+Qt 5.12.5 is a bug-fix release. It maintains both forward and backward
+compatibility (source and binary) with Qt 5.12.0 through 5.12.4.

+For more details, refer to the online documentation included in this
+distribution. The documentation is also available online:

+
+The Qt version 5.12 series is binary compatible with the 5.11.x series.
+Applications compiled for 5.11 will continue to run with 5.12.

+
+ - QBitArray:
+   * Fixed two bugs that caused QBitArrays created using fromBits() not to
+     compare equal to the equivalent QBitArray created using other methods
+     if the size was zero or not a multiple of 4. If the size modulus 8 was
+     5, 6, or 7, the data was actually incorrect.
+
+ - QCborStreamReader:
+   * Fixed a bug that caused the QIODevice that the data was being read
+     from not to show the entire CBOR message as consumed. This allows the
+     user to consume data that may follow the CBOR payload.
+
+ - QCryptographicHash:
+   * Fixed a bug that caused the SHA-3 and Keccak algorithms to crash if
+     passed 256 MB of data or more.
+
+ - QObject:
+   * Fixed a resource leak caused by a race condition if multiple QObjects
+     were created at the same time, for the first time in an application,
+     from multiple threads (implies threads not started with QThread).
+
+ - QStorageInfo:
+   * Fixed a bug that caused QStorageInfo to be unable to report all
+     filesystems if the options to mounted filesystems were too long (over
+     900 characters, roughly), such as those found in Docker overlay
+     mounts.
+
+ - QTimeZone:
+   * The IANA timezone database backend now properly follows symlinks even
+     when they point to variable locations like /run or /var (useful when
+     /etc is mounted read-only).

+     larger than it was supposed to.
+   * [QTBUG-55096][QTBUG-74761] Fixed bug where regular text rendered with
+     a color font would always display in black.

+****************************************************************************
+
+ - [QTBUG-76521] RCC's default compression algorithm was changed back to
+   Zlib, as it was in all previous releases until 5.13.0. The default will
+   remain Zlib for all Qt 5.x releases but will change in Qt 6.0. To
+   activate Zstd compression for your resources, either pass the
+   --compress-algo=zstd option to the rcc tool or add the XML attribute
+   compression-algorithm="zstd" to the <file> tags in the .qrc file.

+
+ - Global:
+   * [QTBUG-72073] Added the QT_NO_FLOAT16_OPERATORS macro in order to work
+     around a Microsoft <= VS2017 compiler bug that is exposed when using
+     std::bitset along with any Qt header that includes <qfloat16.h>.

+   * Fixed a bug that caused the QIODevice that the data was being read
+     from not to show the entire CBOR message as consumed. This allows the

+     mounts.
+
+ - QTextBoundaryFinder:
+   * Sentence breaking now no longer breaks between uppercase letters and
+     comma. This is a deviation from the Unicode specification, but
+     produces less surprising behavior.
+
+ - QTimeZone:
+   * The IANA timezone database backend now properly follows symlinks even
+     when they point to variable locations like /run or /var (useful when
