Tracks
- Track.IsPublished (migration marks existing tracks as published). New
tracks are created unpublished.
- PUT /tracks/{id}/published and PUT /tracks/published change the flag;
publishing requires completed audio processing (the batch endpoint
reports skipped tracks).
- An unpublished track is only visible to its owner. A WherePublished /
VisibleTo filter is applied to search, genres, listening history, last
listened, likes, mixes, album and playlist contents and counts, recently
listened albums, public user tracks, track details and stream tickets.
- isPublished is part of the track responses, GET /tracks/users/{userId}
accepts a published filter and status-counts reports published and
unpublished totals.
- CreateTrackRequest.pictureIntentId is optional: without it the track
uses the album cover or the preset picture and no picture processing
runs. CreateTrackResourcesEvent carries nullable picture fields, so
queues must be drained before deploying.
- POST /tracks/upload-urls accepts an audios list and one optional picture
shared by all of them, and returns an intent per file. The upload intent
limits are raised so a batch fits.
Albums
- AlbumType (Album, EP, Single) on create, update and responses.
- CreateAlbumRequest.trackIds creates the album and links the tracks in a
single save.
