This PR addresses all announced February 2026 changes to the Spotify API. All relevant functions and fields affected as detailed below have not been removed, but instead annotated with @SpotifyExtendedQuota since they remain functional if using client credentials with extended quota mode.

Restricted endpoints:

• Batch gets: GET /albums, /artists, /browse/categories, /episodes, /shows, /tracks
• Browse: GET /browse/new-releases, /browse/categories, /browse/categories/{id}
• Markets: GET /markets
• Artist: GET /artists/{id}/top-tracks
• User: GET /users/{id}/playlists, /users/{id}

(Audiobook & chapter APIs were restricted as well but are not reflected in this API at the moment)

Restricted fields:

• Album: album_group, available_markets, external_ids, label, popularity
• Artist: followers, popularity
• Show: available_markets, publisher
• Track: available_markets, external_ids, linked_from, popularity
• User: country, email, explicit_content, followers, product

Unified /me/library endpoint:

• Endpoints to add, remove, and check items /me/{albums|episodes|shows|tracks|albums} migrated to /me/library
• Endpoints to un/follow artists and users /me/following migrated to /me/library

Playlist changes:

• All tracks fields have been renamed to items. The old field names were kept but marked as deprecated for legacy accessibility
• All tracks endpoints have also migrated to items
• Playlist creation endpoint migrated from POST /users/{user_id}/playlists to POST /me/playlists

Older changes (2024):

In 2024, some endpoints were restricted to extended quota mode already, see announcement.
Relevant endpoint functions have also been annotated with @SpotifyExtendedQuota accordingly:

• Related artists: GET /artists/{id}/related-artists
• Recommendations: GET /recommendations
• Audio features/analysis: GET /audio-features/{id}, /audio-analysis/{id}
• Featured/Category playlists: GET /browse/featured-playlists, /browse/categories/{category_id}/playlists
• Removing playables from playlist at position (undocumented change)

Older changes (2025):

• Implicit grants are now marked as deprecated, see announcement

Updated tests

• Tests using restricted features are now @Ignored
• Fixed broken tests (references to deleted/unusable uris, usage of removed endpoints, etc)
• Updated Github workflow dependencies
