AO2 v0.5.8 Stable Patch Release Notes
AO2 v0.5.8 strengthens pre-commit and pre-push quality gates, external issue
repair evidence, installation recovery, archive updates, build identity, and
physical-Windows qualification. AO2 Control Plane v0.1.19 is its supported
companion release.
Changes Since v0.5.7
- Adds exact staged, outgoing-commit, and source-head quality execution with
optional repository hooks and fail-closed Git-state checks. - Binds external issue repair packs to machine-generated reproduction evidence.
- Hardens install transaction recovery, custom-install doctor discovery, and
public archive update behavior. - Adds Rust supply-chain evidence and exact Git-ref build identity monitoring.
- Rejects malformed physical-Windows worker results and binds qualification to
lifecycle cleanup and worker provenance.
Supported Archives
- macOS aarch64
- Linux x86_64
- Windows x86_64
Linux aarch64 hosts may use the Linux x86_64 archive under explicit Docker
emulation. AO2 v0.5.8 does not publish a Linux aarch64 archive.
Verify the downloaded archive against SHA256SUMS before installation. The
credential-free fixture workflow remains available for local evaluation.
Rollback uses ao2 install rollback; AO2 Control Plane remains a read-only
observer and does not approve or publish AO2 releases.
