penshot-qt Changelog (Version: 3.5.1):
ad3cb29 2026-04-05 Jonathan Thomas Fixing some Codacy nitpicks in our unit tests mostly. HEAD, origin/release-20260402
70c4613 2026-04-05 Jonathan Thomas Translating "User Interface Scale" in UI and documentation
c8fd103 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)
2d1d99f 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.
0fdd954 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.
ff1362d 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)
38188a0 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.
61620a0 2026-04-03 Jonathan Thomas Updating supporters.json file with credits from donations.
7211faa 2026-04-03 Jonathan Thomas Fixing a regressio

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.
