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

* 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

* 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 "produced output that could not be read" persisting forever - the engine's JSON bugs were fixed engine-side long ago, but an already-installed engine was never updated; SE now detects outdated engine builds and offers the update - thx ProFire

* Live spell check: fix the English dictionary being used for other languages - thx muaz978
* Subtitle grid: fix an arrow key after shift+arrow jumping back to the anchor line instead of continuing from the moving end of the selection
* Undo: fix automatic change detection reading the subtitles from a timer thread, which could silently drop an undo entry or record a state that never existed
* Scroll bar: shift+click on the trough jumps to that position - thx muaz978
* Shortcuts: normal weight for the shortcut name column - thx muaz978
* Sync: add "Visual sync" to the subtitle grid context menu under "Selected lines", so segments that are off by different amounts can be synced one at a time - thx Hikari2w2
* OCR: "Save as" for an OCR'd subtitle opens in the source file's folder again, instead of e.g. Documents or the last-used folder - thx Turcote/fraternl

-----------------------------------------------------------------------------------------------------

v5.0.0 (22nd June 2026)

  Subtitle Edit 5 is a major new release and a big step for the project. 
  For the first time, Subtitle Edit runs natively on Windows, macOS, and Linux
  from a single, modern, cross-platform codebase. 
  The builds are self-contained, so no separate .NET installation is required, 
  and on macOS and Linux the needed media components (mpv/ffmpeg) are bundled in.
 
  Please read before upgrading:
 
  Subtitle Edit 5 is a new application, not just an update of Subtitle Edit 4.
  It has been rebuilt from the ground up to be cross-platform, so:
 
  - It is not 100% the same app. The look, layout, and some workflows have
    changed. Some things are in different places, and a few behave differently
    than in SE4.
  - Not every SE4 feature exists in SE5 yet. SE5 covers all the core editing,
    conversion, sync, video playback, OCR, and online services, but some of the
    more specialized SE4 tools are not available yet. Features will continue to
    be added.
 
  If you rely on a specific SE4 feature that is missing, please keep SE4
  installed alongside SE5. The easiest way to run both side by side is to use
  the Portable versions of SE4 and SE5, which keep their settings separate and
  do not interfere with each other.
 
  Which version should I use?
   
  - Subtitle Edit 5: recommended for most users on Windows 10 (22H2) or newer,
    macOS 12+, and Linux.
  - Subtitle Edit 4: please continue to use SE4 if you are on an older Windows
    version (Windows 7/8), or on older / slower computers where SE5 may not run well. 
    SE4 remains available and is the right choice in those cases.
 
  To run SE4 and SE5 at the same time, use the Portable versions - you can try
  SE5 while keeping SE4 as a fallback.
 
  Feedback is welcome on the issue tracker - it directly helps prioritize what
  comes next. Thank you to everyone who has supported and contributed to
  Subtitle Edit over the years :)
