CHANGELOG.md

@@ -6,14 +6,44 @@ The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/),
 and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html) since v0.2.0.
 
 ## [Unreleased]
+### Added
+- [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)
 
-### Removed
+### Changed
+- [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)
 
-* [librespot-audio] Removed `VorbisDecoder`, `VorbisError`, `AudioPacket`, `PassthroughDecoder`, `PassthroughError`, `AudioError`, `AudioDecoder` and the `convert` module from `librespot_audio`. The underlying crates `vorbis`, `librespot-tremor`, `lewton` and `ogg` should be used directly.
+### Deprecated
+- [connect] The `discovery` module was deprecated in favor of the `librespot-discovery` crate
 
-### Fixed
+### Removed
+- [connect] Removed no-op mixer started/stopped logic (breaking)
+- [playback] Removed `with-vorbis` and `with-tremor` features
+- [playback] `alsamixer`: removed `--mixer-linear-volume` option; use `--volume-ctrl linear` instead
 
-* [librespot-playback] Incorrect `PlayerConfig::default().normalisation_threshold` caused distortion when using dynamic volume normalisation downstream
+### Fixed
+- [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`: better error handling
