The project list shows when subtitle replacement is complete and the video duration.

Image translation downloads returned the watermarked original instead of the translated image.
Broken timecodes in SRT/VTT downloads and an empty line inserted between two-line subtitles.
The video froze while a transcription job was running.
Inconsistent case handling in search and replace; bulk replace with an empty string is now disabled.
Data from the previous workspace remained visible after switching workspaces.
Project creation: the project name was ignored when uploading a folder, title numbering for multiple videos, the upload progress bar stuck at 10%, and missing source languages.
Added an error message when the progress history download fails, and fixed the “per sentence (subtitle)” value showing as Infinity.
Media Sales Kit: viewing time shown as NaN, a render loop on the analytics screen, and DRM playback recovery.
Squashed webtoon thumbnail rows, video metadata parsing, and the message shown when the asset upload quota is exceeded.
Project deletion is now reflected on screen only after the server confirms it.

4. Performance

5. Security
