Full Release Notes

# HyperFrames v0.8.167

Released on 2026-10-16.

Long projects preview more smoothly: the preview's work now follows what is playing, not the total clip count. Bundling a project also stops freezing the app that runs it.

## Fixes

- **Core:** Bundling a project no longer blocks the host's thread on esbuild ([b1cf6e3c517](https://github.com/heygen-com/hyperframes/commit/b1cf6e3c517e227d1dca1b212e7637c19e502a64), [#5714](https://github.com/heygen-com/hyperframes/pull/5714)).
- **CLI:** Page loads stop timing out while a busy machine's Chrome warms up ([41486b9725a](https://github.com/heygen-com/hyperframes/commit/41486b9725ab2aae4f457d75dcd625931d103bb3), [#5705](https://github.com/heygen-com/hyperframes/pull/5705)).

## Performance

- **Core:** Hold a clip at 0 inside a later scene until it is due ([13ea8349597](https://github.com/heygen-com/hyperframes/commit/13ea8349597bbcb874402d1771aea65766fd7ffc), [#5716](https://github.com/heygen-com/hyperframes/pull/5716)).
- **Core:** A preview's composition scripts give the page a turn every 50 ms, not one long task ([12d8df37f4d](https://github.com/heygen-com/hyperframes/commit/12d8df37f4db8ccf019da32c97cc1352f8db9652), [#5713](https://github.com/heygen-com/hyperframes/pull/5713)).
- **Lint:** Strip stylesheet comments once per canvas zoom scan ([0bff8342c38](https://github.com/heygen-com/hyperframes/commit/0bff8342c389c1841d3b8d858168700f13627e48), [#5712](https://github.com/heygen-com/hyperframes/pull/5712)).
- **Core:** Preview runtime scales with what plays, not with the film's clip count ([d05bc4215d5](https://github.com/heygen-com/hyperframes/commit/d05bc4215d5757da86956217f4a8a4b2ab11b1fd), [#5674](https://github.com/heygen-com/hyperframes/pull/5674)).

## Internal

- **CLI:** Caption image test checks the close itself, not a reusable file number ([eace3d28b6c](https://github.com/heygen-com/hyperframes/commit/eace3d28b6cb721ec1f9a96d7d2ea76bf215551a), [#5707](https://github.com/heygen-com/hyperframes/pull/5707)).
