Codex CLI 0.153.0-alpha.1

0.152.0→0.153.0-alpha.1·September 1, 2026 at 6:17 AM UTC

Alpha prerelease (0.153.0-alpha.1) with early groundwork for plugin reconciliation, ChatGPT turn-cost tracking, guardian context/feedback, and richer realtime session history.

Changelog

  • [new] Plugin reconciliation support on the app server, including a dedicated reconcile request path for keeping plugin state in sync.
  • [new] ChatGPT turn-cost reporting: backend client and worker support for fetching and handling per-turn cost data.
  • [new] Guardian feedback upload handling, including a response type for feedback submissions.
  • [new] Realtime session history updates, including transcript delta events for live history streaming.
  • [new] TUI reconnect support so the terminal UI can recover a session connection more cleanly.
  • [new] Token usage records in rollout/wire data (usage profile and per-record usage) for finer-grained tracking.
  • [new] mitm_hook_denied event surface for denied MITM-hook cases.
  • [changed] Compacted rollout items and turn-context payloads carry additional fields for richer session/turn metadata.
  • [changed] Auto-review message payloads expanded slightly.
  • [removed] Older realtime event-handling path in the app server in favor of the newer session history flow.

Under the hood

  • New guardian-context crate, including truncation helpers for guardian-related context handling.
  • Exec-server noise relay gains explicit message-framing support.
  • Installed-app modeling adjusted (structured installed-app records in place of the prior apps-installed response shape).
  • Rollout wire types extended (for example token-usage records and related line/item variants).
  • Assorted enum and client-event refinements (including chunked client message results); some older ack/result and hook-handler variants were dropped or replaced.
  • Dependency set trimmed slightly (removed event-listener-strategy).
  • Build metadata moved to the alpha channel for 0.153.0-alpha.1.
