, S) {
+    return os << 1;
+  }
+
+  template <>
+  struct fmt::formatter<S> : fmt::formatter<int> {
+    auto format(S, format_context& ctx) {
+      return formatter<int>::format(2, ctx);
+    }
+  };
+
+  int main() {
+    std::cout << S() << "\n"; // prints 1 using operator<<
+    fmt::print("{}\n", S());  // prints 2 using formatter
+  }
+  ```
+
+- Introduced the experimental `fmt::compile` function that does format
+  string compilation
+  (https://github.com/fmtlib/fmt/issues/618,
+  https://github.com/fmtlib/fmt/issues/1169,
+  https://github.com/fmtlib/fmt/pull/1171):
+
+  ```c++
+  #include <fmt/compile.h>
+
+  auto f = fmt::compile<int>("{}");
+  std::string s = fmt::format(f, 42); // can be called multiple times to
+                                      // format different values
+  // s == "42"
+  ```
+
+  It moves the cost of parsing a format string outside of the format
+  function which can be beneficial when identically formatting many
+  objects of the same types. Thanks @stryku.
+
+- Added experimental `%` format specifier that formats floating-point
+  values as percentages
+  (https://github.com/fmtlib/fmt/pull/1060,
+  https://github.com/fmtlib/fmt/pull/1069,
+  https://github.com/fmtlib/fmt/pull/1071):
+
+  ```c++
+  auto s = fmt::format("{:.1%}", 0.42); // s == "42.0%"
+  ```
+
+  Thanks @gawain-bolton.
+
+- Implemented precision for floating-point durations
+  (https://github.com/fmtlib/fmt/issues/1004,
+  https://github.com/fmtlib/fmt/pull/1012):
+
+  ```c++
+  auto s = fmt::format("{:.1}", std::chrono::duration<double>(1.234));
+  // s == 1.2s
+  ```
+
+  Thanks @DanielaE.
+
+- Implemented `chrono` format specifiers `%Q` and `%q` that give the
+  value and the unit respectively
+  (https://github.com/fmtlib/fmt/pull/1019):
+
+  ```c++
+  auto value = fmt::format("{:%Q}", 42s); // value == "42"
+  auto unit  = fmt::format("{:%q}", 42s); // unit == "s"
+  ```
+
+  Thanks @DanielaE.
+
+- Fixed handling of dynamic width in chrono formatter:
+
+  ```c++
+  auto s = fmt::format("{0:{1}%H:%M:%S}", std::chrono::seconds(12345), 12);
+  //                        ^ width argument index                     ^ width
+  // s == "03:25:45    "
+  ```
+
+  Thanks Howard Hinnant.
+
+- Removed deprecated `fmt/time.h`. Use `fmt/chrono.h` instead.
+
+- Added `fmt::format` and `fmt::vformat` overloads that take
+  `text_style` (https://github.com/fmtlib/fmt/issues/993,
+  https://github.com/fmtlib/fmt/pull/994):
+
+  ```c++
+  #include <fmt/color.h>
+
+  std::string message = fmt::format(fmt::emphasis::bold | fg(fmt::color::red),
+                                    "The answer is {}.", 42);
+  ```
+
+  Thanks @Naios.
+
+- Removed the deprecated color API (`print_colored`). Use the new API,
+  namely `print` overloads that take `text_style` instead.
+
+- Made `std::unique_ptr` and `std::shared_ptr` formattable as pointers
+  via `fmt::ptr` (https://github.com/fmtlib/fmt/pull/1121):
+
+  ```c++
+  std::unique_ptr<int> p = ...;
+  fmt::print("{}", fmt::ptr(p)); // prints p as a pointer
+  ```
+
+  Thanks @sighingnow.
+
+- Made `print` and `vprint` report I/O errors
+  (https://github.com/fmtlib/fmt/issues/1098,
+  https://github.com/fmtlib/fmt/pull/1099). Thanks @BillyDonahue.
+
+- Marked deprecated APIs with the `[[deprecated]]` attribute and
+  removed internal uses of deprecated APIs
+  (https://github.com/fmtlib/fmt/pull/1022). Thanks @eliaskosunen.
+
+- Modernized the codebase using more C++11 features and removing
+  workarounds. Most importantly, `buffer_context` is now an alias
+  template, so use `buffer_context<T>` instead of
+  `buffer_context<T>::type`. These features require GCC 4.8 or later.
+
+- `formatter` specializations now always take precedence over implicit
+  conversions to `int` and the undocumented `convert_to_int` trait is
+  now deprecated.
+
+- Moved the undocumented `basic_writer`, `writer`, and `wwriter` types
+  to the `internal` namespace.
+
+- Removed deprecated `basic_format_context::begin()`. Use `out()`
+  instead.
+
+- Disallowed passing the result of `join` as an lvalue to prevent
+  misuse.
+
+- Refactored the undocumented structs that represent parsed format
+  specifiers to simplify the API and allow multibyte fill.
+
+- Moved SFINAE to template parameters to reduce symbol sizes.
+
+- Switched to `fputws` for writing wide strings so that it\'s no
+  longer required to call `_setmode` on Windows
+  (https://github.com/fmtlib/fmt/issues/1229,
+  https://github.com/fmtlib/fmt/pull/1243). Thanks @jackoalan.
+
+- Improved literal-based API
+  (https://github.com/fmtlib/fmt/pull/1254). Thanks @sylveon.
+
+- Added support for exotic platforms without `uintptr_t` such as IBM i
+  (AS/400) which has 128-bit pointers and only 64-bit integers
+  (https://github.com/fmtlib/fmt/issues/1059).
+
+- Added [Sublime Text syntax highlighting config](
+  https://github.com/fmtlib/fmt/blob/master/support/C%2B%2B.sublime-syntax)
+  (https://github.com/fmtlib/fmt/issues/1037). Thanks @Kronuz.
+
+- Added the `FMT_ENFORCE_COMPILE_STRING` macro to enforce the use of
+  compile-time format strings
+  (https://github.com/fmtlib/fmt/pull/1231). Thanks @jackoalan.
+
+- Stopped setting `CMAKE_BUILD_TYPE` if {fmt} is a subproject
+  (https://github.com/fmtlib/fmt/issues/1081).
