Release note  
============  

Qt 6.2.2 release is a patch release made on the top of Qt 6.2.1.  
As a patch release, Qt 6.2.2 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 6.2.1.  

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  
* 448e45b1f4 QVarLengthArray: Reduce memory allocations in insert()  
Reduced number of memory allocations in insert() by allocating more  
memory at once.  
  
* b4b3343b80 PCRE2: upgrade to 10.39  
PCRE2 has been updated to version 10.39.  
  
* 069dfef5e8 QByteArrayList: fix narrowing in join() implementations  
[1/2]  
Fixed a bug when calling join() on lists with more than INTMAX  
elements.  
  
* de2395d757 qmake: Support Visual Studio 2022  
Added support for Visual Studio 2022.  
  
* 94016862a7 QImageReader: check allocation limit for minimum 32 bpp  
When checking allocation limit during image reading, the memory  
requirements are now calculated for a minimum of 32 bits per pixel,  
since Qt will typically convert an image to that depth when it is used  
in GUI. This means that the effective allocation limit is significantly  
smaller when reading 1 bpp and 8 bpp images.  
  
### qtdeclarative  
* 092f2c4f61 Fix distorted text with subpixel matrix translation  
Fixed an issue where text using NativeRendering would look slightly  
skewed if it was inside a parent that had been positioned at a subpixel  
offset.  
  
* f44aabad32 Use correct plugin name for Android QML plugins  
Starting with Qt 6.4, QML import mechanism won't add URI-based prefixes  
when looking for QML plugins for Android applications. For forward  
compatibility, the 'plugin' record of the qmldir files should contain  
the full file name of the plugin without abi-specific suffixes and the  
file extension. When using the CMake API to create the qmldir, no  
further action is necessary.  
  
### qtwayland  
* 60f908ba Fix the logic for decoding modifiers map in Wayland text  
input protocol  
Fix modifiers map decoding logic when receiving the map from the  
compositor.  
  
### qtvirtualkeyboard  
* d897a740 cerence-hwr: Fix compilation with the latest Cerence SDK (v9)  
Added support for the latest Cerence SDK (9.x).  
  
* 2b84f3b1 Use a containment mask to keep input panel working during  
modal session  
Since Qt 5.15, the virtual keyboard's input panel has automatically  
been reparented to prevent the keyboard UI from being blocked by modal  
dialogs. This is no longer done; the input panel instead uses a  
containment mask on the dimmer item that blocks input during modal  
sessions, allowing clicks through to the keyboard UI.
