# HyperFrames v0.8.69

By Steven Van · 2026-09-24

HyperFrames v0.8.69 speeds up linting and live preview updates, and fixes font, skill import, and video duration bugs.

HyperFrames version **0.8.69** speeds up linting on large compositions and cuts the delay between a file edit and its preview from 300ms to **30ms**. The release also fixes several bugs in font handling, skill imports, variable validation, and video duration.

- Lint findings on large compositions are now located in linear time.

- The CLI's --vars flag refuses a value of the wrong type instead of writing it.

- Script imports in installed skills are kept inside their own skill directories.

- The engine reconciles metadata duration after an extraction that delivers fewer frames.

- Deterministic font faces now win over font stylesheets loaded later, and captured font subsets are preserved.
