Dec 1, 2025December 2025 highlights for metabrainz/listenbrainz-server: Implemented authenticated access enforcement for lb-radio/metadata APIs to prevent abuse by automated scrapers. The server now requires an authentication header and propagates user tokens for metadata lookups, with frontend components updated to verify user authentication before API calls. This security-focused change aligns with our access-control strategy and improves data protection for sensitive endpoints.
