+openal-soft-1.21.1:
+
+    Improved alext.h's detection of standard types.
+
+    Improved slightly the local source position when the listener and source
+    are near each other.
+
+    Fixed compilation for Windows ARM targets with MSVC.
+
+    Fixed ARM NEON detection on Windows.
+
+    Fixed CoreAudio capture when the requested sample rate doesn't match the
+    system configuration.
+
+    Fixed OpenSL capture desyncing from the internal capture buffer.
+
+    Fixed sources missing a batch update when applied after quickly restarting
+    the source.
+
+    Fixed missing source stop events when stopping a paused source.
+
+openal-soft-1.21.0:
+
+    Updated library codebase to C++14.
+
+    Implemented the AL_SOFT_effect_target extension.
+
+    Implemented the AL_SOFT_events extension.
+
+    Implemented the ALC_SOFT_loopback_bformat extension.
+
+    Improved memory use for mixing voices.
+
+    Improved detection of NEON capabilities.
+
+    Improved handling of PulseAudio devices that lack manual start control.
+
+    Improved mixing performance with PulseAudio.
+
+    Improved high-frequency scaling quality for the HRTF B-Format decoder.
+
+    Improved makemhr's HRIR delay calculation.
+
+    Improved WASAPI capture of mono formats with multichannel input.
+
+    Reimplemented the modulation stage for reverb.
+
+    Enabled real-time mixing priority by default, for backends that use the
+    setting. It can still be disabled in the config file.
+
+    Enabled dual-band processing for the built-in quad and 7.1 output decoders.
+
+    Fixed a potential crash when deleting an effect slot immediately after the
+    last source using it stops.
+
+    Fixed building with the static runtime on MSVC.
+
+    Fixed using source stereo angles outside of -pi...+pi.
+
+    Fixed the buffer processed event count for sources that start with empty
+    buffers.
+
+    Fixed trying to open an unopenable WASAPI device causing all devices to
+    stop working.
+
+    Fixed stale devices when re-enumerating WASAPI devices.
+
+    Fixed using unicode paths with the log file on Windows.
+
+    Fixed DirectSound capture reporting bad sample counts or erroring when
+    reading samples.
+
+    Added an in-progress extension for a callback-driven buffer type.
+
+    Added an in-progress extension for higher-order B-Format buffers.
+
+    Added an in-progress extension for convolution reverb.
+
+    Added an experimental Oboe backend for Android playback. This requires the
+    Oboe sources at build time, so that it's built as a static library included
+    in libopenal.
+
+    Added an option for auto-connecting JACK ports.
+
+    Added greater-than-stereo support to the SoundIO backend.
+
+    Modified the mixer to be fully asynchronous with the external API, and
+    should now be real-time safe. Although alcRenderSamplesSOFT is not due to
+    locking to check the device handle validity.
+
+    Modified the UHJ encoder to use an all-pass FIR filter that's less harmful
+    to non-filtered signal phase.
+
+    Converted examples from SDL_sound to libsndfile. To avoid issues when
+    combining SDL2 and SDL_sound.
+
+    Worked around a 32-bit GCC/MinGW bug with TLS destructors. See:
+    https://gcc.gnu.org/bugzilla/show_bug.cgi?id=83562
+
+    Reduced the maximum number of source sends from 16 to 6.
+
+    Removed the QSA backend. It's been broken for who knows how long.
+
+    Got rid of the compile-time native-tools targets, using cmake and global
+    initialization instead. This should make cross-compiling less troublesome.
+
+openal-soft-1.20.1:
+
+    Implemented the AL_SOFT_direct_channels_remix extension. This extends
+    AL_DIRECT_CHANNELS_SOFT to optionally remix input channels that don't have
+    a matching output channel.
+
+    Implemented the AL_SOFT_bformat_ex extension. This extends B-Format buffer
+    support for N3D or SN3D scaling, or ACN channel ordering.
+
+    Fixed a potential voice leak when a source is started and stopped or
+    restarted in quick succession.
+
+    Fixed a potential device reset failure with JACK.
+
+    Improved handling of unsupported channel configurations with WASAPI. Such
+    setups will now try to output at least a stereo mix.
+
+    Improved clarity a bit for the HRTF second-order ambisonic decoder.
+
+    Improved detection of compatible layouts for SOFA files in makemhr and
+    sofa-info.
+
+    Added the ability to resample HRTFs on load. MHR files no longer need to
+    match the device sample rate to be usable.
+
+    Added an option to limit the HRTF's filter length.
+
+openal-soft-1.20.0:
+
+    Converted the library codebase to C++11. A lot of hacks and custom
+    structures have been replaced with standard or cleaner implementations.
+
+    Partially implemented the Vocal Morpher effect.
+
+    Fixed the bsinc SSE resamplers on non-GCC compilers.
+
+    Fixed OpenSL capture.
+
+    Fixed support for extended capture formats with OpenSL.
+
+    Fixed handling of WASAPI not reporting a default device.
+
+    Fixed performance problems relating to semaphores on macOS.
+
+    Modified the bsinc12 resampler's transition band to better avoid aliasing
+    noise.
+
+    Modified alcResetDeviceSOFT to attempt recovery of disconnected devices.
+
+    Modified the virtual speaker layout for HRTF B-Format decoding.
+
+    Modified the PulseAudio backend to use a custom processing loop.
+
+    Renamed the makehrtf utility to makemhr.
+
+    Improved the efficiency of the bsinc resamplers when up-sampling.
+
+    Improved the quality of the bsinc resamplers slightly.
+
+    Improved the efficiency of the HRTF filters.
+
+    Improved the HRTF B-Format decoder coefficient generation.
+
+    Improved reverb feedback fading to be more consistent with pan fading.
+
+    Improved handling of sources that end prematurely, avoiding loud clicks.
+
+    Improved the performance of some reverb processing loops.
+
+    Added fast_bsinc12 and 24 resamplers that improve efficiency at the cost of
+    some quality. Notably, down-sampling has less smooth pitch ramping.
+
+    Added support for SOFA input files with makemhr.
+
+    Added a build option to use pre-built native tools. For cross-compiling,
+    use with caution and ensure the native tools' binaries are kept up-to-date.
+
+    Added an adjust-latency config option for the PulseAudio backend.
+
+    Added basic support for multi-field HRTFs.
+
+    Added an option for mixing first- or second-order B-Format with HRTF
+    output. This can improve HRTF performance given a number of sources.
+
+    Added an RC file for proper DLL version information.
+
+    Disabled some old KDE workarounds by default. Specifically, PulseAudio
+    streams can now be moved (KDE may try to move them after opening).
+
+openal-soft-1.19.1:
+
+    Implemented capture support for the SoundIO backend.
+
+    Fixed source buffer queues potentially not playing properly when a queue
+    entry completes.
+
+    Fixed possible unexpected failures when generating auxiliary effect slots.
+
+    Fixed a crash with certain reverb or device settings.
+
+    Fixed OpenSL capture.
+
+    Improved output limiter response, better ensuring the sample amplitude is
+    clamped for output.
+
 openal-soft-1.19.0:
 
     Implemented the ALC_SOFT_device_clock extension.
 
-    Implemented the Pitch Shifter effect.
+    Implemented the Pitch Shifter, Frequency Shifter, and Autowah effects.

     Increased the number of virtual channels for decoding Ambisonics to HRTF