+
+- Various build improvements
+  (https://github.com/fmtlib/fmt/pull/1039,

+  Thanks @mikelui, @foonathan, @BillyDonahue, @jwakely, @kaisbe and
+  @sdebionne.
+
+- Fixed ambiguous formatter specialization in `fmt/ranges.h`
+  (https://github.com/fmtlib/fmt/issues/1123).
+
+- Fixed formatting of a non-empty `std::filesystem::path` which is an
+  infinitely deep range of its components
+  (https://github.com/fmtlib/fmt/issues/1268).
+
+- Fixed handling of general output iterators when formatting
+  characters (https://github.com/fmtlib/fmt/issues/1056,
+  https://github.com/fmtlib/fmt/pull/1058). Thanks @abolz.
+

+  https://github.com/fmtlib/fmt/pull/1147). Thanks @denchat.
+
+- Disabled the use of UDL template extension on GCC 9
+  (https://github.com/fmtlib/fmt/issues/1148).
+
+- Removed misplaced `format` compile-time checks from `printf`
+  (https://github.com/fmtlib/fmt/issues/1173).
+
+- Fixed issues in the experimental floating-point formatter
+  (https://github.com/fmtlib/fmt/issues/1072,

+
+# 5.3.0 - 2018-12-28
+
+- Introduced experimental chrono formatting support:
+
+  ```c++
+  #include <fmt/chrono.h>
+
+  int main() {
+    using namespace std::literals::chrono_literals;
+    fmt::print("Default format: {} {}\n", 42s, 100ms);
+    fmt::print("strftime-like format: {:%H:%M:%S}\n", 3h + 15min + 30s);
+  }
+  ```
+
+  prints:
+
+      Default format: 42s 100ms
+      strftime-like format: 03:15:30
+
+- Added experimental support for emphasis (bold, italic, underline,
+  strikethrough), colored output to a file stream, and improved
+  colored formatting API
+  (https://github.com/fmtlib/fmt/pull/961,
+  https://github.com/fmtlib/fmt/pull/967,
+  https://github.com/fmtlib/fmt/pull/973):
+
+  ```c++
+  #include <fmt/color.h>
+
+  int main() {
+    fmt::print(fg(fmt::color::crimson) | fmt::emphasis::bold,
+               "Hello, {}!\n", "world");
+    fmt::print(fg(fmt::color::floral_white) | bg(fmt::color::slate_gray) |
+               fmt::emphasis::underline, "Olá, {}!\n", "Mundo");
+    fmt::print(fg(fmt::color::steel_blue) | fmt::emphasis::italic,
+               "你好{}！\n", "世界");
+  }
+  ```
+
+  prints the following on modern terminals with RGB color support:

+
+  Thanks @Rakete1111.
+
+- Added support for 4-bit terminal colors
+  (https://github.com/fmtlib/fmt/issues/968,
+  https://github.com/fmtlib/fmt/pull/974)
+
+  ```c++
+  #include <fmt/color.h>
+
+  int main() {
+    print(fg(fmt::terminal_color::red), "stop\n");
+  }
+  ```
+
+  Note that these colors vary by terminal:

+  ![](https://user-images.githubusercontent.com/576385/50405925-dbfc7e00-0770-11e9-9b85-333fab0af9ac.png)
+
+  Thanks @Rakete1111.
+
+- Parameterized formatting functions on the type of the format string
+  (https://github.com/fmtlib/fmt/issues/880,
+  https://github.com/fmtlib/fmt/pull/881,
+  https://github.com/fmtlib/fmt/pull/883,
+  https://github.com/fmtlib/fmt/pull/885,
+  https://github.com/fmtlib/fmt/pull/897,
+  https://github.com/fmtlib/fmt/issues/920). Any object of
+  type `S` that has an overloaded `to_string_view(const S&)` returning
+  `fmt::string_view` can be used as a format string:
+
+  ```c++
+  namespace my_ns {
+  inline string_view to_string_view(const my_string& s) {
+    return {s.data(), s.length()};
+  }
+  }
+
+  std::string message = fmt::format(my_string("The answer is {}."), 42);
+  ```
+
+  Thanks @DanielaE.
+
+- Made `std::string_view` work as a format string
+  (https://github.com/fmtlib/fmt/pull/898):
+
+  ```c++
+  auto message = fmt::format(std::string_view("The answer is {}."), 42);
+  ```
+
+  Thanks @DanielaE.
+
+- Added wide string support to compile-time format string checks
+  (https://github.com/fmtlib/fmt/pull/924):
+
+  ```c++
+  print(fmt(L"{:f}"), 42); // compile-time error: invalid type specifier
+  ```
+
+  Thanks @XZiar.
+
+- Made colored print functions work with wide strings
+  (https://github.com/fmtlib/fmt/pull/867):
+
+  ```c++
+  #include <fmt/color.h>
+
+  int main() {
+    print(fg(fmt::color::red), L"{}\n", 42);
+  }
+  ```
+
+  Thanks @DanielaE.
+
+- Introduced experimental Unicode support
+  (https://github.com/fmtlib/fmt/issues/628,
+  https://github.com/fmtlib/fmt/pull/891):
+
+  ```c++
+  using namespace fmt::literals;
+  auto s = fmt::format("{:*^5}"_u, "🤡"_u); // s == "**🤡**"_u
+  ```
+
+- Improved locale support:
+
+  ```c++
+  #include <fmt/locale.h>
+
+  struct numpunct : std::numpunct<char> {
+   protected:
+    char do_thousands_sep() const override { return '~'; }
+  };
+
+  std::locale loc;
+  auto s = fmt::format(std::locale(loc, new numpunct()), "{:n}", 1234567);
+  // s == "1~234~567"
+  ```
+
+- Constrained formatting functions on proper iterator types
+  (https://github.com/fmtlib/fmt/pull/921). Thanks @DanielaE.
+
+- Added `make_printf_args` and `make_wprintf_args` functions
+  (https://github.com/fmtlib/fmt/pull/934). Thanks @tnovotny.
+
+- Deprecated `fmt::visit`, `parse_context`, and `wparse_context`. Use
+  `fmt::visit_format_arg`, `format_parse_context`, and
+  `wformat_parse_context` instead.
+
+- Removed undocumented `basic_fixed_buffer` which has been superseded
+  by the iterator-based API
+  (https://github.com/fmtlib/fmt/issues/873,
+  https://github.com/fmtlib/fmt/pull/902). Thanks @superfunc.
