# HyperFrames v0.6.115

Released on 2026-06-20.

Full slideshow stack: schema, parser, controller, `<hyperframes-slideshow>` web component, presenter mode, branching editor panel, and `hyperframes present` CLI command. SDK gains element add/remove ops, elastic timing, keyframe writers, variables/brand model, and image-alpha hit-testing. Fixes cross-realm iframe media handling, per-element audio muting, querySelector injection, and DOM edit parity.
