Changelog
This changelog is used to track all major changes to Mopidy.
For older releases, see History.
v4.0.0 (UNRELEASED)
Mopidy 4.0 is a backward-incompatible release because we’ve dropped support for old versions of our dependencies and a number of deprecated APIs.
Dependencies
- Python >= 3.11 is now required. Support for 3.7-3.10 have been dropped, while Python 3.13 has been included in the testing matrix. 
- GStreamer >= 1.22.0 is now required. 
- PyGObject >= 3.42 is now an explicit Python dependency, and not something we assume you’ll install together with GStreamer. 
- Pykka >= 4.0 is now required. 
- Requests >= 2.28 is now required. 
- Setuptools >= 66 is now required. 
- Tornado >= 6.2 is now required. 
- Replaced - pkg_resourceswith- importlib.metadatafrom Python’s standard library.
Core API
Changes to the Core API may affect Mopidy clients.
Some of the changes in the Core API are related to replacing the use of
full TlTrack objects as API arguments with tracklist IDs, tlid.
This is especially relevant for remote clients, like web clients, which may
pass a lot less data over the network when using tracklist IDs in API calls.
Root object
- The - mopidy.core.Coreclass now requires the config argument to be present. As this argument is provided by Mopidy itself at runtime, this should only affect the setup of extension’s test suites.
Library controller
- No changes so far. 
Playback controller
- mopidy.core.PlaybackController.play()no longer accepts- TlTrackobjects, which has been deprecated since Mopidy 3.0. Use tracklist IDs (- tlid) instead. (Fixes #1855, PR: #2150)
Playlist controller
- No changes so far. 
Tracklist controller
- No changes so far. 
Backend API
Changes to the Backend API may affect Mopidy backend extensions.
- Added - mopidy.backend.LibraryProvider.lookup_many()to take a list of URIs and return a mapping of URIs to tracks. If this method is not implemented then repeated calls to- mopidy.backend.LibraryProvider.lookup()will be used as a fallback.
- Deprecated - mopidy.backend.LibraryProvider.lookup(). Extensions should implement- mopidy.backend.LibraryProvider.lookup_many()instead.
Models
Changes to the data models may affect any Mopidy extension or client.
- The - mopidy.models.ImmutableObjectclass has been removed. Mopidy itself replaced this class with another implementation in v1.0.5 nine years ago.
Audio API
Changes to the Audio API may affect a few Mopidy backend extensions.
- Removed APIs only used by Mopidy-Spotify’s bespoke audio delivery mechanism, which has not been used since Spotify shut down their libspotify APIs in May 2022. The removed functions/methods are: - mopidy.audio.Audio.emit_data()
- mopidy.audio.Audio.set_appsrc()
- mopidy.audio.Audio.set_metadata()
- mopidy.audio.calculate_duration()
- mopidy.audio.create_buffer()
- mopidy.audio.millisecond_to_clocktime()
 
Extension support
- The command mopidy deps no longer repeats transitive dependencies that have already been listed. This reduces the length of the command’s output drastically. (PR: #2152) 
Internals
- Dropped split between the - mainand- developbranches. We now use- mainfor all development, and have removed the- developbranch.
- Added type hints to most of the source code. 
- Switched from mypy to pyright for type checking. 
v3.4.2 (2023-11-01)
- Deps: Python 3.11 and 3.12 are now included in the testing matrix. 
- M3U: Stop following symlinks when - file/follow_symlinksis false. (PR: #2094)
- zeroconf: Fix exception on shutdown if dbus is not installed. 
- Docs: Fix crash when building docs on recent Sphinx versions. 
- Dev: Make stacktraces from deprecation warnings include the offending call site, to help upgrade API usage in extensions. 
- Dev: Upgrade CI workflows to fix Node.js 12 deprecation notices and avoid Codecov’s bash uploader. 
- Dev: Make tests pass on macOS. (PR: #2092) 
- Dev: Incease test coverage of Mopidy-File to 100%. (PR: #2096) 
- Dev: Added - "tox -e ci”, to allow easy CI check before- git push.

