# HyperFrames v0.8.212

By Steven Van · 2026-10-28

The v0.8.212 CLI release adds download resume, a unified --json error format and a help command, plus fixes across Studio, Inspector and Engine.

A model download that stalls partway through now resumes instead of failing. [HyperFrames](<https://creatorstoolbox.com/resources/hyperframes>) v0.8.212 also gives --json failures a single response shape, and check now shows progress while it runs, per the [changelog](<https://hyperframes.heygen.com/changelog#hyper-frames-v0-8-212>).

## CLI

- A model download that stalls partway resumes rather than failing.

- Every --json failure answers with one envelope, and --json is accepted only where it is supported.

- Remaining flag validation errors now exit with code 2.

- New help \[cmd\] command. The CLI suggests the closest command or flag, and its nags are quieter.

- check prints a progress line as each pass after overlap begins.

- check pages force a WebGL drawing buffer but keep no list of 2d canvases.

- snapshot warns when a video on screen has no source to read a frame from.

## Studio, Inspector and Engine

- Inspector: live queries see every composition, wherever the playhead is.

- Studio: a thumbnail reader forgets a start's failures after a minute.

- Studio Server: the render route passes a MOV ProRes profile to the render.

- Engine: a Windows browser that will not start now says where and why.

The release also includes two internal changes: a Studio test fix for undo timing, and keeping the bun cache warm while skipping binary downloads in preflight.
