+Trimming a scene in Studio keeps its length, and an edit reaches the preview even when a reload is slow. Renders report progress from the first frame, and projects whose names contain @, %, #, & or ? now load.

+- **Studio:** An embedder can change what the shortcuts panel lists ([881481f56](https://github.com/heygen-com/hyperframes/commit/881481f56b2682a62dc64b75a1237bc5e06a9bb7), [#4416](https://github.com/heygen-com/hyperframes/pull/4416)).

+## Fixes
+
+- **Studio:** Trimming a scene no longer shrinks it to the length of a video inside ([a3d7736d4](https://github.com/heygen-com/hyperframes/commit/a3d7736d40ab5a4273fa1dda40d27a66bdad1bcf), [#4421](https://github.com/heygen-com/hyperframes/pull/4421)).
+- **Engine:** Download tests stop racing real deadlines, and failures name their cause ([cbaddec51](https://github.com/heygen-com/hyperframes/commit/cbaddec51a45e836b498a56c32c2901b33d806ff), [#4419](https://github.com/heygen-com/hyperframes/pull/4419)).

+- **Studio:** An edit still reaches the preview when its reload is slow ([1926903b6](https://github.com/heygen-com/hyperframes/commit/1926903b6a5707d47de09b00faf9421bb8d94d08), [#4418](https://github.com/heygen-com/hyperframes/pull/4418)).
