+Studio now switches the canvas and timeline for compositions stored anywhere in a project. Snapshots now preserve playback rate, nested-media timing, static compositions, and source files.
+
+## Fixes
+
+- **Studio:** Switch the canvas and timeline for compositions stored outside `compositions/` ([adf9b0cce](https://github.com/heygen-com/hyperframes/commit/adf9b0cceeb561fd5424e8cad73b781f5383a9ef)).
+- **Core:** Keep long nested videos visible when their local start precedes the host window ([3dc185623](https://github.com/heygen-com/hyperframes/commit/3dc18562323c9dd7dfa1f9416d90708677f3652b), [#3535](https://github.com/heygen-com/hyperframes/pull/3535)).
+- **CLI:** Capture the correct source frame for trimmed or accelerated videos ([d99eeef0b](https://github.com/heygen-com/hyperframes/commit/d99eeef0b27460683831664b4ac68f5cf4f700cd), [#3536](https://github.com/heygen-com/hyperframes/pull/3536)).
+- **CLI:** Reject keyframe-shot outputs that would overwrite the active composition source ([e4dabf830](https://github.com/heygen-com/hyperframes/commit/e4dabf830c6cf377734de043d5f5345bcefe7b02), [#3534](https://github.com/heygen-com/hyperframes/pull/3534)).
+- **CLI:** Allow intentional `data-no-timeline` compositions without false frozen-sweep errors ([b28747df0](https://github.com/heygen-com/hyperframes/commit/b28747df0f2db9c5e7148e188a6ce6b99bcdda85), [#3533](https://github.com/heygen-com/hyperframes/pull/3533)).
