Codex CLI 0.148.0-alpha.23

0.148.0-alpha.22→0.148.0-alpha.23·August 18, 2026 at 10:16 PM UTC

Alpha release that adds codex exec-server forward so you can register an existing WebSocket exec-server as a remote environment.

Changelog

  • [new] codex exec-server forward registers an already-running WebSocket exec-server as a remote environment via --connect (destination exec-server WebSocket URL), with the usual remote registration options (--remote, --environment-id, --name, agent-identity auth, config overrides).
  • [changed] Bash, fish, and zsh completions include the new exec-server forward subcommand and its flags.
  • [removed] The exclude_slash_tmp config key is no longer recognized.

Under the hood

  • Exec-server gains a dedicated forward path and noise-relay stream handling for remote registration flows.
  • Exec adds a JSONL-oriented event processor for structured run output.
  • Realtime conversation work continues with a sideband channel path.
  • Client/protocol surface is trimmed (legacy client message/ack-style events dropped) and several internal request/response shapes are refreshed, including MCP resource read payloads and related capability/model list types.
  • OpenTelemetry exporter options and other internal enums/hooks continue to evolve ahead of broader runtime use.
