Jellyfin Server 10.11.6 is a bugfix-focused stable release that improves search relevance, metadata handling (artists/people, ratings, images), library monitoring, and playlist/Continue Watching behavior. It also tightens media format checks and fixes several playback/transcoding edge cases (HLS fallbacks, Dolby Vision tags, HWA handling) plus a crash with invalid plugin repo URLs. Users and integrators should see more reliable library updates and metadata consistency, fewer playback issues, and improved stability after upgrading.

Jellyfin Server 10.11.5 is a minor bugfix release focused on stability, performance, and media handling. It fixes issues like database query inefficiencies, metadata and image handling (backdrops/trickplay), scan and crash regressions (including .ts stream fallback and stack overflow during scan), and hardware-specific AV1/trickplay problems on RK3588/RK3576, plus assorted filtering and matching edge cases. Users and integrators should see fewer crashes/hangs and more reliable library/metadata behavior, with no major feature changes.

Jellyfin Server 10.11.4 is a bugfix-focused stable release that improves reliability and performance across scanning, filtering, and API behavior. It fixes crashes and exceptions (including exFAT ResolveLinkTarget and path comparison NREs), addresses database save/order issues to avoid foreign-key errors, improves locked-field saving and movie filtering, and adds safer media handling like avoiding HDR-to-SDR copy and limiting first-frame probing to file sources. Users and integrators should see fewer library and metadata issues plus faster OpenAPI generation, with no major feature changes.

Jellyfin Server 10.11.3 is a minor bugfix release that improves library scanning/metadata handling (NFO/TMDB ID detection, season parsing, series/playlist date fields), ignore file behavior (including Windows), search/sort and collection grouping, plus several stability fixes for edge-case errors. It should make upgrades smoother and libraries more accurate for users, while integrators may note small behavior changes like updated tag filtering logic and a new configurable SQLite timeout.

Jellyfin Server 10.11.2 is a minor bugfix and security release that tightens password reset behavior and fixes several stability/metadata issues (legacy migrations, file size updates on metadata refresh, season number parsing, optimistic locking, and audio-only container timing). This improves reliability and consistency for admins and integrators, with minimal functional change for end users beyond smoother library refreshes and playback edge cases.

Jellyfin Server 10.11.1 is a minor, bugfix-focused release that improves library and filesystem handling (symlinks, path normalization, folder sorting/pagination), makes backups/migrations more resilient (skipping invalid entries and cache data, faster trickplay migration), and tightens playback/transcoding behavior (chapter saving within runtime, better HDR10+/HDR compatibility checks). For users this should mean fewer upgrade/migration hiccups and more reliable media browsing and playback; integrators/plugin authors benefit from more robust metadata ID checks, plugin filtering by ID, and a small dependency update.

Jellyfin Server 10.11.0 is a major feature + bugfix release with big operational improvements like full system backups, .gitignore-style library ignoring, startup/storage health checks and UI status overlays, plus a large refactor of the media database to EF Core (library.db → jellyfin.db). It also removes automatic port forwarding and delivers many performance, metadata/library scanning, API, migration, and hardware transcoding/subtitle rendering fixes—integrators should review the important upgrade notes, as the database/migration and API behavior changes can affect plugins and deployments.

Jellyfin Server 10.11.0 RC9 is a preview update focused on polishing and stability, with fixes for ratings, sorting (including box sets and grouped counts), library/collections issues, NFO/user-data saving, and an audio LUFS deadlock, plus performance improvements to people and music-artist queries.

Jellyfin Server 10.11.0 RC8 is a preview release focused on a critical bug fix: it corrects a migration issue that could break libraries (and in some cases delete items) when upgrading from RC5 or earlier to RC7, so RC7 should be avoided. It also tweaks build behavior by limiting custom code analysis to debug builds and adds an explicit reference check to the migration. This is primarily a bug-fix release with minor developer/build improvements, and users/integrators on RCs should upgrade to RC8 to ensure safe upgrades and prevent library damage.

Jellyfin Server 10.11.0 RC7 is a preview update focused mainly on fixes and stability: it rolls back to the last working SkiaSharp version, corrects several database/metadata issues (people deduplication, foreign keys for unconnected items, NFO/import ordering), and adds small API/build improvements like exposing subtitle extraction and expanding ABI diff coverage. For users and integrators this should mean fewer regressions and more reliable library/people metadata handling, but as an RC you should upgrade for testing only and plan to rescan libraries and run a PeopleRefresh after updating. Overall this is primarily a bug-fix release with a couple of minor feature/exposure changes.

Jellyfin Server 10.11.0 RC6 is a preview update focused on bug fixes, performance/stability tweaks, and dependency/CI upgrades. It improves library/metadata behavior (e.g., anamorphic detection, 3D format preservation, people/album-artist/collection handling, IsPlayed filtering), reduces system impact by running background ffmpeg tasks at lower priority, and includes more robust migrations/DB handling and error logging. Testers and integrators should expect smoother upgrades from earlier RCs but should rescan libraries and run PeopleRefresh after updating; packages are available via manual downloads or Docker preview/rc6 tags (not apt/latest).

Jellyfin Server 10.11.0 RC5 is a preview update focused on stability and performance: it refactors some database/API queries to avoid timeouts on large libraries, fixes related-item count calculations and a few filtering issues, and tweaks image saving behavior, plus routine dependency/CI updates and a small locale code correction. Impact is mainly smoother browsing and fewer API slowdowns for big installations, with no major new end-user features in this RC. Overall this is primarily a bug-fix and performance polish release candidate for testers and integrators ahead of 10.11.0 final.

Jellyfin Server 10.11.0 RC4 is a preview build that adds VOB file support and includes a broad set of fixes and refinements around database/migrations, backup & restore, library refresh/cleanup, trickplay extraction, recordings visibility, and media/metadata handling (plus dependency updates). The impact is a more stable and compatible 10.11.0 candidate—especially for upgrades and restores—while integrators and testers should validate database/backup workflows and note improved request/session handling and new progress reporting for audio normalization. Overall, it’s both a feature update (notably VOB support) and a bugfix/stability release.

Jellyfin Server 10.11.0 RC3 is a preview update focused on polish and stability since RC2, with fixes for startup logging/health checks, SyncPlay group playback, music metadata and album stacking options, collage generation, and several playback/transcoding improvements (notably QSV on Windows and VAAPI gating).
