+Release note  
+============  
+  
+Qt 6.4.1 release is a patch release made on the top of Qt 6.4.0.  
+As a patch release, Qt 6.4.1 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 6.4.0.  
+
+For detailed information about Qt 6.4, 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 6.4 series is binary compatible with the 6.3.x series.  
+Applications compiled for 6.3 will continue to run with 6.4.  
+  
+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  
+* d7620f1b74 Fix crash when setting override cursor on multiple clients  
+Fixed a crash when setting an override cursor on multiple clients.  
+  
+* 75a9a0ad5e Update bundled libjpeg-turbo to version 2.1.4  
+libjpeg-turbo was updated to version 2.1.4  
+  
+* b627f51978 Document QAtomic testAndSet  
+Documented new overloads of testAndSet() that were originally added for  
+5.3.  
+  
+* 1cb57091ac Revert "Keep original text for text/plain mime data"  
+The fix to preserve special characters like   the text/plain part  
+of the clipboard when copied from a QTextEdit or QLineEdit had to be  
+reverted (QTBUG-107004).  
+  
+* ed3d60cfca QTaggedPointer: disable operator= with an empty initializer  
+list  
+The operator assignment taking a raw pointer has been reimplemented in  
+order to avoid subtle issues when assigning `{}` to a QTaggedPointer.  
+This will cause code that assigns a braced-init-list to a QTaggedPointer  
+object to stop compiling (for instance, `tagPtr = {ptr}` is now ill-  
+formed).  
+  
+* a111c15c0a Skip early return from test loops during cleanup()  
+During the cleanup() phase of a test, the QTRY_* macros and  
+QTestEventLoop now ignore the test resolution, in contrast to when they  
+are used from the test itself, which (since 6.3.0) exits the loops early  
+if the test has failed.  
+  
+* 9ac433b40a Fix generating PDFs with DirectWrite engine  
+Fixed glitches in generated PDFs when the DirectWrite backend was in  
+use, e.g. when high-dpi scaling was active.  
+  
+* c0b54bf6fa macOS: Fix less common writing systems on Catalina and  
+later  
+Fixed missing text with certain writing systems on macOS Catalina and  
+later.  
+  
+* c2f85da3be Update bundled libpng to version 1.6.38  
+libpng was updated to version 1.6.38  
+  
+* e0fea817a5 QBenchlib/Perf: don't try to benchmark the kernel  
+Fixed support of Linux performance counters for QBENCHMARK, which used  
+to fail with "Permission denied" errors in default configurations. Now,  
+QtTest will automatically fall back to profiling only userspace, like  
+the perf(1) tool does.  
+  
+### qtdeclarative  
+* ef6fe3e499 DA: ignore disabled HoverHandlers when delivering hover  
+events  
+Disabled hover handlers will no longer receive hover events, or block  
+siblings from being hovered.  
+  
+### qttools  
+* 838f8e2e0 QDoc: Remove the "\newcode" and "\oldcode" command pair  
+The deprecated \oldcode, \newcode commands were removed.  
+  
+* ab89fee0b qdoc: Enable correct linking to externally-built  
+dependencies  
+  
+  
+### qt5compat  
+* 16774f1 Avoid recreating gaussian blur shader multiple times  
+Improve creation time of Gaussian Blur-based effects.  
+  
+  
+Fixes  
+-----
