| **************************************************************************** |
| * 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. |
