v5.1.0-rc10 (20th of July 2026)

* New "file saved" prompt - success check mark, file name and folder, size/duration info, copy path and Play/Open - now also used by text to speech and the video tools (burn-in, cut, re-encode, transparent subtitles, blank video, embedded subtitles)
* Auto-translate via llama.cpp: add Hy-MT2 translation models (Tencent, 7B/1.8B - excellent for its 33 languages, no Nordic) plus larger TranslateGemma 12B and Qwen 3.5 9B quants (up to 10 GB)
* Auto-translate: the URL field was ignored for winstxnhdw/nllb-api, NLLB-serve, Anthropic, Groq, OpenRouter and Nvidia - and nllb-api now tolerates a missing trailing slash in the URL - thx 3ftomi
* Text to speech: fix the voice-clone transcript prompt appearing repeatedly and generation using a different voice than picked (MOSS-TTS and sibling clone engines)
* Speech to text: live progress (and time remaining) for all CrispASR engines
* Update CrispASR to v0.8.15
* Fix Ctrl+F/Ctrl+H (and all other shortcuts) not responding after closing a dialog such as spell check, until clicking inside the window - thx fraternl
* Multiple replace: fix regex rules corrupting ASSA \N line breaks on Windows - also covered Batch Convert's replace step and regex Find & Replace - thx Davanix
* Burn-in: more compact settings so the window fits smaller screens, and audio settings tidied up
* Remember window position/size for fix-list tool windows
* Performance: much faster subtitle grid rendering (live spell check, CPS/WPM columns) and faster ASSA file loading
* Performance: core-library micro-optimizations - thx ivandrofly
* Update Japanese translation - thx hisui3393
* Update Italian translation - thx bovirus
* Update Polish translation - thx potplayer-fanpack

v5.1.0-rc9 (19th of July 2026)

* Text to speech: add MOSS-TTS (CrispASR) engine with zero-shot voice cloning
* OCR: new "Show only forced subtitles" filter and a Forced column - only the forced lines are OCR'ed and returned, like SE4 - thx heniowise
* OCR: fix forced-filter edge cases - hidden lines now receive pre-processing/palette changes, deleting a visible line no longer wipes hidden lines' unknown words, delete is blocked while OCR runs, and the VobSub color chooser previews the correct image
* Multiple replace: fix phantom empty line (and stray red mark) in the preview's Before column with regex rules on Windows - thx Davanix
* Text to speech: harden the window's close path and add diagnostics for a reported crash when closing with OK - thx cvrle77
* Text to speech: an audio playback failure in the review window no longer leaves all play/regenerate buttons dead
* Speech to text: update CrispASR runtime to v0.8.13 - the linux-arm64 build is also back
* Speech to text: single-mode transcribe no longer picks up a leftover queued file - and no longer wipes the batch queue
* Auto-translate: fix languages with underscores in the engine name never matching (e.g. Google Translate V1 Chinese) and the dialog getting stuck on "Translating..."
* Embedded subtitles (mkv): the dialog no longer locks up after a failed generate
* Burn-in/transparent video: cutting now burns the correct lines, keeps ASSA styles/header, and includes lines straddling the cut boundary
* Batch convert: "Open containing folder" now opens the file's folder on Windows when the path contains spaces - thx cyberbrix
* Fix parser edge cases: SAMI crash on malformed files (broke format auto-detection), WebVTT cues with mixed short/long timestamps being dropped, TTML fractional seconds, MicroDVD lines with two empty time codes
* SeConv: auto-detect the subtitle language for MP4/MKV container tracks with no declared language (or "und") - thx ivandrofly
* Update Chinese Traditional translation - thx love80312
* Update Russian translation - thx jekovcar
* Update Bulgarian translation - thx jekovcar
* Update Polish translation and interjections - thx potplayer-fanpack
* Update Turkish translation - thx bilimiyorum

v5.1.0-rc8 (18th of July 2026)

