+-----------
+
+ - Fixed a memory leak in QBluetoothServiceDiscoveryAgent on Android.
+
+ - [QTBUG-75035] Improved likelihood of
+   QBluetoothSocket::connectToService(QBluetoothServiceInfo,..) succeeding when
+   QBluetoothServiceInfo::socketProtocol() returns a non-RFCOMM type. Since Android
+   does not support anything but RFCOMM it always assumes RFCOMM.
+
+ - Fixed reading of descriptor values on WinRT.
+
+ - [QTBUG-75043] Fixed behavior when a peripheral changes its service list at runtime
+
+ - [QTBUG-75278] Fixed socket leak when running QLowEnergyController Peripheral mode
+   on Linux.
