# Changelog

> Release notes for HyperFrames.

Recent HyperFrames releases, including user-facing features, fixes, and migration notes.

<Update label="HyperFrames v0.6.71" description="Released - 2026-06-04" tags={["Release", "Engine", "CLI", "Docs"]}>
  Fixes three production-observed CLI and engine errors: EPIPE crashes in piped agent environments, `@puppeteer/browsers` import failures that blocked all commands when the debug package was missing, and zero-duration composition timeouts reduced from 45s to \~11s with an actionable diagnostic.

  ## Features

  * **Docs:** Add weekly update drafts ([1abe69f3](https://github.com/heygen-com/hyperframes/commit/1abe69f3e479b41a804ee651e2874f31b150a4e8), [#1183](https://github.com/heygen-com/hyperframes/pull/1183))

</Update>

<Update label="HyperFrames v0.6.52" description="Released - 2026-05-27" tags={["Release", "Studio", "Producer", "Core"]}>
  This release focuses on stability improvements across Studio rendering, producer telemetry, and core timeline handling.

  ## Fixed

  * **Studio:** Added an FFmpeg pre-flight check before rendering so setup issues fail earlier with a clearer path to resolution.
  * **Producer:** Normalized structured error messages so telemetry and logs no longer collapse details into `[object Object]`.
  * **Core:** Guarded timeline method calls for non-conformant timeline-like objects.
  * **Release:** Removed a stale marketplace version field from packaged release metadata.
