These include a fix for Multitrack Video setting the Maximum Video Tracks to 10 if set to "Auto", a fix for Browser Source hardware acceleration failing in the Flatpak version, and a fix for incorrect progress bars and spacing around scrollbars. Additionally, the fix addresses a freeze on Linux when using PipeWire capture with explicit sync.