- File: Fix uppercase - file/excluded_file_extensions. (PR: #2063)
- Add - mopidy.backend.PlaybackProvider.on_source_setup()which can be implemented by Backend playback providers that want to set GStreamer source properties in the- source-setupcallback. (PR: #2060)
- HTTP: Improve handling of - http/allowed_originsconfig setting. (PR: #2054)
v3.3.0 (2022-04-29)

- Core: Align values supported by the - fieldargument to- mopidy.core.LibraryController.get_distinct()with Mopidy search query fields, with the exception of ‘any’. Deprecated field ‘track’ with the goal of removing it in the next major release, use ‘track_name’ instead. Backends should support both track and track_name until they require a version of Mopidy where track has been removed. (Fixes: #1900, PR: #1899)
- Core: Add - musicbrainz_albumid,- musicbrainz_artistid,- musicbrainz_trackid, and- disc_noto the permitted search query fields. (Fixes: #1900, PR: #1899)

- Audio: Fix memory leak when converting GStreamer - sampletype tags. (Fixes: #1827, PR: #1929)
- Turn off strict parsing of - *.plsplaylist files. This was a regression that happened during the migration to Python 3. (PR: #1923)
- Make the systemd unit that ships with Mopidy wait for an Internet connection before starting Mopidy. When used by distribution packages, this can help avoid that extensions try to connect to cloud services before the machine’s Internet connection is ready for use. (PR: #1946)

v3.0.1 (2019-12-22)
Bugfix release.
v3.0.0 (2019-12-22)
The long-awaited Mopidy 3.0 is finally here, just in time for the Mopidy project’s 10th anniversary on December 23rd!
Mopidy 3.0 is a backward-incompatible release in a pretty significant way: Mopidy no longer runs on Python 2.
Mopidy 3.0 requires Python 3.7 or newer.
While extensions have been able to continue working without changes throughout the 1.x and 2.x series of Mopidy, this time is different:
- All extensions must be updated to work on Python 3.7 and newer. 
- Some extensions need to replace their use of a few long-deprecated APIs that we’ve removed. See below for details. 
- Extension maintainers are also encouraged to update their project’s setup to match our refreshed extension cookiecutter. 
In parallel with the development of Mopidy 3.0, we’ve coordinated with a few extension maintainers and upgraded almost 20 of the most popular extensions. These will all be published shortly after the release of Mopidy 3.0.
We’ve also built a new extension registry, where you can quickly track what extensions are ready for Python 3.
In other news, the Mopidy-MPD and Mopidy-Local extensions have grown up and moved out to flourish as independent extension projects. After the move, Mopidy-Local merged with Mopidy-Local-SQLite and Mopidy-Local-Images, which are now both a part of the Mopidy-Local extension.
Dependencies
- Python >= 3.7 is now required. Python 2.7 is no longer supported. 
- GStreamer >= 1.14.0 is now required. 
- Pykka >= 2.0.1 is now required. 
- Tornado >= 4.4 is now required. The upper boundary (< 6) has been removed. 
- We now use a number of constants and functions from - GLibinstead of their deprecated equivalents in- GObject. The exact version of PyGObject and GLib that makes these constants and functions available in the new location is not known, but is believed to have been released in 2015 or earlier.
Logging
- The command line option - mopidy --save-debug-logand the configuration- logging/debug_filehave been removed. To save a debug log for sharing, run- mopidy -vvvv 2>&1 | tee mopidy.logor equivalent. (Fixes: #1452, PR: #1783)
- Replaced the configurations - logging/console_formatand- logging/debug_formatwith the single configuration- logging/format. It defaults to the same format as the old debug format. (Fixes: #1452, PR: #1783)
- Added configuration - logging/verbosityto be able to control logging verbosity from the configuration file, in addition to passing- -qor- -von the command line. (Fixes: #1452, PR: #1783)
Core API
- Removed properties, methods, and arguments that have been deprecated since 1.0, released in 2015. Everything removed already has a replacement, that should be used instead. See below for a full list of removals and replacements. (Fixes: #1083, #1461, PR: #1768, #1769) 
Root object
- Removed properties, use getter/setter instead: - mopidy.core.Core.uri_schemes

Library controller
- Removed methods: - mopidy.core.LibraryController.find_exact(): Use- search()with the keyword argument- exact=Trueinstead.
 
- Removed the - uriargument to- mopidy.core.LibraryController.lookup(). Use the- urisargument instead.
- Removed the support for passing the search query as keyword arguments to - mopidy.core.LibraryController.search(). Use the- queryargument instead.
- mopidy.core.LibraryController.search()now returns an empty result if there is no- query. Previously, it returned the full music library. This is not feasible for online music services and has thus been deprecated since 1.0.
Playback controller
- Removed properties, use getter/setter instead: - mopidy.core.PlaybackController.current_tl_track
- mopidy.core.PlaybackController.current_track
- mopidy.core.PlaybackController.state
- mopidy.core.PlaybackController.time_position
 
- Moved to the mixer controller: - mopidy.core.PlaybackController.get_mute(): Use- get_mute().
- mopidy.core.PlaybackController.get_volume(): Use- get_volume().
- mopidy.core.PlaybackController.set_mute(): Use- set_mute().
- mopidy.core.PlaybackController.set_volume(): Use- set_volume().
- mopidy.core.PlaybackController.mute: Use- get_mute()and- set_mute().
- mopidy.core.PlaybackController.volume: Use- get_volume()and- set_volume().
 