+
+- Disallowed repeated leading zeros in an argument ID:
+
+  ```c++
+  fmt::print("{000}", 42); // error
+  ```
+
+- Reintroduced support for gcc 4.4.
+
+- Fixed compilation on platforms with exotic `double`
+  (https://github.com/fmtlib/fmt/issues/878).
+
+- Improved documentation
+  (https://github.com/fmtlib/fmt/issues/164,
+  https://github.com/fmtlib/fmt/issues/877,
+  https://github.com/fmtlib/fmt/pull/901,
+  https://github.com/fmtlib/fmt/pull/906,
+  https://github.com/fmtlib/fmt/pull/979).
+  Thanks @kookjr, @DarkDimius and @HecticSerenity.
+
+- Added pkgconfig support which makes it easier to consume the library
+  from meson and other build systems
+  (https://github.com/fmtlib/fmt/pull/916). Thanks @colemickens.
+
+- Various build improvements
+  (https://github.com/fmtlib/fmt/pull/909,
+  https://github.com/fmtlib/fmt/pull/926,
+  https://github.com/fmtlib/fmt/pull/937,
+  https://github.com/fmtlib/fmt/pull/953,
+  https://github.com/fmtlib/fmt/pull/959).
+  Thanks @tchaikov, @luncliff, @AndreasSchoenle, @hotwatermorning and @Zefz.
+
+- Improved `string_view` construction performance
+  (https://github.com/fmtlib/fmt/pull/914). Thanks @gabime.
+
+- Fixed non-matching char types
+  (https://github.com/fmtlib/fmt/pull/895). Thanks @DanielaE.
+
+- Fixed `format_to_n` with `std::back_insert_iterator`
+  (https://github.com/fmtlib/fmt/pull/913). Thanks @DanielaE.
+
+- Fixed locale-dependent formatting
+  (https://github.com/fmtlib/fmt/issues/905).
+
+- Fixed various compiler warnings and errors
+  (https://github.com/fmtlib/fmt/pull/882,
+  https://github.com/fmtlib/fmt/pull/886,

+  Thanks @Luthaf, @stevenhoving, @christinaa, @lgritz, @DanielaE,
+  @0x8000-0000 and @liuping1997.
+
+# 5.2.1 - 2018-09-21
+
+- Fixed `visit` lookup issues on gcc 7 & 8
+  (https://github.com/fmtlib/fmt/pull/870). Thanks @medithe.
+- Fixed linkage errors on older gcc.
+- Prevented `fmt/range.h` from specializing `fmt::basic_string_view`
+  (https://github.com/fmtlib/fmt/issues/865,
+  https://github.com/fmtlib/fmt/pull/868). Thanks @hhggit.
+- Improved error message when formatting unknown types
+  (https://github.com/fmtlib/fmt/pull/872). Thanks @foonathan.
+- Disabled templated user-defined literals when compiled under nvcc
+  (https://github.com/fmtlib/fmt/pull/875). Thanks @CandyGumdrop.
+- Fixed `format_to` formatting to `wmemory_buffer`
+  (https://github.com/fmtlib/fmt/issues/874).
+
+# 5.2.0 - 2018-09-13
+
+- Optimized format string parsing and argument processing which
+  resulted in up to 5x speed up on long format strings and significant
+  performance boost on various benchmarks. For example, version 5.2 is
+  2.22x faster than 5.1 on decimal integer formatting with `format_to`
+  (macOS, clang-902.0.39.2):
+
+  | Method                     | Time, s         | Speedup |
+  | -------------------------- | --------------: | ------: |
+  | fmt::format 5.1            | 0.58            |         |
+  | fmt::format 5.2            | 0.35            |   1.66x |
+  | fmt::format_to 5.1         | 0.51            |         |
+  | fmt::format_to 5.2         | 0.23            |   2.22x |
+  | sprintf                    | 0.71            |         |
+  | std::to_string             | 1.01            |         |
+  | std::stringstream          | 1.73            |         |
+
+- Changed the `fmt` macro from opt-out to opt-in to prevent name
+  collisions. To enable it define the `FMT_STRING_ALIAS` macro to 1
+  before including `fmt/format.h`:
+
+  ```c++
+  #define FMT_STRING_ALIAS 1
+  #include <fmt/format.h>
+  std::string answer = format(fmt("{}"), 42);
+  ```
+
+- Added compile-time format string checks to `format_to` overload that
+  takes `fmt::memory_buffer`
+  (https://github.com/fmtlib/fmt/issues/783):
+
+  ```c++
+  fmt::memory_buffer buf;
+  // Compile-time error: invalid type specifier.
+  fmt::format_to(buf, fmt("{:d}"), "foo");
+  ```
+
+- Moved experimental color support to `fmt/color.h` and enabled the
+  new API by default. The old API can be enabled by defining the
+  `FMT_DEPRECATED_COLORS` macro.
+
+- Added formatting support for types explicitly convertible to
+  `fmt::string_view`:
+
+  ```c++
+  struct foo {
+    explicit operator fmt::string_view() const { return "foo"; }
+  };
+  auto s = format("{}", foo());
+  ```
+
+  In particular, this makes formatting function work with
+  `folly::StringPiece`.
+
+- Implemented preliminary support for `char*_t` by replacing the
+  `format` function overloads with a single function template
+  parameterized on the string type.
+
+- Added support for dynamic argument lists
+  (https://github.com/fmtlib/fmt/issues/814,
+  https://github.com/fmtlib/fmt/pull/819). Thanks @MikePopoloski.
+
+- Reduced executable size overhead for embedded targets using newlib
+  nano by making locale dependency optional
+  (https://github.com/fmtlib/fmt/pull/839). Thanks @teajay-fr.
+
+- Keep `noexcept` specifier when exceptions are disabled
+  (https://github.com/fmtlib/fmt/issues/801,
+  https://github.com/fmtlib/fmt/pull/810). Thanks @qis.
+
+- Fixed formatting of user-defined types providing `operator<<` with
+  `format_to_n` (https://github.com/fmtlib/fmt/pull/806).
+  Thanks @mkurdej.
+
+- Fixed dynamic linkage of new symbols
+  (https://github.com/fmtlib/fmt/issues/808).
