[pulseaudio-discuss] [ANNOUNCE] PulseAudio 4.0

[Arun Raghavan]

Hello folks,
We're back, with another exciting episode of PulseAudio Releases!

There's just a minor OS X fix since 3.99.2, and a NEWS file to make the
tarballs more user-friendly. From 3.0, notable changes include:

  * Better handling of low latency requests
  * Optimisations while mixing (generic, ARM NEON)
  * Default resampler is now speex-float-1 (lower CPU usage)
  * Major Bluetooth refactoring for better reliability and easier
maintenance
  * Fixes for graceful hand-off to/from JACK
  * New module to apply ducking based on stream roles
  * Echo canceller infrastructure fixes
  * Bash and zsh completion for command line tools
  * Solaris and OS X fixes
  * Lots of other enhancements, bug fixes, and documenation and i18n
updates

Tanu's written a much more detailed and excellent summary of the changes
at:

Tarball, as usual, is at:

SHA1: 9f0769dcb25318ba3faaa453fd2ed0c509fa9c5c

We continue to see a steady influx of patches from old and new
contributors, and big thanks go out to all of you! Special shout-out to
Mikel Astiz for his patient work on the Bluetooth modules.

Shortlog follows as usual, but the detailed change log linked above is
even better!

Cheers,
Arun
