Codex CLI 0.151.0-alpha.8

0.151.0-alpha.7→0.151.0-alpha.8·August 28, 2026 at 6:17 AM UTC

Prerelease 0.151.0-alpha.8: exec-server remote registration retry and JSONL event output work, auth-recovery notifications, and cleanup of a few models, config keys, and env flags.

Changelog

  • [new] Auth recovery events and notifications so clients can surface and handle authentication recovery flows.
  • [new] JSONL-oriented event processing on the exec path for structured, line-delimited event output.
  • [new] Remote registration retry support in the exec server for more resilient remote setup.
  • [new] Sleep-tool configuration via TOML (SleepToolConfigToml) for controlling sleep-tool behavior.
  • [new] Richer environment status/snapshot payloads (including EnvironmentStatus and an expanded environments snapshot).
  • [new] HTTP request body delta notifications and related realtime conversation event wiring.
  • [new] Token usage profile payload for reporting usage against a profile.
  • [changed] Exec-server relay/path layout: legacy noise-relay message framing and the old relay v1 protobuf path are gone in favor of the remote registration work.
  • [removed] The o1 model identifier is no longer listed.
  • [removed] The exclude_slash_tmp config key is no longer supported.
  • [removed] The CODEX_SANDBOX_NETWORK_DISABLED environment flag is no longer present.

Under the hood

  • New exec-server remote subsystem, including registration retry logic, replacing older relay proto/framing pieces.
  • Additional internal notifications/events (for example MITM hook denial and legacy rollout conversion failure) and small payload/type churn around traces, hooks, and filesystem path handling.
  • Env-var surface tightened around CI and exec-server controls (including CODEX_CI and exec-server stdin/URL/account-related knobs), with several older or renamed flags dropped.
  • Data-model updates for output diffs, raw payload refs, and synchronized update begin markers; assorted obsolete structs (such as daemon settings and older config-bundle/secrets request types) removed.
