 ## Highlights
 ### Added
 
-- Library Merge & Reassignment
-  - Duplicate library cards for the same show can be combined: select entries in "Select" mode and use "Merge Selected" to combine their sessions, mined cards, and watch time onto one card.
-  - Episodes can be moved to a different entry with a per-episode "→" button, fixing stray files that split off their own entry; manual assignments now survive later filename parsing, Jellyfin refreshes, and season repair.
-  - Exact AniList matches with compatible seasons merge automatically, while likely (fuzzy) matches surface as a dismissible "Possible duplicate" suggestion instead of merging silently.
+- **Japanese Subtitle Generation**:
+  - Generate Japanese subtitles locally with whisper.cpp, right from a modal (`Ctrl+Shift+G`), the subtitle sidebar's generation button when no subtitles are loaded, or `subminer generate-subs`, with progress, cancellation, and automatic loading into mpv when it's done.
+  - Pick and download an official multilingual Whisper model in-app (including smaller quantized variants), or point Settings at one you already have. SubMiner recommends `large-v3-turbo` when CUDA is available and `small` otherwise, and tells you up front if `whisper-cli`, `ffmpeg`, or `ffprobe` can't be found.
+  - An optional "Focus on spoken dialogue" mode uses a Silero VAD model to keep quiet or music-covered dialogue that would otherwise get dropped.
+  - Long passages split near natural speech pauses, guided by an existing subtitle track when one is loaded, giving tighter timing and fewer repeated-word glitches.
 
-- Duplicate Line Cleanup
-  - The Vocabulary tab's new **Duplicates** button scans a chosen time window for the repeated-line bursts described under Fixed below and collapses each burst to a single line once confirmed.
-  - A matching `subminer stats cleanup --duplicate-lines` command (with `--dry-run` and `--lookback-days <n>`) is available from the terminal.
-  - Only the affected subtitle lines and the vocabulary counts they inflated are touched; watch time and lines-seen totals are left as recorded.
+- **Media Timing Review Frame Picker**:
+  - The screenshot used for a mined card can now be chosen independently of the audio clip, with its own live preview, time slider, and frame-by-frame stepping.
+  - Works for local video and for seekable remote streams like Jellyfin.
+
+- **Overlay Keybinding Pickup**: The overlay now recognizes your mpv keybindings (from mpv's defaults, `input.conf`, and loaded scripts) as long as they don't conflict with SubMiner's own controls. Picked-up bindings work for the session but won't show up in the help menu.
+
+- **Subtitle Sidebar Selection & Copy**: You can now select dialogue across multiple subtitle sidebar rows and copy it, without timestamps, using Ctrl/Cmd+C or the Copy button, without seeking or mining a card.
+
+- **Jimaku Live Action Search**: The Jimaku modal has separate Anime and Live Action tabs (switch with Arrow Left/Right) so you can search Jimaku's live-action subtitle catalogue directly.
+
+- **Live-Action TMDB Library**:
+  - Live-action dramas and movies in the stats Library now get posters, synopses, and titles from TMDB.
+  - Titles AniList can't match are looked up on TMDB automatically when the parsed filename matches a title exactly; otherwise use the new **Link to TMDB** action. Entries linked to the same TMDB title merge into one card, and the Library kind selector gained a Live Action option.
+  - Release builds already include a TMDB key; if you run from source, set `tmdb.apiKey` (or `tmdb.apiKeyCommand`) yourself.
+
+- **YouTube Library Kind**:
+  - YouTube channels are now their own Library media kind, with new All Titles, Anime, and YouTube filters. Existing channel entries migrate automatically with viewing history and manual video assignments intact.
+  - Channels stay out of AniList matching, season repair, and duplicate recommendations, and can't be merged or moved into an anime entry.
+
+### Changed
+
+- **Bundled Bun Runtime**: Every SubMiner launcher, installed or downloaded, now runs on the Bun runtime bundled with the app instead of a system-wide Bun install. Recognized legacy launchers migrate automatically, Windows users get a new `subminer.cmd` download, and first-run setup now shows a single optional launcher control with runtime repair guidance only when something actually needs it.
+
+- **Compressed Incremental Sync**: Cross-machine sync between compatible macOS/Linux machines now transfers only what changed, compressed, using a cached snapshot from the last sync to cut traffic further. Machines without a compatible rsync (including Windows) fall back to compressed scp automatically, older peers keep working, and transfers now time out after 30 minutes instead of hanging indefinitely.
+
+- **Smaller Install Size**: Installers and the unpacked app are smaller after dropping demo media, source maps, TypeScript sources, test fixtures, and unused binaries, and sharing one Japanese UI font across windows. Release builds now publish a package-size comparison against the previous release.
+
+- **Stats Server Request Safety**: The stats server, including the in-app stats overlay which now loads through it, only accepts requests from the local machine and requires a JSON content type for anything that changes data. If you were exposing the dashboard through a reverse proxy or Tailscale Serve, that's no longer supported, and any script posting to the stats API needs to send `Content-Type: application/json`.
+
+- **Yomitan Updated**: Bundled Yomitan is updated to upstream 26.9.8, adding historical Japanese kana transformations and Ukrainian language support, plus improvements to Anki duplicate search and audio retrieval.
 
