[0.8.1] - 2026-02-16

• Added a Mismatch Center drawer to compare provider-by-provider playback match outcomes (Tautulli/Plex/Jellystat when multiple history providers are configured), with filtering/grouping and CSV export backed by GET /api/mismatches.
• Resolved an issue where bitrate estimations were falling back to audio only totals, causing unexpectedly small bitrates estimations for some entries. Thanks, sorthe!
• Added Plex as a read-only playback provider (library scan + history ingestion) with cache-aware matching.
• Setup: Added Plex connection fields, section filters, and history page sizing.
• Added Plex diagnostics endpoint summary (sections, history stats, activities).
• Added provider-agnostic playback diagnostics endpoint (POST /api/diagnostics/playback-match) with shared match/health fields and provider-specific details for Tautulli/Plex.
• Added Plex media-source table fallback: when Sonarr/Radarr are not configured, /api/shows and /api/movies can populate from Plex library rows (with selected playback/history overlay).
• Added Plex Insights drawer (hubs, section filter, match health summary, activities, butler) with optional live updates.
• Fixed playback cache serialization when multiple users are present (user_ids now stored as a list).
• Fallback when Plex rejects the viewedAt history filter (retries without cutoff).
• Fixed Plex/Jellystat cache serialization for title-year index keys.
• Setup now supports multiple history providers at once (Tautulli, Jellystat, Plex) with an explicit preferred history source selector.
• Added preferred media source selector in setup for clearer provider delineation when multiple sources are configured.
• Playback provider selection now honors saved history source preference before falling back to auto-priority.
• Setup validation now supports Plex-only media configurations; Sonarr/Radarr are no longer required when Plex is the selected media source.
• Added backend provider option-set metadata (option_set) to /api/config for deterministic source/capability handling.
• UI tabs now use Shows/Movies labels while preserving Sonarr/Radarr internals.
• Added per-tab Plex library scoping (multi-select) with persisted UI selection.
• Plex library scope is now exposed in status/diagnostics payloads and response headers for clear in-scope visibility.
• Fixed status-row hidden state pointer interception that could block top action buttons.
• Standardized UI wording to Shows/Movies for load and refresh status text.
• Compacted health badges by default and added inline details expansion for long alerts.
• Simplified numeric cell rendering to improve table readability.
• Matching: kept ID-first and title+year-first order, then added guarded plain-title fallback (<=2-year drift when Plex year is known) to reduce Plex/*arr false negatives.
• Performance/UI: enabled Sonarr virtual row rendering for large lists and kept season expansion in-place (no forced full-table handoff) to reduce DOM/a11y snapshot pressure.
• UI: ensured Columns popout layers above status/progress regions (including fullscreen transitions), with stable header/status/chip loading placeholders.
• UI: consolidated Reset UI clearing so startup reset_ui and Reset UI button both clear filters/chips/query/view state consistently.
• Rendering: reduced reflow churn with read/write layout batching, per-render title/path measurement caching, and wrap-height recalculation memoization.
• Startup/perf: deferred non-critical chip/status bindings until first paint settles, lowered initial hydration pressure, coalesced status poll fetches, and added font preload/fallback metric stabilization.
