Highlights & Features:

• Upgraded Razor tool with source-frame previews, snapping, removal shading, and ripple cuts that close gaps on the same track.
• Improved timeline navigation with persistent clip titles and effect controls, clearer zoom-slider handles, and more consistent thumbnails.
• Faster color and keyframe editing, more responsive trim previews, and smoother live transform adjustments.
• Fixed macOS startup failures caused by missing library dependencies on systems without Homebrew.
• Improved stability, undo/redo history, project saving, asset handling, and compatibility with older project layouts.
• Restored native file dialogs and improved Inkscape and Blender workflows, including access for editors installed as Snaps.
• Added non-interrupting announcement banners. Dismissed update notices stay hidden until the next release.
• Introduced official Linux Snap support with automatic updates and desktop menu integration.
• Improved recording workflows, Linux webcam discovery, and Windows recording-file handling.

• 25a2655 2026-04-16 geekrebel Replacing the hard-coded /usr/local/Cellar/python@3.7/3.7.9_2/... PATH in installer/build-mac-dmg.sh with Homebrew-prefix detection, so the script runs on both Apple Silicon (/opt/homebrew) and Intel (/usr/local) Macs.
• adb4131 2026-04-16 geekrebel Making the macOS DMG filename arch-aware so builds on Apple Silicon produce OpenShot--arm64.dmg while Intel Mac builds continue to produce OpenShot--x86_64.dmg. Arch is detected via platform.machine(); any non-arm64 value (including Rosetta-translated Python on Apple Silicon) keeps the existing x86_64 suffix, so Intel Mac build pipelines are byte-identical.
