Unreleased

[discovery] The crate librespot-discovery for discovery in LAN was created. Its functionality was previously part of librespot-connect.
[playback] Add support for dithering with --dither for lower requantization error (breaking)
[playback] Add --volume-range option to set dB range and control log and cubic volume control curves
[playback] alsamixer: support for querying dB range from Alsa softvol
[playback] Add --format F64 (supported by Alsa and GStreamer only)

[audio, playback] Moved VorbisDecoder, VorbisError, AudioPacket, PassthroughDecoder, PassthroughError, AudioError, AudioDecoder and the convert module from librespot-audio to librespot-playback. The underlying crates vorbis, librespot-tremor, lewton and ogg should be used directly. (breaking)
[audio, playback] Use Duration for time constants and functions (breaking)
[connect, playback] Moved volume controls from librespot-connect to librespot-playback crate
[connect] Synchronize player volume with mixer volume on playback
[playback] Store and pass samples in 64-bit floating point
[playback] Make cubic volume control available to all mixers with --volume-ctrl cubic
[playback] Normalize volumes to [0.0..1.0] instead of [0..65535] for greater precision and performance (breaking)
[playback] alsamixer: complete rewrite (breaking)
[playback] alsamixer: query card dB range for the log volume control unless specified otherwise
[playback] alsamixer: use --device name for --mixer-card unless specified otherwise
[playback] player: consider errors in sink.start, sink.stop and sink.write fatal and exit(1) (breaking)
[playback] player: make convert and decoder public so you can implement your own Sink

[connect] The discovery module was deprecated in favor of the librespot-discovery crate
[playback] alsamixer: renamed mixer-card to alsa-mixer-device
[playback] alsamixer: renamed mixer-name to alsa-mixer-control
[playback] alsamixer: renamed mixer-index to alsa-mixer-index

[connect] Removed no-op mixer started/stopped logic (breaking)
[playback] Removed with-vorbis and with-tremor features
[playback] alsamixer: removed --mixer-linear-volume option, now that --volume-ctrl {linear|log} work as expected on Alsa

[connect] Fix step size on volume up/down events
[playback] Incorrect PlayerConfig::default().normalisation_threshold caused distortion when using dynamic volume normalisation downstream
[playback] Fix log and cubic volume controls to be mute at zero volume
[playback] Fix S24_3 format on big-endian systems
[playback] alsamixer: make cubic consistent between cards that report minimum volume as mute, and cards that report some dB value
[playback] alsamixer: make --volume-ctrl {linear|log} work as expected
[playback] alsa, gstreamer, pulseaudio: always output in native endianness
[playback] alsa: revert buffer size to ~500 ms
[playback] alsa, pipe, pulseaudio: better error handling
