# HyperFrames v0.7.66

Released on 2026-07-21.

Studio preview audio now plays at playback speeds above 1x instead of being silently muted, and the mute control stays usable at every speed. This release also fixes an engine worker frame-stride false-positive and lands a c2v skills mining pass with new blueprints and rules.

## Features
