# HyperFrames v0.7.42

Released on 2026-07-07.

This release switches drawElement fast capture to single-worker streaming after benchmarks showed multi-page parallelism losing to priority inversion, and makes Windows rendering reliable by copying extracted frames when symlinks hit EPERM. It also hardens the CLI: render fps defaults to the composition's `data-fps`, corrupt browser downloads self-heal, and upgrade notices match the detected install method.

## Features

- **Producer,cli:** DrawElement priority inversion — single-worker streaming over auto-parallel ([924727a0b](https://github.com/heygen-com/hyperframes/commit/924727a0b462b63c28c68a5fdf971ba7a6b1a369), [#2026](https://github.com/heygen-com/hyperframes/pull/2026))
