PulseAudio 4.0 Brings Many Changes

PulseAudio 4.0 is now available and with it comes many changes to this commonly used but sometimes controversial audio server.

Key changes to PulseAudio 4.0 include better handling of low-latency requests, optimization mixes (including ARM NEON optimizations), Bluetooth audio refactoring, improvements to the echno canceller infrastructure, Bash completion for command-line components, and lots of other enhancements.

For end-users, the optimization mixing, low-latency improvements, Bleutooth refactoring, JACK work, and echo canceller fixes seem to be the most notable changes.
