The changes from 1.5 include:
* Channel volumes are now ramped from source position changes and when
starting playback, to help prevent pops and clicks
* The AL_DOPPLER_FACTOR source property works
* Implemented a new Solaris backend for playback
* The openal-info example will now print EFX information
* More EFX compliance fixes
* Support for non-mmap ALSA capture
* A new low-pass filter, based on the I3DL2 specification
* The ALSOFT_CONF environment variable may be used to specify an additional
configuration file
* A completely new reverb effect implementation
* Improved CPU use for the DirectSound backend
Reproducible: Always
Steps to Reproduce:
I installed this version through my local overlay and tested it with three
games depending on openal without any problems.
Copying over the existing 1.5.304 ebuild should be sufficient.
