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

Qt 6.2.1 release is a patch release made on the top of Qt 6.2.0.  
As a patch release, Qt 6.2.1 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 6.2.0.  

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  
* 2a5a93a04d SQLite: Update SQLite to v3.36.0  
Updated SQLite to v3.36.0  
  
* 138d07dec7 OpenSSL: Let people opt-in to use TLS 1.3 PSK callback  
When using TLS 1.3 we suppress the first callback from OpenSSL about  
pre-shared keys, as it doesn't conform to the past behavior which  
preSharedKeyAuthenticationRequired provided. With this update you can  
opt-out of that workaround by setting the QT_USE_TLS_1_3_PSK environment  
variable  
  
* d11cbb5643 Fix querying font aliases that share name with other fonts  
Fixed an issue where some font styles and weights would not be  
selectable. This was especially noticeable on Windows.  
  
* 4acc17fa7f qSwap: make it constexpr  
qSwap is now constexpr.  
  
* 8d445e6c73 Use Yu Gothic UI as the main fallback font for Japanese  
Made the primary fallback font on Japanese locale "Yu Gothic UI" (the  
default system font).  
  
* c36932ef6f Update PCRE2 to 10.38  
PCRE2 has been updated to version 10.38.  
  
* fbaf6d0bdf Revert "Support family names that end/start with space"  
Fixed an assert that happened when the system had a font with a  
trailing or leading space in its name.  
  
* 8fbf61c323 freetype/no-fc: Disambiguate fonts with different widths  
Fixed a bug where fonts of different width within the same family would  
be unselectable if the Freetype font database (no-fontconfig  
configuration) was in use.  
  
### qtdeclarative  
* 93911fa45c Add button argument to the  
TapHandler.[single|double|]tapped signals  
TapHandler's tapped(), singleTapped() and doubleTapped() signals now  
have two arguments: the QEventPoint instance, and the button being  
tapped. If you need it, you should write an explicit function for the  
signal handler: onTapped: function(point, button) { ... } or  
onDoubleTapped: (point, button)=> ...  
  
* f51231164e QQmlEngine: Fine grained translation binding tracking  
QQmlEngine::retranslate no longer refreshes all bindings, but only  
translation bindings.