+
+- Fixed global initialization issue
+  (https://github.com/fmtlib/fmt/issues/807):
+
+  ```c++
+  // This works on compilers with constexpr support.
+  static const std::string answer = fmt::format("{}", 42);
+  ```
+
+- Fixed various compiler warnings and errors
+  (https://github.com/fmtlib/fmt/pull/804,
+  https://github.com/fmtlib/fmt/issues/809,
+  https://github.com/fmtlib/fmt/pull/811,
+  https://github.com/fmtlib/fmt/issues/822,

+  https://github.com/fmtlib/fmt/issues/851,
+  https://github.com/fmtlib/fmt/pull/852,
+  https://github.com/fmtlib/fmt/pull/854).
+  Thanks @henryiii, @medithe, and @eliasdaler.
+
+# 5.1.0 - 2018-07-05
+
+- Added experimental support for RGB color output enabled with the
+  `FMT_EXTENDED_COLORS` macro:
+
+  ```c++
+  #define FMT_EXTENDED_COLORS
+  #define FMT_HEADER_ONLY // or compile fmt with FMT_EXTENDED_COLORS defined
+  #include <fmt/format.h>
+
+  fmt::print(fmt::color::steel_blue, "Some beautiful text");
+  ```
+
+  The old API (the `print_colored` and `vprint_colored` functions and
+  the `color` enum) is now deprecated.
+  (https://github.com/fmtlib/fmt/issues/762
+  https://github.com/fmtlib/fmt/pull/767). thanks @Remotion.
+
+- Added quotes to strings in ranges and tuples
+  (https://github.com/fmtlib/fmt/pull/766). Thanks @Remotion.
+
+- Made `format_to` work with `basic_memory_buffer`
+  (https://github.com/fmtlib/fmt/issues/776).
+
+- Added `vformat_to_n` and `wchar_t` overload of `format_to_n`
+  (https://github.com/fmtlib/fmt/issues/764,
+  https://github.com/fmtlib/fmt/issues/769).
+
+- Made `is_range` and `is_tuple_like` part of public (experimental)
+  API to allow specialization for user-defined types
+  (https://github.com/fmtlib/fmt/issues/751,
+  https://github.com/fmtlib/fmt/pull/759). Thanks @drrlvn.
+
+- Added more compilers to continuous integration and increased
+  `FMT_PEDANTIC` warning levels
+  (https://github.com/fmtlib/fmt/pull/736). Thanks @eliaskosunen.
+
+- Fixed compilation with MSVC 2013.
+
+- Fixed handling of user-defined types in `format_to`
+  (https://github.com/fmtlib/fmt/issues/793).
+
+- Forced linking of inline `vformat` functions into the library
+  (https://github.com/fmtlib/fmt/issues/795).
+
+- Fixed incorrect call to on_align in `'{:}='`
+  (https://github.com/fmtlib/fmt/issues/750).
+
+- Fixed floating-point formatting to a non-back_insert_iterator with
+  sign & numeric alignment specified
+  (https://github.com/fmtlib/fmt/issues/756).
+
+- Fixed formatting to an array with `format_to_n`
+  (https://github.com/fmtlib/fmt/issues/778).
+
+- Fixed formatting of more than 15 named arguments
+  (https://github.com/fmtlib/fmt/issues/754).
+
+- Fixed handling of compile-time strings when including
+  `fmt/ostream.h`. (https://github.com/fmtlib/fmt/issues/768).
+
+- Fixed various compiler warnings and errors
+  (https://github.com/fmtlib/fmt/issues/742,
+  https://github.com/fmtlib/fmt/issues/748,
+  https://github.com/fmtlib/fmt/issues/752,

+  https://github.com/fmtlib/fmt/pull/792,
+  https://github.com/fmtlib/fmt/pull/800).
+  Thanks @Remotion, @gabime, @foonathan, @Dark-Passenger and @0x8000-0000.
+
+# 5.0.0 - 2018-05-21
+
+- Added a requirement for partial C++11 support, most importantly
+  variadic templates and type traits, and dropped `FMT_VARIADIC_*`
+  emulation macros. Variadic templates are available since GCC 4.4,
+  Clang 2.9 and MSVC 18.0 (2013). For older compilers use {fmt}
+  [version 4.x](https://github.com/fmtlib/fmt/releases/tag/4.1.0)
+  which continues to be maintained and works with C++98 compilers.
+
+- Renamed symbols to follow standard C++ naming conventions and
+  proposed a subset of the library for standardization in [P0645R2
+  Text Formatting](https://wg21.link/P0645).
+
+- Implemented `constexpr` parsing of format strings and [compile-time
+  format string
+  checks](https://fmt.dev/latest/api.html#compile-time-format-string-checks).
+  For example
+
+  ```c++
+  #include <fmt/format.h>
+
+  std::string s = format(fmt("{:d}"), "foo");
+  ```
+
+  gives a compile-time error because `d` is an invalid specifier for
+  strings ([godbolt](https://godbolt.org/g/rnCy9Q)):
+
+      ...
+      <source>:4:19: note: in instantiation of function template specialization 'fmt::v5::format<S, char [4]>' requested here
+        std::string s = format(fmt("{:d}"), "foo");
+                        ^
+      format.h:1337:13: note: non-constexpr function 'on_error' cannot be used in a constant expression
+          handler.on_error("invalid type specifier");
+
+  Compile-time checks require relaxed `constexpr` (C++14 feature)
+  support. If the latter is not available, checks will be performed at
+  runtime.
+
+- Separated format string parsing and formatting in the extension API
+  to enable compile-time format string processing. For example
+
+  ```c++
+  struct Answer {};
+
+  namespace fmt {
+  template <>
+  struct formatter<Answer> {
+    constexpr auto parse(parse_context& ctx) {
+      auto it = ctx.begin();
+      spec = *it;
+      if (spec != 'd' && spec != 's')
+        throw format_error("invalid specifier");
+      return ++it;
+    }
+
+    template <typename FormatContext>
+    auto format(Answer, FormatContext& ctx) {
+      return spec == 's' ?
+        format_to(ctx.begin(), "{}", "fourty-two") :
+        format_to(ctx.begin(), "{}", 42);
+    }
+
+    char spec = 0;
+  };
+  }
+
+  std::string s = format(fmt("{:x}"), Answer());
+  ```
+
+  gives a compile-time error due to invalid format specifier
+  ([godbolt](https://godbolt.org/g/2jQ1Dv)):
+
+      ...