- Deprecated the - tl_trackargument to- mopidy.core.PlaybackController.play(), with the goal of removing it in the next major release. Use the- tlidargument instead. (Fixes: #1773, PR: #1786, #1854)
Playlist controller
- Removed properties, use getter/setter instead: - mopidy.core.PlaylistController.playlists
 
- Removed methods: - mopidy.core.PlaylistsController.filter(): Use- as_list()and filter yourself.
- mopidy.core.PlaylistsController.get_playlists(): Use- as_list()and- get_items().
 
Tracklist controller
- Removed properties, use getter/setter instead: - mopidy.core.TracklistController.tl_tracks
- mopidy.core.TracklistController.tracks
- mopidy.core.TracklistController.length
- mopidy.core.TracklistController.version
- mopidy.core.TracklistController.consume
- mopidy.core.TracklistController.random
- mopidy.core.TracklistController.repeat
- mopidy.core.TracklistController.single
 
- Removed the - uriargument to- mopidy.core.TracklistController.add(). Use the- urisargument instead.
- Removed the support for passing filter criteria as keyword arguments to - mopidy.core.TracklistController.filter(). Use the- criteriaargument instead.
- Removed the support for passing filter criteria as keyword arguments to - mopidy.core.TracklistController.remove(). Use the- criteriaargument instead.
- Deprecated methods, with the goal of removing them in the next major release: (Fixes: #1773, PR: #1786, #1854) - mopidy.core.TracklistController.eot_track(). Use- get_eot_tlid()instead.
- mopidy.core.TracklistController.next_track(). Use- get_next_tlid()instead.
- mopidy.core.TracklistController.previous_track(). Use- get_previous_tlid()instead.
 
- The - tracksargument to- mopidy.core.TracklistController.add()has been deprecated since Mopidy 1.0. It is still deprecated, with the goal of removing it in the next major release. Use the- urisargument instead.
Backend API
- Add - mopidy.backend.PlaybackProvider.is_live()which can be implemented by playback providers that want to mark their URIs as live streams that should not be buffered. (PR: #1845)
Models
- Remove - .copy()method on all model classes. Use the- .replace()method instead. (Fixes: #1464, PR: #1774)
- Remove - mopidy.models.Album.images. Clients should use- mopidy.core.LibraryController.get_images()instead. Backends should implement- mopidy.backend.LibraryProvider.get_images(). (Fixes: #1464, PR: #1774)
Extension support
- The following methods now return - pathlib.Pathobjects instead of strings:- This makes it easier to support arbitrary encoding in file names. 
- The command mopidy deps no longer repeats the dependencies of Mopidy itself for every installed extension. This reduces the length of the command’s output drastically. (PR: #1846) 
HTTP frontend
- Stop bundling Mopidy.js and serving it at - /mopidy/mopidy.jsand- /mopidy/mopidy.min.js. All Mopidy web clients must use Mopidy.js from npm or vendor their own copy of the library. (Fixes: #1083, #1460, PR: #1708)
- Remove support for serving arbitrary files over HTTP through the use of - http/static_dir, which has been deprecated since 1.0. (Fixes: #1463, PR: #1706)
- Add option - http/default_appto redirect from web server root to a specific app instead of Mopidy’s web app list. (PR: #1791)
- Add cookie secret to Tornado web server, allowing Tornado request handlers to call - get_secure_cookie(), in an implementation of- get_current_user(). (PR: #1801)
MPD frontend
- The Mopidy-MPD frontend is no longer bundled with Mopidy, and has been moved to its own Git repo and PyPI project. 
Local backend
- The Mopidy-Local backend is no longer bundled with Mopidy, and has been moved to its own Git repo and PyPI project. (Fixes: #1003) 
- Removed - mopidy.exceptions.FindError, as it was only used by Mopidy-Local. (PR: #1857)
Audio
- Remove the method - mopidy.audio.Audio.emit_end_of_stream(), which has been deprecated since 1.0. (Fixes: #1465, PR: #1705)
- Add - live_streamoption to- mopidy.audio.Audio.set_uri()that disables buffering, which reduces latency before playback starts, and discards data when paused. (PR: #1845)
Internals
- Format code with Black. (PR: #1834) 
- Port test assertions from - unittestmethods to pytest- assertstatements. (PR: #1838)
- Switch all internal path handling to use - pathlib. (Fixes: #1744, PR: #1814)
- Remove - mopidy.compatand all Python 2/3 compatibility code. (PR: #1833, #1835)
