openshot-qt Changelog (Version: 3.5.1)

• ad3cb296d 2026-04-05 Jonathan Thomas Fixing some Codacy nitpicks in our unit tests mostly. HEAD, origin/release-20260402
• 70c461390 2026-04-05 Jonathan Thomas Translating "User Interface Scale" in UI and documentation
• c8fd103b2 2026-04-05 Jonathan Thomas Adding User Interface Scale to preferences, to allow users to easily change the scale of OpenShot. When Enabling the Legacy Timeline it disables this option, and sets it back to 100% scale (our legacy web timeline backends have ugly artifacts when using some fractional scales)
• 2d1d99f45 2026-04-05 Jonathan Thomas Fixing SHIFT+Scroll Wheel regression, where our new qwidget timeline backend did not scroll horizontally when SHIFT was pressed. Added unit tests as well.
• 0fdd954aa 2026-04-05 Jonathan Thomas Align razor icon with mouse position hotspot in QCursor (qwidget timeline backend). It was offset incorrectly, so the dotted line was not aligned with the actual cursor position, thus cutting in the wrong place.
• ff1362dc9 2026-04-03 Jonathan Thomas Invalidate all qwidget timeline clip thumbnail caching when "Edit Title" is used, so thumbnails of titles stay in sync after edits (dragging thumbnail, initial timeline thumbnail, and dropped thumbnail)
• 38188a054 2026-04-03 Jonathan Thomas Updating file menu image used in docs, due to missing "Optimize" option in the menu. Updating README.md to add missing English PDF for website.

• 7211faa61 2026-04-03 Jonathan Thomas Fixing a regression which added Preview->Optimize to the main windows top menu - oops.
• bda95f5cf 2026-04-02 Jonathan Thomas Fixing many Codacy nitpicks and complaints. Mostly minor changes - I validated all the code still works and tests pass.
• 6d1a673ba 2026-04-02 Jonathan Thomas Adding final 3.5.1 translation compiled files (qm files)
• 7bfb2c11f 2026-04-02 Jonathan Thomas Adding missing translatable strings for Optimize feature

• 8758e80e2 2026-04-02 Jonathan Thomas Updating core OpenShot translation templates for new release
• de6d8aad1 2026-04-02 Jonathan Thomas Fixing regression on auto-play preview dialog (was slow to open, resize event was fighting auto-play signal), now it's faster to start playback, and still resizes correctly when window changes sizes.
• c81203559 2026-04-02 Jonathan Thomas Merge branch 'develop' into optimize-preview
• 7426b8634 2026-04-02 Jonathan Thomas Updating a few more user-guide images to have white backgrounds instead of black (for alpha)
• feac216fc 2026-04-02 Jonathan Thomas Updating a few more user-guide images to have white backgrounds instead of black (for alpha)
• 142ada717 2026-04-02 Jonathan Thomas - Updating all preferences images in user-guide to use white background, and updating preview tab image with new optimized video settings. - Refactoring asset moving code, to be sure we remove the assets as we move them (titles, optimized videos, protobuf files, thumbnails, etc...) - New Unit tests
• 55c7c2cdb 2026-04-01 Jonathan Thomas Fixing some Optimize issues found during testing: - Optimize on an unlinked file, just links it again - Delete & Unlink now works again (broke due to file path issues) - Fixed a backup_assets/ folder path issue, when a backup.osp is used (it just just resolve to the .openshot_qt/ folder. - Added a main window, Edit->Clear->Optimized Videos option (if optimized files exist)
• 79d32f378 2026-04-01 Jonathan Thomas Lots of improvements to optimize feature, renaming menu, updating docs, improving file name matching for "Link to Existing" to more closely match behavior of other common suffixes and established/expected patterns.

• 250254b27 2026-03-30 Jonathan Thomas Integrating new, faster thumbnailing, with a 3X thumbnail size max decode (so our Thumbnail function can still scale it down with higher accuracy - clearer picture)
• c419f7a93 2026-03-30 Jonathan Thomas Add to Timeline dialog now selects clips after adding them to the timeline - similar to dragging files directly onto the timeline (identical behavior now)
• 30e915170 2026-03-30 Jonathan Thomas Improving zooming on timeline (CTRL+Scroll Wheel, and CTRL+Press Scroll Wheel) to leave playhead at existing position, and center zoom around that position. Also fixing a small snapping regression.

• 415a40e7a 2026-03-30 Jonathan Thomas - Add new Proxy Service to manage a new "Optimize Preview" feature - Optimize Preview intercepts JSON to libopenshot, and substitutes lower resolution preview media, and manages this process (generating new low-resolution files, linking pre-existing low-resolution files, removing low resolution proxy files. - Moving thumbnails into folders per file id - New unit tests - New settings to manage "Optimize" process (in Preview tab on preferences)

• a271c9919 2026-03-27 Jonathan Thomas Preview the correct clip/transition when multiple clips are selected and being trimmed/re-timed. Which ever item initiated the trim, will be the one previewed.
• 68dc2c243 2026-03-27 Jonathan Thomas Improving transition resizing and retiming, to always show the static keyframes for brightness, and ensure they are still visible after resizing. Also, some cleanup work around this same feature.
• 9e10a86ba 2026-03-27 Jonathan Thomas Fixing multi-item trims/retiming to use the same exact position for all items, to prevent drift as updates are applied and mouse is still moving.
• e1c4e5239 2026-03-27 Jonathan Thomas Fixing first and last thumbnail slots (on Entire mode) to use center of slot as the frame #, instead of anchoring to the start/end frames - which was causing all sorts of issues. This is simpler, and consistent with how the other slots report their center frames.

openshot-qt Changelog (Version: 3.5.1)

• ad3cb296d 2026-04-05 Jonathan Thomas Fixing some Codacy nitpicks in our unit tests mostly. HEAD, origin/release-20260402
• 70c461390 2026-04-05 Jonathan Thomas Translating "User Interface Scale" in UI and documentation
• c8fd103b2 2026-04-05 Jonathan Thomas Adding User Interface Scale to preferences, to allow users to easily change the scale of OpenShot.

Highlights & Features:

• New default timeline: The new QWidget timeline is now the default, with much smoother zooming, scrolling, dragging, trimming, snapping, and multi-clip editing, especially on larger projects.
• New keyframe panel and major timeline polish: The keyframe panel is now part of the default editing experience, with smoother dragging, better selection behavior, improved snapping, high-DPI thumbnails, live trim feedback, and many workflow refinements.
• Smaller export file-sizes: Export presets were improved for smaller files and better quality, Blender GPU rendering is now enabled by default for Animated Titles, and hardware decoding checks are more reliable and user-friendly.
• Experimental ComfyUI integration for advanced AI workflows: OpenShot 3.5 adds a major first pass at ComfyUI integration, including generation workflows, tracking and segmentation tools, custom JSON workflows, progress reporting, and better remote-server handling.
• Improved stability, testing: This release includes expanded unit tests, new UI and replay-based testing tools, better missing-file dialogs, improved autosave and packaging reliability, smoother project loading, and a long list of bug fixes across the app.