+      <source>:12:45: error: expression '<throw-expression>' is not a constant expression
+             throw format_error("invalid specifier");
+
+- Added [iterator
+  support](https://fmt.dev/latest/api.html#output-iterator-support):
+
+  ```c++
+  #include <vector>
+  #include <fmt/format.h>
+
+  std::vector<char> out;
+  fmt::format_to(std::back_inserter(out), "{}", 42);
+  ```
+
+- Added the
+  [format_to_n](https://fmt.dev/latest/api.html#_CPPv2N3fmt11format_to_nE8OutputItNSt6size_tE11string_viewDpRK4Args)
+  function that restricts the output to the specified number of
+  characters (https://github.com/fmtlib/fmt/issues/298):
+
+  ```c++
+  char out[4];
+  fmt::format_to_n(out, sizeof(out), "{}", 12345);
+  // out == "1234" (without terminating '\0')
+  ```
+
+- Added the [formatted_size](
+  https://fmt.dev/latest/api.html#_CPPv2N3fmt14formatted_sizeE11string_viewDpRK4Args)
+  function for computing the output size:
+
+  ```c++
+  #include <fmt/format.h>
+
+  auto size = fmt::formatted_size("{}", 12345); // size == 5
+  ```
+
+- Improved compile times by reducing dependencies on standard headers
+  and providing a lightweight [core
+  API](https://fmt.dev/latest/api.html#core-api):
+
+  ```c++
+  #include <fmt/core.h>
+
+  fmt::print("The answer is {}.", 42);
+  ```
+
+  See [Compile time and code
+  bloat](https://github.com/fmtlib/fmt#compile-time-and-code-bloat).
+
+- Added the [make_format_args](
+  https://fmt.dev/latest/api.html#_CPPv2N3fmt16make_format_argsEDpRK4Args)
+  function for capturing formatting arguments:
+
+  ```c++
+  // Prints formatted error message.
+  void vreport_error(const char *format, fmt::format_args args) {
+    fmt::print("Error: ");
+    fmt::vprint(format, args);
+  }
+  template <typename... Args>
+  void report_error(const char *format, const Args & ... args) {
+    vreport_error(format, fmt::make_format_args(args...));
+  }
+  ```
+
+- Added the `make_printf_args` function for capturing `printf`
+  arguments (https://github.com/fmtlib/fmt/issues/687,
+  https://github.com/fmtlib/fmt/pull/694). Thanks @Kronuz.
+
+- Added prefix `v` to non-variadic functions taking `format_args` to
+  distinguish them from variadic ones:
+
+  ```c++
+  std::string vformat(string_view format_str, format_args args);
+
+  template <typename... Args>
+  std::string format(string_view format_str, const Args & ... args);
+  ```
+
+- Added experimental support for formatting ranges, containers and
+  tuple-like types in `fmt/ranges.h`
+  (https://github.com/fmtlib/fmt/pull/735):
+
+  ```c++
+  #include <fmt/ranges.h>
+
+  std::vector<int> v = {1, 2, 3};
+  fmt::print("{}", v); // prints {1, 2, 3}
+  ```
+
+  Thanks @Remotion.
+
+- Implemented `wchar_t` date and time formatting
+  (https://github.com/fmtlib/fmt/pull/712):
+
+  ```c++
+  #include <fmt/time.h>
+
+  std::time_t t = std::time(nullptr);
+  auto s = fmt::format(L"The date is {:%Y-%m-%d}.", *std::localtime(&t));
+  ```
+
+  Thanks @DanielaE.
+
+- Provided more wide string overloads
+  (https://github.com/fmtlib/fmt/pull/724). Thanks @DanielaE.
+
+- Switched from a custom null-terminated string view class to
+  `string_view` in the format API and provided `fmt::string_view`
+  which implements a subset of `std::string_view` API for pre-C++17
+  systems.
+
+- Added support for `std::experimental::string_view`
+  (https://github.com/fmtlib/fmt/pull/607):
+
+  ```c++
+  #include <fmt/core.h>
+  #include <experimental/string_view>
+
+  fmt::print("{}", std::experimental::string_view("foo"));
+  ```
+
+  Thanks @virgiliofornazin.
+
+- Allowed mixing named and automatic arguments:
+
+  ```c++
+  fmt::format("{} {two}", 1, fmt::arg("two", 2));
+  ```
+
+- Removed the write API in favor of the [format
+  API](https://fmt.dev/latest/api.html#format-api) with compile-time
+  handling of format strings.
+
+- Disallowed formatting of multibyte strings into a wide character
+  target (https://github.com/fmtlib/fmt/pull/606).
+
+- Improved documentation
+  (https://github.com/fmtlib/fmt/pull/515,

+
+# 3.0.0 - 2016-05-07
+
+- The project has been renamed from C++ Format (cppformat) to fmt for
+  consistency with the used namespace and macro prefix
+  (https://github.com/fmtlib/fmt/issues/307). Library headers
+  are now located in the `fmt` directory:
+
+  ```c++
+  #include "fmt/format.h"
+  ```
+
+  Including `format.h` from the `cppformat` directory is deprecated
+  but works via a proxy header which will be removed in the next major
+  version.
+
+  The documentation is now available at <https://fmt.dev>.
+
+- Added support for
+  [strftime](http://en.cppreference.com/w/cpp/chrono/c/strftime)-like
+  [date and time
+  formatting](https://fmt.dev/3.0.0/api.html#date-and-time-formatting)
+  (https://github.com/fmtlib/fmt/issues/283):
+
+  ```c++
+  #include "fmt/time.h"
+
+  std::time_t t = std::time(nullptr);
+  // Prints "The date is 2016-04-29." (with the current date)
+  fmt::print("The date is {:%Y-%m-%d}.", *std::localtime(&t));
+  ```
+
+- `std::ostream` support including formatting of user-defined types
+  that provide overloaded `operator<<` has been moved to
+  `fmt/ostream.h`:
+
+  ```c++
+  #include "fmt/ostream.h"
+
+  class Date {
+    int year_, month_, day_;
+  public:
+    Date(int year, int month, int day) : year_(year), month_(month), day_(day) {}
+
+    friend std::ostream &operator<<(std::ostream &os, const Date &d) {
+      return os << d.year_ << '-' << d.month_ << '-' << d.day_;
+    }
+  };
+
+  std::string s = fmt::format("The date is {}", Date(2012, 12, 9));
+  // s == "The date is 2012-12-9"
+  ```
+
+- Added support for [custom argument
+  formatters](https://fmt.dev/3.0.0/api.html#argument-formatters)
+  (https://github.com/fmtlib/fmt/issues/235).
