# HyperFrames v0.7.54

Released on 2026-07-12.

This release hardens the drawElement parallel-capture router with real-traffic safety rails — a machine-RAM floor, worker-count-scaled self-verify, and compile-time gates for ancestor background-images and HDR disk headroom — and extends parallel streaming to the non-drawElement screenshot/BeginFrame paths with cohort telemetry. It also closes a cluster of snapshot/check capture-fidelity gaps: remote fonts are localized and embedded to match the render, `check` now flags text that paints invisibly, and video-injection, canvas-motion, and shader-clone capture issues are surfaced or fixed.

## Features
