December 2025 highlights: Delivered a sweeping Compose-based UI migration for Jellyfin Android TV settings and related surfaces (Telemetry, Developer, Licenses, server/user, and home/library/live TV guide), enabling unified UX and faster iteration. Implemented Settings navigation and initial parameter support in the router, with ProvideRouter improvements for defaultRouteParameters. Modernized the design system with tokens and new UI primitives (SettingsColumn, RangeControl, ListControl base, ProfilePicture) to accelerate feature delivery and ensure consistency. Expanded media capabilities (FMP4 transcoding, AAC-over-HLS for music) and AboutLibraries integration, plus build/readme improvements and CI workflow enhancements. Improved reliability and quality with better error rendering (ListMessage), preventing seeking when duration is unknown, and removal of deprecated preferences.