+
+- Added support for locale-specific integer formatting with the `n`
+  specifier (https://github.com/fmtlib/fmt/issues/305):
+
+  ```c++
+  std::setlocale(LC_ALL, "en_US.utf8");
+  fmt::print("cppformat: {:n}\n", 1234567); // prints 1,234,567
+  ```
+
+- Sign is now preserved when formatting an integer with an incorrect
+  `printf` format specifier
+  (https://github.com/fmtlib/fmt/issues/265):
+
+  ```c++
+  fmt::printf("%lld", -42); // prints -42
+  ```
+
+  Note that it would be an undefined behavior in `std::printf`.
+
+- Length modifiers such as `ll` are now optional in printf formatting
+  functions and the correct type is determined automatically
+  (https://github.com/fmtlib/fmt/issues/255):
+
+  ```c++
+  fmt::printf("%d", std::numeric_limits<long long>::max());
+  ```
+
+  Note that it would be an undefined behavior in `std::printf`.
+
+- Added initial support for custom formatters
+  (https://github.com/fmtlib/fmt/issues/231).
+
+- Fixed detection of user-defined literal support on Intel C++
+  compiler (https://github.com/fmtlib/fmt/issues/311,
+  https://github.com/fmtlib/fmt/pull/312).
+  Thanks @dean0x7d and @speth.

+      Format is included as a CMake subproject. They can be enabled by
+      setting `FMT_DOC`, `FMT_INSTALL`, and `FMT_TEST` in the parent
+      project.
+
+  Thanks @niosHD.

+
+# 2.0.0 - 2015-12-01
+
+## General
+
+- \[Breaking\] Named arguments
+  (https://github.com/fmtlib/fmt/pull/169,
+  https://github.com/fmtlib/fmt/pull/173,
+  https://github.com/fmtlib/fmt/pull/174):
+
+  ```c++
+  fmt::print("The answer is {answer}.", fmt::arg("answer", 42));
+  ```
+
+  Thanks @jamboree.
+
+- \[Experimental\] User-defined literals for format and named
+  arguments (https://github.com/fmtlib/fmt/pull/204,
+  https://github.com/fmtlib/fmt/pull/206,
+  https://github.com/fmtlib/fmt/pull/207):
+
+  ```c++
+  using namespace fmt::literals;
+  fmt::print("The answer is {answer}.", "answer"_a=42);
+  ```
+
+  Thanks @dean0x7d.
+
+- \[Breaking\] Formatting of more than 16 arguments is now supported
+  when using variadic templates
+  (https://github.com/fmtlib/fmt/issues/141). Thanks @Shauren.
+
+- Runtime width specification
+  (https://github.com/fmtlib/fmt/pull/168):
+
+  ```c++
+  fmt::format("{0:{1}}", 42, 5); // gives "   42"
+  ```
+
+  Thanks @jamboree.
+
+- \[Breaking\] Enums are now formatted with an overloaded
+  `std::ostream` insertion operator (`operator<<`) if available
+  (https://github.com/fmtlib/fmt/issues/232).
+
+- \[Breaking\] Changed default `bool` format to textual, \"true\" or
+  \"false\" (https://github.com/fmtlib/fmt/issues/170):
+
+  ```c++
+  fmt::print("{}", true); // prints "true"
+  ```
+
+  To print `bool` as a number use numeric format specifier such as
+  `d`:
+
+  ```c++
+  fmt::print("{:d}", true); // prints "1"
+  ```
+
+- `fmt::printf` and `fmt::sprintf` now support formatting of `bool`
+  with the `%s` specifier giving textual output, \"true\" or \"false\"
+  (https://github.com/fmtlib/fmt/pull/223):
+
+  ```c++
+  fmt::printf("%s", true); // prints "true"
+  ```
+
+  Thanks @LarsGullik.
+
+- \[Breaking\] `signed char` and `unsigned char` are now formatted as
+  integers by default
+  (https://github.com/fmtlib/fmt/pull/217).
+
+- \[Breaking\] Pointers to C strings can now be formatted with the `p`
+  specifier (https://github.com/fmtlib/fmt/pull/223):
+
+  ```c++
+  fmt::print("{:p}", "test"); // prints pointer value
+  ```
+
+  Thanks @LarsGullik.
+
+- \[Breaking\] `fmt::printf` and `fmt::sprintf` now print null
+  pointers as `(nil)` and null strings as `(null)` for consistency
+  with glibc (https://github.com/fmtlib/fmt/pull/226).
+  Thanks @LarsGullik.
+
+- \[Breaking\] `fmt::(s)printf` now supports formatting of objects of
+  user-defined types that provide an overloaded `std::ostream`
+  insertion operator (`operator<<`)
+  (https://github.com/fmtlib/fmt/issues/201):
+
+  ```c++
+  fmt::printf("The date is %s", Date(2012, 12, 9));
+  ```
+
+- \[Breaking\] The `Buffer` template is now part of the public API and
+  can be used to implement custom memory buffers
+  (https://github.com/fmtlib/fmt/issues/140). Thanks @polyvertex.
+
+- \[Breaking\] Improved compatibility between `BasicStringRef` and
+  [std::experimental::basic_string_view](
+  http://en.cppreference.com/w/cpp/experimental/basic_string_view)
+  (https://github.com/fmtlib/fmt/issues/100,
+  https://github.com/fmtlib/fmt/issues/159,
+  https://github.com/fmtlib/fmt/issues/183):
+
+  -   Comparison operators now compare string content, not pointers
+  -   `BasicStringRef::c_str` replaced by `BasicStringRef::data`
+  -   `BasicStringRef` is no longer assumed to be null-terminated
+
+  References to null-terminated strings are now represented by a new
+  class, `BasicCStringRef`.
