HyperFrames v0.8.7

Released on 2026-08-21.

Audio now works in groups. Set one volume, one mute, or one FX rack across many clips at once, and hear the same thing in preview that lands in the export.
Studio also got a broad UX pass across captions, the player, the panels, and the sidebar, and lint findings now show up inside Studio.