 ### Fixed
 
-- Subtitle Duplication from Karaoke & Animated Signs
-  - Typeset ASS karaoke and animated signs no longer flood the overlay, subtitle sidebar, immersion history, mined cards, or stats with repeated glyph fragments or per-frame duplicates; the complete authored line is recovered instead, without merging genuinely repeated dialogue or separately positioned signs.
-  - Fragmented karaoke now preserves the spaces the author placed between words instead of joining them together, and lyric transitions (including seeking into the middle of a line) resolve to the clean line instead of a stray entrance or exit frame.
-  - The secondary overlay shares the same deduplication logic as the primary overlay, including collapsing lines that differ only by whitespace or trailing punctuation, and sidebar navigation moves between clean lyric lines while keeping the right line selected.
+- **Jellyfin**:
+  - Playback, subtitles, artwork, and remote control now authenticate with an `ApiKey` parameter instead of legacy headers, so Jellyfin 12 works correctly even with legacy authorization disabled.
+  - "Play on SubMiner" no longer silently drops the connection after about a minute on Jellyfin 12.
+  - The "now playing" bar clears when you close or finish a cast video instead of running to the end of the episode.
+  - Anki cards mined from Jellyfin now get the real episode title in the misc info field instead of "Unknown media".
+  - Jellyfin streams no longer leak URL-derived titles or credential-bearing URLs into metadata, Anki fields, Discord presence, stats, or AniList lookups; previously cached data that had credentials in it is cleaned up automatically.
 
-- Anki Media Generation
-  - Sentence-audio generation no longer times out on slow network-mounted video files with many subtitle and font streams, and a failed extraction now reports a clear error instead of a raw `ENOENT`.
-  - Mined audio and animated AVIF clips now capture the subtitle line you actually mined, instead of whatever line happened to be on screen once slow audio extraction finished.
+- **Anki & Mining**:
+  - Word audio now reads from its own configured field (`ankiConnect.fields.wordAudio`) instead of the sentence-audio field, fixing animated word images that started moving immediately instead of on demand.
+  - Setting `ankiConnect.media.maxMediaDuration` to `0` for unlimited duration now also applies when mining from the stats dashboard, matching overlay mining.
+  - Closing the overlay while a media timing review is still loading now properly cancels setup, restores playback if the review had paused it, and cleans up the hidden preview player.
 
-- Character Dictionary Performance & Notifications
-  - Character dictionary generation, merged rebuilds, and imports no longer freeze the app on large dictionaries, and cached results (including character portraits) are reused across launches instead of regenerating everything every time.
-  - Portraits also now display correctly if their cache finishes loading after subtitles have already started showing.
-  - Desktop progress notifications, including on Linux AppImage installs, now update in place instead of flickering closed and reopening.
+- **Settings**:
+  - AnkiConnect, Kiku, and Senren settings are now validated before use, with a warning and a safe default for anything invalid instead of a bad value reaching runtime.
+  - Settings marked as applying live now correctly avoid showing a restart warning, and mixed saves apply the live parts immediately while listing only the sections that actually need a restart.
 
-- Overlay Reliability
-  - Overlay modals (settings, stats, etc.) now open promptly on the first shortcut press, including on repeated sessions on Windows, and appear above fullscreen mpv on macOS instead of switching Spaces or opening off-screen.
-  - The macOS window-tracking helper is now built for macOS 12.0+, so the overlay attaches to mpv on older systems like Ventura instead of crashing and getting stuck on "Overlay loading."
-  - The overlay no longer gets stuck on "Overlay loading" indefinitely if mpv's connection stalls; it now retries and shows an actionable error after 30 seconds.
-  - Fixed native Wayland drag-and-drop from file managers like Thunar, and fixed system-wide mouse lag on Windows caused by the overlay's click-through handling.
+- **Overlay**:
+  - Clicking a subtitle sidebar cue no longer leaves Space bound to seeking back to it; Enter still seeks the focused cue, and Space keeps whatever playback action you've configured.
+  - Hyprland recovery dialogs now stay above SubMiner windows instead of being covered by overlay placement updates.
+  - Fixed a rare case on Linux where a delayed window-close callback could reopen the overlay after it was torn down.
 
-- Stats Dashboard
-  - Deletes, library merges, video moves, and AniList reassignments no longer freeze the stats dashboard or rebuild lifetime totals from scratch; large deletes that used to take minutes now finish in milliseconds.
-  - Vocabulary totals and charts now count all tracked vocabulary instead of just the first page, and new-word history uses corrected daily rollups.
-  - Calendar labels respect time zones west of UTC, and vocabulary cards refresh automatically after editing the word exclusion list (with a Retry option if a load fails).
+- **Stats**:
+  - Malformed or partly invalid resource IDs are now rejected before they can affect library mutations or cover-art backfills.
+  - Stats server port conflicts now surface as a status notification instead of crashing SubMiner, and startup/shutdown are more robust: concurrent startup requests share one attempt, stopping a background instance no longer disconnects an open dashboard, and shutdown no longer waits indefinitely on active requests.
 
-- Linux Launcher Thumbnails
-  - Fixed missing MKV thumbnails in the Linux rofi picker when the system thumbnailer only registers legacy Matroska MIME aliases.
+- **Subtitle Sidebar Gap Follow**: The subtitle sidebar now stays near actual playback position during gaps in files where a cue starts at time zero.
+
+- **First Launch on macOS**: Fixed first launch exiting immediately when the SubMiner config directory didn't exist yet.