+
+- Dependency on pthreads introduced by Google Test is now optional
+  (https://github.com/fmtlib/fmt/issues/185).
+
+- New CMake options `FMT_DOC`, `FMT_INSTALL` and `FMT_TEST` to control
+  generation of `doc`, `install` and `test` targets respectively, on
+  by default (https://github.com/fmtlib/fmt/issues/197,
+  https://github.com/fmtlib/fmt/issues/198,
+  https://github.com/fmtlib/fmt/issues/200). Thanks @maddinat0r.
+
+- `noexcept` is now used when compiling with MSVC2015
+  (https://github.com/fmtlib/fmt/pull/215). Thanks @dmkrepo.
+
+- Added an option to disable use of `windows.h` when
+  `FMT_USE_WINDOWS_H` is defined as 0 before including `format.h`
+  (https://github.com/fmtlib/fmt/issues/171). Thanks @alfps.
+
+- \[Breaking\] `windows.h` is now included with `NOMINMAX` unless
+  `FMT_WIN_MINMAX` is defined. This is done to prevent breaking code
+  using `std::min` and `std::max` and only affects the header-only
+  configuration (https://github.com/fmtlib/fmt/issues/152,
+  https://github.com/fmtlib/fmt/pull/153,
+  https://github.com/fmtlib/fmt/pull/154). Thanks @DevO2012.
+
+- Improved support for custom character types
+  (https://github.com/fmtlib/fmt/issues/171). Thanks @alfps.
+
+- Added an option to disable use of IOStreams when `FMT_USE_IOSTREAMS`
+  is defined as 0 before including `format.h`
+  (https://github.com/fmtlib/fmt/issues/205,
+  https://github.com/fmtlib/fmt/pull/208). Thanks @JodiTheTigger.
+
+- Improved detection of `isnan`, `isinf` and `signbit`.
+
+## Optimization
+
+- Made formatting of user-defined types more efficient with a custom
+  stream buffer (https://github.com/fmtlib/fmt/issues/92,
+  https://github.com/fmtlib/fmt/pull/230). Thanks @NotImplemented.
+- Further improved performance of `fmt::Writer` on integer formatting
+  and fixed a minor regression. Now it is \~7% faster than
+  `karma::generate` on Karma\'s benchmark
+  (https://github.com/fmtlib/fmt/issues/186).
+- \[Breaking\] Reduced [compiled code
+  size](https://github.com/fmtlib/fmt#compile-time-and-code-bloat)
+  (https://github.com/fmtlib/fmt/issues/143,
+  https://github.com/fmtlib/fmt/pull/149).
+
+## Distribution
+
+- \[Breaking\] Headers are now installed in
+  `${CMAKE_INSTALL_PREFIX}/include/cppformat`
+  (https://github.com/fmtlib/fmt/issues/178). Thanks @jackyf.
+
+- \[Breaking\] Changed the library name from `format` to `cppformat`

+  https://github.com/fmtlib/fmt/pull/116,
+  https://github.com/fmtlib/fmt/pull/118 and

+  (https://github.com/fmtlib/fmt/pull/107). Thanks @newnon.
+
+  The [android-ndk-example](https://github.com/fmtlib/android-ndk-example)
+  repository provides and example of using C++ Format with Android NDK:
+
+  ![](https://raw.githubusercontent.com/fmtlib/android-ndk-example/master/screenshot.png)
+
+- Improved documentation of `SystemError` and `WindowsError`

+  https://github.com/fmtlib/fmt/pull/111
+  https://github.com/fmtlib/fmt/pull/112). Thanks @CarterLi.
+
+- Improved compile-time errors when formatting wide into narrow
+  strings (https://github.com/fmtlib/fmt/issues/117).

+
+- Fixed header-only build on OS X with GCC 4.9
+  (https://github.com/fmtlib/fmt/issues/124).
+
+- Fixed packaging issues (https://github.com/fmtlib/fmt/issues/94).
+
+- Added [changelog](https://github.com/fmtlib/fmt/blob/master/ChangeLog.md)
+  (https://github.com/fmtlib/fmt/issues/103).
+
+# 1.0.0 - 2015-02-05
+
+- Add support for a header-only configuration when `FMT_HEADER_ONLY`
+  is defined before including `format.h`:
+
+  ```c++
+  #define FMT_HEADER_ONLY
+  #include "format.h"
+  ```
+
+- Compute string length in the constructor of `BasicStringRef` instead
+  of the `size` method
+  (https://github.com/fmtlib/fmt/issues/79). This eliminates
+  size computation for string literals on reasonable optimizing
+  compilers.
+
+- Fix formatting of types with overloaded `operator <<` for
+  `std::wostream` (https://github.com/fmtlib/fmt/issues/86):
+
+  ```c++
+  fmt::format(L"The date is {0}", Date(2012, 12, 9));
+  ```
+
+- Fix linkage of tests on Arch Linux
+  (https://github.com/fmtlib/fmt/issues/89).
+
+- Allow precision specifier for non-float arguments
+  (https://github.com/fmtlib/fmt/issues/90):
+
+  ```c++
+  fmt::print("{:.3}\n", "Carpet"); // prints "Car"
+  ```
+
+- Fix build on Android NDK (https://github.com/fmtlib/fmt/issues/93).
+
+- Improvements to documentation build procedure.
+
+- Remove `FMT_SHARED` CMake variable in favor of standard [BUILD_SHARED_LIBS](
+  http://www.cmake.org/cmake/help/v3.0/variable/BUILD_SHARED_LIBS.html).
+
+- Fix error handling in `fmt::fprintf`.
+
+- Fix a number of warnings.
+
+# 0.12.0 - 2014-10-25
+
+- \[Breaking\] Improved separation between formatting and buffer
+  management. `Writer` is now a base class that cannot be instantiated
+  directly. The new `MemoryWriter` class implements the default buffer
+  management with small allocations done on stack. So `fmt::Writer`
+  should be replaced with `fmt::MemoryWriter` in variable
+  declarations.
+
+  Old code:
+
+  ```c++
+  fmt::Writer w;
+  ```
+
+  New code:
+
+  ```c++
+  fmt::MemoryWriter w;
+  ```
+
+  If you pass `fmt::Writer` by reference, you can continue to do so:
+
+  ```c++
+  void f(fmt::Writer &w);
+  ```
+
+  This doesn\'t affect the formatting API.
