Release note  
============  
  
Qt 6.2.4 release is a patch release made on the top of Qt 6.2.3.  
As a patch release, Qt 6.2.4 does not add any new functionality but provides  
bug fixes and other improvements and maintains both forward and backward  
compatibility (source and binary) with Qt 6.2.3.  

For detailed information about Qt 6.2, refer to the online documentation  
included in this distribution. The documentation is also available online:  
  
https://doc.qt.io/qt-6/index.html  
  
The Qt version 6.2 series is binary compatible with the 6.1.x series.  
Applications compiled for 6.1 will continue to run with 6.2.  
  
Some of the changes listed in this file include issue tracking numbers  
corresponding to tasks in the Qt Bug Tracker:  
  
https://bugreports.qt.io/  
  
Each of these identifiers can be entered in the bug tracker to obtain  
more information about a particular change.  
  
To make it easier to port to Qt 6, we have created a porting guide to  
summarize those changes and provide guidance to handle them. In the  
guide, you can find links to articles about changes that may affect your  
application and help you transition from Qt 5.15 to Qt 6:

Important Changes  
-----------------  
  
### qtbase  
* fa8b14f830 QTzTimeZonePrivate: fix UB (data race on m_icu)  
Fixed a data race on Unix platforms when implicitly-shared copies of  
QTimeZone objects were used in certain ways (e.g. calling displayName())  
from different threads and Qt was configured with ICU support.  
  
* 6eed0d3f4e JSON: When clearing duplicate object entries, also clear  
containers  
A memory leak in the JSON parser when reading objects with duplicate  
keys was fixed.  
  
* 9540c0b27f Fix crash when text shaping fails  
Fixed a possible crash with certain fonts when shaping strings  
consisting only of control characters.  
  
* 3c193fa077 QScreen_win: retrieve user friendly monitor name  
QScreen::name() now returns the user friendly name instead of the GDI  
device name on Windows. This is consistent with other platforms and also  
obeys the documentation.  
  
* 8f79520cd6 Enable all supported 1.0 device features in QVulkanWindow  
QVulkanWindow is now enabling all Vulkan 1.0 features reported as  
supported from the physical device.  
  
* 2e2d544588 Fix clipped glyphs in text rendering of QGraphicsTextItem  
Clipping of visible glyphs when doing partial updates of a graphics  
view was off by 1. Also fixed an issue that caused rounding errors when  
transforming the clip rect into the glyphs draw space which was caused  
by transforming a QRect instead of a QRectF.  
  
* 44335e65bf Sequential erase/_if: don't apply predicate twice to  
element  
A fix in the implementation of the erase-like algorithms of sequential  
Qt container may re-enable signed/unsigned comparison warnings  
previously suppressed by having occurred in std library code. To fix,  
cast the value to look for such that it has the same signedness as the  
container's elements.  
  
* 899ab8f0df Fix C++20 ambiguous relational operators between  
QJsonValue{,Ref}  
Fixed relational operators to not cause warnings/ambiguities when  
compiling in C++20.  
  
* ab6915f0ef QProcess/Unix: ensure we don't accidentally execute  
something from CWD  
When passed a simple program name with no slashes, QProcess on Unix  
systems will now only search the current directory if "." is one of the  
entries in the PATH environment variable. This bug fix restores the  
behavior QProcess had before Qt 5.9. If launching an executable in the  
directory set by setWorkingDirectory() or inherited from the parent is  
intended, pass a program name starting with "./". For more information  
and best practices about finding an executable, see QProcess'  
documentation.  
  
* 4114c1163b QDesktopServices: fix ABA problem in  
QOpenUrlHandlerRegistry  
Fixed a bug where destroying and re-creating a handler object in quick  
succession could cause the registration for the handler to be lost.  
  
* 360f181857 configure: Allow specifying arbitrary variable assignments  
Users can directly assign CMake variables with configure, for example  
"configure CMAKE_CXX_COMPILE=clang++-11".  
  
* b3d1ea8530 QDesktopServices: deprecate destroying URL handlers w/o  
explicit unsetUrlHandler()  
URL handlers that have been passed to setUrlHandler() must now be  
removed by calling unsetUrlHandler() before they are destroyed. Relying  
on the handler's destructor to implicitly unset it is now deprecated,  
because it may already be in use by concurrent openUrl() calls. Support  
for implicit unsetting will be removed in 6.6 and, until then, a  
qWarning() is raised if it is exercised.  
  
* b3d19fbf95 QMetaObjectBuilder: fix addProperty() recording of the  
property type  
Fixed a bug that would cause addProperty() to use the incorrect type  
for the property if the property's name matched a valid type registered  
with QMetaType.  
  
### qttools  
* 5b641c12a Qt Designer: Enable the QWebEngineView, QQuickWidget plugins  
on Windows  
Qt Designer now sets the Graphics API to OpenGL in order to enable the  
QWebEngineView and QQuickWidget plugins.
