# HyperFrames v0.7.45

Released on 2026-07-09.

SDK gains three exports (`getRootElements`, `isNewHostBoundary`, `bareId`) and a `serialize({ stripRuntime })` option, plus a fix for `data-start` relative-timing references that used to silently resolve to 0. Studio's storyboard, crop tool, and color grading also land this release.
