v0.7.77

HyperFrames v0.7.77

Released on 2026-07-28.

Studio's timeline now exposes expandable property lanes, track headers, precise
keyframe retiming, and selection-safe editing across nested compositions. This
release also makes stalled CLI download cleanup reliable on Windows and adds an
opt-in prose-coverage floor to layout checks.

Features

• Studio: Add expanded keyframe lanes, track headers, retiming interactions,
  and nested-composition timeline support
  (#2791)
• Check: Add the opt-in proseCoverageFloor layout rule
  (#2834)

Fixes

• CLI: Wait for stalled download pipelines to release temporary files before
  cleanup, fixing the Windows locked-file failure
  (#2835)
• Telemetry: Send CLI feedback through the plain-event path instead of the
  PostHog survey API
  (#2831)

Performance

• CI: Distribute the two heaviest render fixtures and improve Docker layer
  reuse for producer-only changes
  (#2825,
  #2822)

Docs & Examples

• Send-to guide: Clarify that enhance turns are free and rendering is the
  paid step
  (#2827)

Internal

• CLI: Separate telemetry delivery from event policy while preserving the
  queued flush and process-exit behavior
  (#2344)
