+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.
+
+Some of the changes listed in this file include issue tracking numbers
+corresponding to tasks in the Qt Bug Tracker:

+
+ - [oss-fuzz-24347] QXmlStreamReader: No longer resizes readBuffer to a size
+ it already has. When resizing it to 0 it will cause it to allocate memory.
+ This will then cause append() to copy the data from the other string instead
+ of using copy on write.
+ - [oss-fuzz-24702] QTextHtmlParserNode: Fixed an integer-overflow in variantHash() due
+ to extreme values for the font's pixelsize.
+ - [QTBUG-86702] Gif decoder: fixed a read error caused by a ub check
+ The recently added check to avoid negative-bitshift ub ignored that
+ the algorithm will sometimes use a negative bitcount value as a flag.
+ This caused a reading failure for some frames.
+ - [QTBUG-86547] Fixed a double deletion in QDomAttr::setNodeValue()
+ - [QTBUG-86691] xpm handler: fixed read error caused by off-by-one in overflow check
+ The recently introduced overflow check for 8 bit images was too
+ aggressive, causing the last pixel on each line to be rejected. This is also
+ fixed for 32bit images.
+ - [oss-fuzz-22997] Avoided a potential ub in a corrupt bmp file
+ - [QTBUG-85725] Cocoa: Translated the buttons used for the native font and
+ color dialogs
+ - [QTBUG-86019] Fixed crash when serializing default-constructed QTimeZone
+ - [oss-fuzz-24273] QBezier: No longer calculates a unit vector when length is null to
+ prevent a divide by zero.
+ - [QTBUG-81723] xcb: Fixed flushing of native subwindows when not using shared memory
+ When using X-forwarding shared memory is not used for the backing
+ store image, and ended up in a code path where we first copied the updated
+ parts of the backing store from our client side image over to the
+ server, and then flush those parts from the server-side image to the
+ window.
+ - [QTBUG-85764] Fixed starting of iOS applications on Big Sur
+ - [QTBUG-85580] QByteArray::toDouble: fixed buffer overflow reads on fromRawData()
+ - [QTBUG-85193] Allowed smooth curve stroking for very wide lines to ensure they
+ are rendered better.
+ - [QTBUG-85915] macOS: Fixed crash when re-using the backing store for a
+ re-created QWindow. This was triggered when reopening a QComboBox after
+ switching from one screen to another.
+ - [oss-fuzz-23220] Sanitized the lengthValue in CSS parser by limiting the
+ LengthData to the integer range before rounding it, taking into account
+ that qRound() substracts 1 from negative values.
+ - [oss-fuzz-21860] Checked return values of hex2int in get_hex_rgb
+ - [oss-fuzz-23988] Fixed buffer overflow
+ - [oss-fuzz-23735] Multiplied instead of shifting for negative values
+ - [QTBUG-85528] Disabled PCRE2 JIT on macOS ARM64
+ - [QTBUG-85279] macOS: Excluded 32-bit builds by checking pointer size
+ - [QTBUG-85279] Fixed compilation of Qt on Apple Silicon (arm64)
+ - [QTBUG-76924] Prevented the setting of focus on a proxy widget that does
+ not take focus
+ - [QTBUG-71548] Worked around a regression in the MSVC 2019 6.6 STL triggered
+ when building qttranslations.
+ - [QTBUG-84383] Fixed UITouch event handling on tvOS to prevent a crash
+ when touchesEnd: could be called with touches that were not included in
+ touchesBegain:.
+ - [QTBUG-84762] macOS: Ensured QCocoaGLContext cleans up more often to
+ release unneeded NSViews
+ - [QTBUG-77320] Android: Accessibility is now activated when appropriate
+ - [QTCREATORBUG-24195] Now always shows a submenu on its parent menu's screen
+
