## [0.5.0-dev] - YYYY-MM-DD
2022-07-30 22:04:08 +00:00
This version will be a major departure from the architecture up until now. It
focuses on implementing the "new Spotify API". This means moving large parts
of the Spotify protocol from Mercury to HTTP. A lot of this was reverse
engineered before by @devgianlu of librespot-java. It was long overdue that we
started implementing it too, not in the least because new features like the
hopefully upcoming Spotify HiFi depend on it.
Splitting up the work on the new Spotify API, v0.5.0 brings HTTP-based file
downloads and metadata access. Implementing the "dealer" (replacing the current
Mercury-based SPIRC message bus with WebSockets, also required for social plays)
is separate large effort, to be targeted for v0.6.0.
While at it, we are taking the liberty to do some major refactoring to make
librespot more robust. Consequently not only the Spotify API changed but large
parts of the librespot API too. For downstream maintainers, we realise that it
can be a lot to move from the current codebase to this one, but believe us it
will be well worth it.
All these changes are likely to introduce new bugs as well as some regressions.
We appreciate all your testing and contributions to the repository:

## [0.4.2] - 2022-07-29
2022-05-21 20:52:39 +00:00
2022-07-30 22:04:08 +00:00
Besides a couple of small fixes, this point release is mainly to blacklist the
ap-gew4 and ap-gue1 access points that caused librespot to fail to playback
anything.
Development will now shift to the new HTTP-based API, targeted for a future
v0.5.0 release. The new-api branch will therefore be promoted to dev. This is a
major departure from the old API and although it brings many exciting new
things, it is also likely to introduce new bugs and some regressions.
Long story short, this v0.4.2 release is the most stable that librespot has yet
to offer. But, unless anything big comes up, it is also intended as the last
release to be based on the old API. Happy listening.

## [0.4.0] - 2022-05-21
2021-10-04 19:44:03 +00:00
2022-07-30 22:04:08 +00:00
Note: This version was yanked, because a corrupt package was uploaded and failed
to install.
This is a polishing release, adding a few little extras and improving on many
thers. We had to break a couple of API's to do so, and therefore bumped the
minor version number. v0.4.x may be the last in series before we migrate from
the current channel-based Spotify backend to a more HTTP-based backend.
Targeting that major effort for a v0.5 release sometime, we intend to maintain
v0.4.x as a stable branch until then.

- [discovery] The crate `librespot-discovery` for discovery in LAN was created. Its functionality was previously part of `librespot-connect` .
Implement dithering (#694)
Dithering lowers digital-to-analog conversion ("requantization") error, linearizing output, lowering distortion and replacing it with a constant, fixed noise level, which is more pleasant to the ear than the distortion.
Guidance:
- On S24, S24_3 and S24, the default is to use triangular dithering. Depending on personal preference you may use Gaussian dithering instead; it's not as good objectively, but it may be preferred subjectively if you are looking for a more "analog" sound akin to tape hiss.
- Advanced users who know that they have a DAC without noise shaping have a third option: high-passed dithering, which is like triangular dithering except that it moves dithering noise up in frequency where it is less audible. Note: 99% of DACs are of delta-sigma design with noise shaping, so unless you have a multibit / R2R DAC, or otherwise know what you are doing, this is not for you.
- Don't dither or shape noise on S32 or F32. On F32 it's not supported anyway (there are no integer conversions and so no rounding errors) and on S32 the noise level is so far down that it is simply inaudible even after volume normalisation and control.
New command line option:
--dither DITHER Specify the dither algorithm to use - [none, gpdf,
tpdf, tpdf_hp]. Defaults to 'tpdf' for formats S16
S24, S24_3 and 'none' for other formats.
Notes:
This PR also features some opportunistic improvements. Worthy of mention are:
- matching reference Vorbis sample conversion techniques for lower noise
