Upgrading?
AI Summary
Studio now defaults to saving edits via the `@hyperframes/sdk` instead of older server handlers, and the GSAP script writer switches to 'acorn' by default. Both changes are configurable via environment variables.
Key Highlights
- Studio now defaults to SDK-based edit persistence, unifying the code path across Studio, AI Studio host, and agents.
- GSAP script writer switched from 'recast' to 'acorn'.
- Enhanced telemetry now records fallback reasons for edits that cannot be expressed as SDK operations.
- Player playback clock now handles main-thread stalling gracefully.
New Features
- Default SDK persistence for all edit families.
- Acorn-based GSAP script writing.
- Telemetry logging for edit fallbacks.
- Blur transform drivers and shutter-slam reference case.
Full Release Notes
# HyperFrames v0.8.47 Released on 2026-09-18. Studio now saves edits through the `@hyperframes/sdk` by default instead of the older server handlers. Every edit family is covered. The GSAP script writer is now acorn as well. Both can be turned off with an environment variable. ## Features - **Studio:** Every edit now persists through the SDK by default. The path previously shipped dark, so the engine was tested but never exercised by real sessions. Turning it on puts one code path behind Studio, the AI Studio host, and agents, instead of each consumer maintaining its own. An edit that cannot be expressed as an SDK operation still falls back to the server path, and now records why ([26ea8a074](https://github.com/heygen-com/hyperframes/commit/26ea8a0740a986383ce4aa7d2b399b992c838350)). - **Studio:** GSAP script writes use the acorn writer by default, replacing recast. Both produce the same result, and the old writer stays available for one release as a fallback before it is removed ([407cacf0a](https://github.com/heygen-com/hyperframes/commit/407cacf0aef3c498e79dc7eaa46b3f4bbfa52035)). - **Studio:** Telemetry now records every fallback and its reason, including the case where an element exists but could not be resolved for an edit ([9ef37e516](https://github.com/heygen-com/hyperframes/commit/9ef37e5163d861248ac3c158a5d612a3143a682f), [9f3a778fd](https://github.com/heygen-com/hyperframes/commit/9f3a778fd11b86186636729df8e4b5d964824789)). This is what makes it possible to tell whether the SDK is really handling edits or quietly handing them back. ## Fixes - **Player:** The interactive playback clock absorbs a main-thread stall instead of skipping past it ([2de3ca5f8](https://github.com/heygen-com/hyperframes/commit/2de3ca5f86da3b8bb2fdc3e62dd181c4ca565f55), [#4053](https://github.com/heygen-com/hyperframes/pull/4053)). ## Catalog - **Registry:** Blur every transform driver, and ship the reference case as shutter-slam ([82f49262e](https://github.com/heygen-com/hyperframes/commit/82f49262ec557a4160773df831dc5b228ac48a66), [#4038](https://github.com/heygen-com/hyperframes/pull/4038)). ## Full changelog https://github.com/heygen-com/hyperframes/compare/v0.8.46...v0.8.47
