+****************************************************************************
+* Platform-specific Changes *
+****************************************************************************
+
+Linux
+-----
+
+ - [QTBUG-63584] Fixed a crash in evdev when multiple touchscreens are in use.
+
+Windows
+-------
+
+ - Fixed a compatibility issue found when linking code compiled with
+ MSVC version 16.6 to a Qt compiled with 16.5.

+****************************************************************************
+* QtCore *
+****************************************************************************
+
+ - QCborValue:
+ * fromCbor() now limits decoding to at most 1024 nested maps, arrays,
+ and tags to prevent stack overflows. This should be sufficient for
+ most uses of CBOR. An API to limit further or to relax the limit will
+ be provided in 5.15. Meanwhile, if decoding more is required,
+ QCborStreamReader can be used (note that each level of map and array
+ allocates memory).
+
+****************************************************************************
+* QtSQL *

+ - QImage:
+ * [oss-fuzz 22557] Fixed undefined behavior in bmp/ico decoder
