The 29.0 line is stabilizing in public; 29.1 opens with load-tool work rather than engine work.
A side-by-side editorial comparison of GitHub and libheif — release velocity, themes, recent moves, and the top alternatives to consider.
Security and governance controls catch up to the Copilot build-out
GitHub's shipping split cleanly this window: platform security and governance on one side, Copilot model rotation on the other. Credential revocation now works by token type during an incident, OAuth apps can opt into expiring tokens with refresh, and enterprise managed settings reached Copilot for JetBrains. Code Quality gained a Trends tab at the organization level, and CodeQL 2.26.3 improved JavaScript, TypeScript and Vue modeling alongside GitHub Actions queries.
The HEIF library quietly became a video decoder, then a scientific image container.
libheif is at 1.22.0. Two releases in this window changed what the library is for: 1.21.0 added full read and write support for HEIF image sequences, which also lets it decode most MP4 video, and 1.22.0 opened a public API for arbitrary image components with signed, float and complex pixel types. The releases between them are build fixes and a maintenance patch.

The interesting work has moved from adding Copilot surfaces to governing them. Enterprise managed settings, MCP allowlists, and per-token-type revocation are all answers to the same question — how an administrator controls an agent fleet — and they are arriving faster than the agent features themselves now. Model additions have become routine catalogue maintenance, individually low-signal.
Expect enterprise managed settings to keep extending to the remaining Copilot clients, and OAuth token expiry to move from opt-in toward default once adoption data supports it. The weekly model cadence should continue with little signal in any single addition.

libheif is expanding along two axes at once — time, via sequences and an x264 encoder plugin, and channel semantics, via multi-spectral and filter-array data that has nothing to do with human vision. The ISO/IEC 23001-17 rewrite that picks the codec path from the input is what makes the second axis practical rather than theoretical.
The 1.22.0 notes say generic components are currently limited to the 23001-17 codec with JPEG 2000 to follow, so the next release most likely extends that component model to JPEG 2000 rather than opening a third front.
