Full Release Notes

# HyperFrames v0.7.68

Released on 2026-07-22.

Bug-fix release. The video coverage gate no longer aborts renders of looping short videos, and composition-level CSS with native CSS Nesting now applies to nested selectors instead of being silently ignored.

## Fixes

- **Producer:** Credit looping short videos in coverage gate (#2665). A short clip in a longer slot with `loop` set delivers all its source frames once and reuses them per repeat; the gate now measures against source-source instead of unique-source-vs-slot, so a 3s looping clip in a 10s slot no longer aborts at 30% coverage ([a637f394e](https://github.com/heygen-com/hyperframes/commit/a637f394ee900c64c8f2e1ee78cf1e0ce17b8739), [#2732](https://github.com/heygen-com/hyperframes/pull/2732))
- **Core:** Preserve nested-rule selectors in composition CSS scoping (#2721). Native CSS Nesting (Chrome 112+ / Firefox 117+ / Safari 16.5+) now works inside a composition's `<style>` block; the scoper no longer re-applies the composition selector to nested rules, so `[data-composition-id="foo"] { .title { … } }` correctly matches `.title` inside the composition ([1e2c7d673](https://github.com/heygen-com/hyperframes/commit/1e2c7d673fc0fe8da9a822bb7a8744f84f44d9d4), [#2733](https://github.com/heygen-com/hyperframes/pull/2733))
