# HyperFrames v0.7.64

Released on 2026-07-18.

Studio editing is more predictable: multi-selection drags now keep composition positions in sync,
and Acorn-based atomic cuts stay isolated from Recast behind explicit operation-family gates.
Preview and render compilation now share a semantic-parity contract, while local `.scratch` files
no longer pollute lint runs.

## Fixes

- **Studio:** Keep composition multi-drag positions in sync ([f7911d10b](https://github.com/heygen-com/hyperframes/commit/f7911d10b0a7deac6fe4630947b53434d237ad21), [#2629](https://github.com/heygen-com/hyperframes/pull/2629))
