New feature releases are available for Phonon and Phonon-VLC. Both are very much centred around improving behavior with VLC 3.0 which introduced new API allowing correct roles being set on PulseAudio streams and as a result notification volume control is now actually working as expected. This also means automatic corking of music streams on voice calls can work correctly.
