+****************************************************************************
+* Important Behavior Changes *
+****************************************************************************
+
+ - QAudioOutput now transitions to IdleState instead of ActiveState when
+ calling resume() in push mode. This was already the documented behavior
+ but in practice, it was not respected on any platform. See QTBUG-50390.
+
+ - DirectShow is now the default backend on all desktop versions of Windows,
+ regardless of the compiler used. The Windows Media Foundation backend
+ (WMF) can be re-enabled by configuring Qt with the -wmf-backend option.
+ See QTBUG-45597.
