v0.5.9
codex-peer v0.5.9
This release requires Sessionbus v0.5.9 (daemon and hub) and pins the Sessionbus Go SDK v0.5.9. The version matches core v0.5.9.
Breaking, a flag day. The unreleased lane policy field idle_message is removed from the protocol and the SDK; message wake is mandatory. This peer requires a v0.5.9 daemon. Peers built with SDK v0.5.7 or earlier are incompatible with it. Upgrade the hub, the host daemons and the product integrations together. Follow the upgrade steps, including the offline lane-row edit, in the core v0.5.8 release notes. v0.5.9 has the same runtime as v0.5.8.
Fixes:
- Typed argument conflicts are rejected before launch. A typed lane
modelorreasoning_effortcombined with a raw native argument that selects the same setting (for examplemodelplus--model) now fails spawn withargument conflicts with typed field <name>. Before this, it reachedcodex app-serverand failed late. Untyped native arguments are unchanged, and parsing stops at--. codex-peer --native-versionruns native Codex directly. It no longer starts a broker or App Server, and creates no launch directory. The exec strips allSESSIONBUS_*variables.
scripts/install-codex.sh installs the latest release by default, so it now installs v0.5.9. Pin SESSIONBUS_VERSION on hosts that are not yet in their upgrade window. The legacy per-product installers inherited from the combined repository (scripts/install-{claude,grok,qwen,opencode,kilo,pi,omp}.sh) are removed. They installed the combined v0.5.3 peers, which are incompatible with Sessionbus v0.5.8 and later. Use each product repository's installer. The historical combined releases and assets remain available.
