 8.0.0 - TBD
 -----------
 
+* Added compile-time formatting
+  (`#2019 <https://github.com/fmtlib/fmt/pull/2019>`_,
+  `#2044 <https://github.com/fmtlib/fmt/pull/2044>`_). For example:
+
+  .. code:: c++
+
+     #include <fmt/compile.h>
+
+     consteval std::array<char, 10> compile_time_itoa(int) {
+       using namespace fmt::literals;
+       auto result = std::array<char, 10>();
+       fmt::format_to(result.data(), "{}"_cf, 42);
+       return result;
+     }
+
+  Most of formatting functionality is available at compile time with a notable
+  exception of floating-point numbers and pointers.
+  Thanks `@alexezeder (Alexey Ochapov) <https://github.com/alexezeder>`_.
+
 * Optimized handling of format specifiers during format string
   compilation, including but not limited to hexadecimal formatting
   (`#1944 <https://github.com/fmtlib/fmt/issues/1944>`_).
 
+* Made ``std::byte`` formattable with ``fmt::join``
+  (`#1981 <https://github.com/fmtlib/fmt/issues/1981>`_). For example:
+
+  .. code:: c++
+
+     #include <fmt/format.h>
+     #include <cstddef>
+     #include <vector>
+
+     int main() {
+       auto bytes = std::vector{std::byte(4), std::byte(2)};
+       fmt::print("{}", fmt::join(bytes, ""));
+     }
+
+  prints "42".
+
 * Formatting floating-point numbers no longer produces trailing zeros by
   default for consistency with Python and ``std::format``. For example:

 * The experimental fast output stream (``fmt::ostream``) is now truncated by
   default for consistency with ``fopen``. For example:

   writes "Ford" to the file "guide". To preserve the old file content if any
   pass ``fmt::file::WRONLY | fmt::file::CREATE`` flags to ``fmt::output_file``.