* Waveform: add SE4-style Previous/Play/Pause/Next text buttons to the waveform toolbar
* Subtitle text box: disable ligatures - letter pairs like "fi" no longer merge into one glyph, so the caret and mouse selection treat each character separately - thx subcor
* Subtitle text box: roll back rc7's right-to-left ASSA tag rendering fix - clicking inside a tag in a right-to-left line could crash; the misplaced backslash is cosmetic only and the fix will return once Avalonia can render it safely - thx muaz978
* ASSA: fix missing closing tag when setting font name on selected text - thx rRobis
* Fix common errors: "Fix invalid italic tags" no longer eats the character before a dangling begin tag and now repairs more two-line stray-tag shapes
* Cavena 890: fix Chinese write path so text and italics round-trip
* Fix six silent text-corruption edge cases (nested closing tags, UTF-16 detection, "Fix uppercase 'i' inside words", Turkish casing after colon, Cavena 890 Hebrew italics, DVD Studio Pro bold+italic) - thx ivandrofly
* Harden the binary subtitle parsers against malformed files (crashes, out-of-memory, infinite loops) - thx ivandrofly
* Fix image edge cases in transparent-image detection and rectangle copying - thx ivandrofly
* Network: fix proxy password decoding, a crash when no proxy is configured, and auto-translate request issues - thx ivandrofly
* Performance: three core-library micro-optimizations
* SeConv: malformed Scenarist SCC input no longer converts "successfully" to corrupt output - files where nothing can be decoded now fail with a clear error and a non-zero exit code, and partially damaged files convert with a warning (console and --json) - thx lthibault-stingray
* Update Korean translation - thx 12si27
* Update Italian translation - thx bovirus

v5.1.0-rc7 (17th of July 2026)

* Subtitle grid: "Insert subtitle after current line..." now works on any line, not only the last - and the inserted file keeps its own time codes like SE4 (only shifted when it would overlap the selected line), so pre-timed subtitles land at their real positions - thx UUMARTIN
* Waveform: "Insert subtitle file at video position..." is now available anywhere on the timeline (was only past the last subtitle) - inserts at the right-clicked position and warns before creating overlapping lines - thx UUMARTIN
* Speech to text: the input language is remembered again like SE4 - restored on window open, kept when changing engine/settings, and no longer overridden by auto detection in "Selected lines - Speech to text" - thx UUMARTIN
* Subtitle text box: restore live spell check with "Color tags" enabled - red underlines and the context menu suggestions/add to dictionary/ignore all work again in the new syntax highlighting text box
* Subtitle text box: fix ASSA override tags rendering with a misplaced backslash in right-to-left lines - "{\an8}" showed as "{an8\}" - thx muaz978
* Update Polish translation and add Polish names list - thx potplayer-fanpack

v5.1.0-rc6 (17th of July 2026)

* Waveform: new option "Center video position also while paused" (Settings - Waveform/spectrogram) - restores SE4's center/lock mode: with "Mouse-wheel sets video position" on, scrubbing keeps the cursor centered so the waveform scrolls as one continuous strip, and "select current subtitle" also applies while scrubbing paused - thx Asztec00
* Open video from URL: the "Download yt-dlp" button is now only shown when an update is actually available - it was always visible, even with the latest yt-dlp installed
* Open video from URL: add "Save..." button to the "Pick subtitle to download" window - saves the selected downloaded subtitle file as-is to a location of your choice
* MP4 track picker: the "Export..." button now works - text tracks save as SubRip, VobSub image tracks export to Blu-ray .sup

v5.1.0-rc5 (17th of July 2026)

* Subtitle text box: tag coloring (HTML/ASSA) now uses a new native text box - same colors as before, but centering, IME/CJK input, right-to-left and the context menu work exactly like the normal text box, and toggling right-to-left no longer turns off tag coloring
* Subtitle text box: fix crash while typing an unterminated attribute quote (e.g. <font color=") with tag coloring enabled
* Source view: add context menu to the text editor - thx pdjdev
* Point sync via other subtitle: sync points are now chronologically sorted, and setting a point on a line that already has one re-points it instead of adding a duplicate - thx fraternl
* Point sync via other subtitle: fix deleting a sync point - the context menu now shows Delete (and Delete/Backspace on the list works) instead of silently removing the point on right-click - thx fraternl
* Point sync via other subtitle: clicking a line in the left list scrolls the other subtitle's list to the matching time (selection is left untouched) - thx fraternl
* Point sync via other subtitle: icon on the "Set sync point" button
* Point sync via other subtitle: a long "other subtitle" file name no longer pushes under the "Find text" button - it now shrinks with an ellipsis
* Point sync: sync points are now chronologically sorted, and setting a point on a line that already has one re-points it instead of adding a duplicate
* Point sync: fix deleting a sync point - the context menu now shows Delete (and Delete/Backspace on the list works) instead of silently removing the point on right-click
* Point sync: icon on the "Set sync point" button
* Performance: faster time code display in HH:MM:SS:FF mode, faster ASSA/SSA file loading, and allocation-free URL checks
* Performance: faster "Fix missing spaces", time code parsing and extra-space cleanup in the core library
* Time code spinner: mouse click/wheel now nudges 100 ms (one frame in frame mode) instead of stepping the caret's segment - the caret defaults to hours, so a click jumped a whole hour - thx muaz978/AdiOpi
* Speech to text (Qwen3 ASR CPP): fix...
