Features

phonon4qt5 is a feature and API equivalent library built against Qt 5 rather than Qt 4. Phonon4Qt5 is built from the same source; requires the cmake option PHONON_BUILD_PHONON4QT5 and a separate build directory from Qt 4.
(( qt5 qmake integreation qt5_phonon.pri (how to use?) .... how to use in qt4?
MediaSource(QString) is now deprecated, MediaSource(QUrl) should be used instead.
New build option PHONON_ASSERT_STATES to debug incoherent or incorrect state changes from the backend.
Documentation cleanup.
Normalized internal QObject connections.
Experimental qmake support; limited control over feature set and installation path.
By default both official Phonon backends try to find a matching subtitle file for videos.

New AudioOutputInterface47 allowing backends to get the Phonon Pulseaudio stream mapping ID which can be used together with PulseSupport::streamProperties to prevent #321288. Requires PHONON_BACKEND_VERSION_4_7 to be defined as with all new interface versions.

AudioOutput::setVolume can now be called before entering Phonon::Playing state regardless of whether PulseAudio is in use or not #321172.
Consecutive streams no longer override each other's PulseAudio stream mapping #321288.
