+Release note  
+============  
+  
+Qt 5.15.8 release is a patch release made on the top of Qt 5.15.7. As a patch  
+release, Qt 5.15.8 does not add any new functionality but provides bug fixes  
+and other improvements.  
+  
+For detailed information about Qt, see the Qt 5.15 online documentation:  
+https://doc.qt.io/qt-5/index.html.    
+  
+Important Changes  
+-----------------  
+  
+### qtbase  
+* 88f007f63a PCRE2: upgrade to 10.39  
+PCRE2 has been updated to version 10.39.  
+  
+* 12f13ac1ee qmake: Support Visual Studio 2022  
+Added support for Visual Studio 2022.  
+  
+* 1e763219a8 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.  
+  
+* 762084c492 QVERIFY_EXCEPTION_THROWN: re-throw unknown exceptions  
+Now re-throws unknown exceptions (= not derived from std::exception)  
+(was: swallowed them and returned from the test function), in order to  
+play nice with pthread cancellation.  
+  
+* 7ec94d2792 QSharedPointer: fix counter-productive QT_PREPEND_NAMESPACE  
+use in qHash() impl  
+The qHash(QSharedPointer<X>) overload can now use qHash(X*) overloads  
+found (only) through ADL (was: ADL was disabled due to qualified lookup  
+of qHash(X*)).  
+  
+* 8444b1ed1f QStringView: fix split(QRegularExpression) returning  
+invalid data  
+Fixed a bug where invalid references could be returned for  
+QString::fromRawData() subjects.  
+  
+* 26746e4361 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).  
+  
+* dad04e532b QVarLengthArray: fix size update on failed append()  
+Fixed a bug whereby a failed append() would leave the container with an  
+inconsistent size().  
+  
+* 97e56d4fa4 QVarLengthArray: fix UB (precondition violation) in range-  
+erase()  
+Fixed a bug where range-erase() could invoke undefined behavior when  
+called with an empty range.  
+  
+* a948c725e5 Fix missing characters or assert with certain font sizes  
+Fixed an issue where characters would in some rare cases be missing  
+from text, depending on font metrics, font size and system scale factor.  
+  
+### qtdeclarative  
+* 72e8cb6e1d Fix missing glyphs when changing distance field parameters  
+Fixed an issue where glyphs would sometimes be missing when changing  
+the environment variables that define how distance fields are generated  
+to certain values.  
+  
+* 03143a5e51 Fix Flickable wheel velocity calculation  
+Flickable no longer tries to detect whether you're using a "clicky"  
+wheel or a touchpad, but rather does the velocity calculation more  
+correctly with elapsed time (dθ / dt). A single rotation of a "clicky"  
+wheel also moves a fixed distance, which is now adjustable via  
+QStyleHints::wheelScrollLines(). Animation is restored, but should now  
+stay in control on touchpads; and it will once again transition the  
+"moving" properties correctly when scrolling ends.  
+  
+### qtlocation  
+* 45ff6ea6 Fix positioning must be enabled and authorized at startup to  
+work on iOS  
+Fix positioning must be enabled and authorized on startup to work on iOS  
+  
+### qtwayland  
+* 1887f6b4 Fix the logic for decoding modifiers map in Wayland text  
+input protocol  
+Fix modifiers map decoding logic when receiving the map from the  
+compositor.  
+  
+
