    Implemented the AL_SOFT_callback_buffer extension.
    Implemented the AL_SOFT_UHJ extension. This supports native UHJ buffer    formats and Super Stereo processing.

    Improved SoundIO capture behavior.
    Fixed UHJ output on NEON-capable CPUs.
    Fixed redundant effect updates when setting an effect property to the    current value.

    Added a PipeWire backend.
    Added enumeration for the JACK and CoreAudio backends.
    Added optional support for RTKit to get real-time priority. Only used as a    backup when pthread_setschedparam fails.
    Added an option for JACK playback to render directly in the real-time    processing callback. For lower playback latency, on by default.
    Added an option for custom JACK devices.
    Added utilities to encode and decode UHJ audio files. Files are decoded to    the .amb format, and are encoded from libsndfile-compatible formats.
    Added an in-progress extension to hold sources in a playing state when a    device disconnects. Allows devices to be reset or reopened and have sources    resume from where they left off.
    Lowered the priority of the JACK backend. To avoid it getting picked when    PipeWire is providing JACK compatibility, since the JACK backend is less    robust with auto-configuration.

    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.