+
+- Support for custom memory allocators
+  (https://github.com/fmtlib/fmt/issues/69)
+
+- Formatting functions now accept [signed char]{.title-ref} and
+  [unsigned char]{.title-ref} strings as arguments
+  (https://github.com/fmtlib/fmt/issues/73):
+
+  ```c++
+  auto s = format("GLSL version: {}", glGetString(GL_VERSION));
+  ```
+
+- Reduced code bloat. According to the new [benchmark
+  results](https://github.com/fmtlib/fmt#compile-time-and-code-bloat),
+  cppformat is close to `printf` and by the order of magnitude better
+  than Boost Format in terms of compiled code size.
+
+- Improved appearance of the documentation on mobile by using the
+  [Sphinx Bootstrap
+  theme](http://ryan-roemer.github.io/sphinx-bootstrap-theme/):
+
+  | Old | New |
+  | --- | --- |
+  | ![](https://cloud.githubusercontent.com/assets/576385/4792130/cd256436-5de3-11e4-9a62-c077d0c2b003.png) | ![](https://cloud.githubusercontent.com/assets/576385/4792131/cd29896c-5de3-11e4-8f59-cac952942bf0.png) |
+
+# 0.11.0 - 2014-08-21
+
+- Safe printf implementation with a POSIX extension for positional
+  arguments:
+
+  ```c++
+  fmt::printf("Elapsed time: %.2f seconds", 1.23);
+  fmt::printf("%1$s, %3$d %2$s", weekday, month, day);
+  ```
+
+- Arguments of `char` type can now be formatted as integers (Issue
+  https://github.com/fmtlib/fmt/issues/55):
+
+  ```c++
+  fmt::format("0x{0:02X}", 'a');
+  ```
+
+- Deprecated parts of the API removed.
+
+- The library is now built and tested on MinGW with Appveyor in
+  addition to existing test platforms Linux/GCC, OS X/Clang,
+  Windows/MSVC.
+
+# 0.10.0 - 2014-07-01
+
+**Improved API**
+
+- All formatting methods are now implemented as variadic functions
+  instead of using `operator<<` for feeding arbitrary arguments into a
+  temporary formatter object. This works both with C++11 where
+  variadic templates are used and with older standards where variadic
+  functions are emulated by providing lightweight wrapper functions
+  defined with the `FMT_VARIADIC` macro. You can use this macro for
+  defining your own portable variadic functions:
+
+  ```c++
+  void report_error(const char *format, const fmt::ArgList &args) {
+    fmt::print("Error: {}");
+    fmt::print(format, args);
+  }
+  FMT_VARIADIC(void, report_error, const char *)
+
+  report_error("file not found: {}", path);
+  ```
+
+  Apart from a more natural syntax, this also improves performance as
+  there is no need to construct temporary formatter objects and
+  control arguments\' lifetimes. Because the wrapper functions are
+  very lightweight, this doesn\'t cause code bloat even in pre-C++11
+  mode.
+
+- Simplified common case of formatting an `std::string`. Now it
+  requires a single function call:
+
+  ```c++
+  std::string s = format("The answer is {}.", 42);
+  ```
+
+  Previously it required 2 function calls:
+
+  ```c++
+  std::string s = str(Format("The answer is {}.") << 42);
+  ```
+
+  Instead of unsafe `c_str` function, `fmt::Writer` should be used
+  directly to bypass creation of `std::string`:
+
+  ```c++
+  fmt::Writer w;
+  w.write("The answer is {}.", 42);
+  w.c_str();  // returns a C string
+  ```
+
+  This doesn\'t do dynamic memory allocation for small strings and is
+  less error prone as the lifetime of the string is the same as for
+  `std::string::c_str` which is well understood (hopefully).
+
+- Improved consistency in naming functions that are a part of the
+  public API. Now all public functions are lowercase following the
+  standard library conventions. Previously it was a combination of
+  lowercase and CapitalizedWords. Issue
+  https://github.com/fmtlib/fmt/issues/50.
+
+- Old functions are marked as deprecated and will be removed in the
+  next release.
+
+**Other Changes**
+
+- Experimental support for printf format specifications (work in
+  progress):
+
+  ```c++
+  fmt::printf("The answer is %d.", 42);
+  std::string s = fmt::sprintf("Look, a %s!", "string");
+  ```
+
+- Support for hexadecimal floating point format specifiers `a` and
+  `A`:
+
+  ```c++
+  print("{:a}", -42.0); // Prints -0x1.5p+5
+  print("{:A}", -42.0); // Prints -0X1.5P+5
+  ```
+
+- CMake option `FMT_SHARED` that specifies whether to build format as
+  a shared library (off by default).
+
+# 0.9.0 - 2014-05-13
+
+- More efficient implementation of variadic formatting functions.
+
+- `Writer::Format` now has a variadic overload:
+
+  ```c++
+  Writer out;
+  out.Format("Look, I'm {}!", "variadic");
+  ```
+
+- For efficiency and consistency with other overloads, variadic
+  overload of the `Format` function now returns `Writer` instead of
+  `std::string`. Use the `str` function to convert it to
+  `std::string`:
+
+  ```c++
+  std::string s = str(Format("Look, I'm {}!", "variadic"));
+  ```
+
+- Replaced formatter actions with output sinks: `NoAction` -\>
+  `NullSink`, `Write` -\> `FileSink`, `ColorWriter` -\>
+  `ANSITerminalSink`. This improves naming consistency and shouldn\'t
+  affect client code unless these classes are used directly which
+  should be rarely needed.
+
+- Added `ThrowSystemError` function that formats a message and throws
+  `SystemError` containing the formatted message and system-specific
+  error description. For example, the following code
+
+  ```c++
+  FILE *f = fopen(filename, "r");
+  if (!f)
+    ThrowSystemError(errno, "Failed to open file '{}'") << filename;
+  ```
+
+  will throw `SystemError` exception with description \"Failed to open
+  file \'\<filename\>\': No such file or directory\" if file doesn\'t
+  exist.
+
+- Support for AppVeyor continuous integration platform.
+
+- `Format` now throws `SystemError` in case of I/O errors.
+
+- Improve test infrastructure. Print functions are now tested by
+  redirecting the output to a pipe.
