3 Fixed building with JACK and without PulseAudio.
5 Fixed building on FreeBSD.
7 Fixed the ALSA backend's allow-resampler option.
9 Improved handling of inexact ALSA period counts.
11 Altered device naming scheme on Windows backends to better match other
14 Updated the CoreAudio backend to use the AudioComponent API. This fixes
15 deprecation warnings for OSX 10.11, although requires OSX 10.6 or newer.

23 Implemented the ALC_SOFT_HRTF extension.
25 Implemented C, SSE3, and SSE4.1 based 4- and 8-point Sinc resamplers.
27 Implemented a C and SSE based band-limited Sinc resampler. This does 12- to
28 24-point Sinc resampling, and performs anti-aliasing.
30 Implemented B-Format output support for the wave file writer. This creates
31 FuMa-style first-order Ambisonics wave files (AMB format).
33 Implemented a stereo-mode config option for treating stereo modes as either
34 speakers or headphones.
36 Implemented per-device configuration options.
38 Fixed handling of PulseAudio and MMDevAPI devices that have identical
41 Fixed a potential lockup when stopping playback of suspended PulseAudio devices.
43 Fixed logging of Unicode characters on Windows.
45 Fixed 5.1 surround sound channels. By default it will now use the side
46 channels for the surround output. A configuration using rear channels is
49 Fixed the QSA backend potentially altering the capture format.
51 Fixed detecting MMDevAPI's default device.
53 Fixed returning the default capture device name.
55 Fixed mixing property calculations when deferring context updates.
57 Altered the behavior of alcSuspendContext and alcProcessContext to better
58 match certain Windows drivers.
60 Altered the panning algorithm, utilizing Ambisonics for better side and
61 back positioning cues with surround sound output.
63 Improved support for certain older Windows apps.
65 Improved the alffplay example to support surround sound streams.
67 Improved support for building as a sub-project.
69 Added an HRTF playback example.
71 Added a tone generator output test.
73 Added a toolchain to help with cross-compiling to Android.
77 Implemented EFX Chorus, Flanger, Distortion, Equalizer, and Compressor
80 Implemented high-pass and band-pass EFX filters.
82 Implemented the high-pass filter for the EAXReverb effect.
84 Implemented SSE2 and SSE4.1 linear resamplers.
86 Implemented Neon-enhanced non-HRTF mixers.
88 Implemented a QSA backend, for QNX.
90 Implemented the ALC_SOFT_pause_device, AL_SOFT_deferred_updates,
91 AL_SOFT_block_alignment, AL_SOFT_MSADPCM, and AL_SOFT_source_length
94 Fixed resetting mmdevapi backend devices.
96 Fixed clamping when converting 32-bit float samples to integer.
98 Fixed modulation range in the Modulator effect.
100 Several fixes for the OpenSL playback backend.
102 Fixed device specifier names that have Unicode characters on Windows.
104 Added support for filenames and paths with Unicode (UTF-8) characters on
107 Added support for alsoft.conf config files found in XDG Base Directory
108 Specification locations (XDG_CONFIG_DIRS and XDG_CONFIG_HOME, or their
109 defaults) on non-Windows systems.
111 Added a GUI configuration utility (requires Qt 4.8).
113 Added support for environment variable expansion in config options (not
114 keys or section names).
116 Added an example that uses SDL2 and ffmpeg.
118 Modified examples to use SDL_sound.
120 Modified CMake config option names for better sorting.
122 HRTF data sets specified in the hrtf_tables config option may now be
123 relative or absolute filenames.
125 Made the default HRTF data set an external file, and added a data set for
126 48khz playback in addition to 44.1khz.
128 Added support for C11 atomic methods.
130 Improved support for some non-GNU build systems.
134 Fixed a regression with retrieving the source's AL_GAIN property.
138 Fixed device enumeration with the OSS backend.
140 Reorganized internal mixing logic, so unneeded steps can potentially be
141 skipped for better performance.
143 Removed the lookup table for calculating the mixing pans. The panning is
144 now calculated directly for better precision.
146 Improved the panning of stereo source channels when using stereo output.
148 Improved source filter quality on send paths.
150 Added a config option to allow PulseAudio to move streams between devices.
152 The PulseAudio backend will now attempt to spawn a server by default.
154 Added a workaround for a DirectSound bug relating to float32 output.
156 Added SSE-based mixers, for HRTF and non-HRTF mixing.
158 Added support for the new AL_SOFT_source_latency extension.
160 Improved ALSA capture by avoiding an extra buffer when using sizes
161 supported by the underlying device.
163 Improved the makehrtf utility to support new options and input formats.
165 Modified the CFLAGS declared in the pkg-config file so the "AL/" portion of
166 the header includes can optionally be omitted.
168 Added a couple example code programs to show how to apply reverb, and
171 The configuration sample is now installed into the share/openal/ directory
172 instead of /etc/openal.
174 The configuration sample now gets installed by default.
