+Grouped audio now stays consistent from Studio preview through export, with safer edits, carve analysis, and validation. This release also removes the unfinished solo and group meter controls.
+
+## Breaking Changes
+
+- **Studio:** Remove the session-only “Hear only this” control and live group meter. Existing compositions need no migration because neither wrote project data ([05affaae2](https://github.com/heygen-com/hyperframes/commit/05affaae2175a6dde0e2eafa5e702b67863d721c), [#3454](https://github.com/heygen-com/hyperframes/pull/3454)).
+- **Core:** Remove `window.__hf.setAudioSolo`. Custom Studio integrations must stop calling this preview bridge ([05affaae2](https://github.com/heygen-com/hyperframes/commit/05affaae2175a6dde0e2eafa5e702b67863d721c), [#3454](https://github.com/heygen-com/hyperframes/pull/3454)).
+
+## Features
+
+- **Lint:** Report invalid group timing, misplaced carve settings, and membership problems without rejecting valid cross-file groups ([54091b501](https://github.com/heygen-com/hyperframes/commit/54091b5015aa0d45ca61275e75567701daf6e2b2), [#3447](https://github.com/heygen-com/hyperframes/pull/3447)).
+
+## Fixes
+
+- **Core, Engine:** Keep group identity, mute state, gain, automation, and FX routing consistent across inlined previews and FFmpeg exports ([#3444](https://github.com/heygen-com/hyperframes/pull/3444), [#3445](https://github.com/heygen-com/hyperframes/pull/3445), [#3446](https://github.com/heygen-com/hyperframes/pull/3446)).
+- **Engine:** Preserve bus headroom and clean temporary files when grouped mixes fail. Render errors now retain structured context ([1aec3b4a0](https://github.com/heygen-com/hyperframes/commit/1aec3b4a09ea99e35b8d082b329fd3152d088e78), [#3446](https://github.com/heygen-com/hyperframes/pull/3446)).
+- **Studio:** Apply group creation and edits as one transaction across source files, live DOM state, undo, and expanded sub-compositions ([#3448](https://github.com/heygen-com/hyperframes/pull/3448), [#3449](https://github.com/heygen-com/hyperframes/pull/3449)).
+- **Studio:** Keep preview hydration, selection, reveal requests, group state, and property-panel controls synchronized through HMR and remounts ([#3450](https://github.com/heygen-com/hyperframes/pull/3450), [#3453](https://github.com/heygen-com/hyperframes/pull/3453)).
+- **Studio:** Prevent self-carve, reciprocal carve, and duplicate analysis. Repeated FX reveal requests now reopen the intended control ([f575bdadc](https://github.com/heygen-com/hyperframes/commit/f575bdadcbc9461df038a9fa84092ba22da9b18a), [#3452](https://github.com/heygen-com/hyperframes/pull/3452)).
+- **Studio:** Align group rows, track headers, and automation lanes. Audition starts where selected audio is actually playing ([4ea018a4a](https://github.com/heygen-com/hyperframes/commit/4ea018a4a7ccdfee4e77538c336c37d366876779), [#3451](https://github.com/heygen-com/hyperframes/pull/3451)).
+
+## Docs & Examples
+
+- **Audio:** Document submix buses, group attributes, routing rules, and carve guardrails in the HyperFrames skills and contributor guidance ([2685c8f22](https://github.com/heygen-com/hyperframes/commit/2685c8f2231e39da31871f25b2e4609551a78c76), [#3455](https://github.com/heygen-com/hyperframes/pull/3455)).
