Codex CLI 0.155.0-alpha.11

0.155.0-alpha.10→0.155.0-alpha.11·September 16, 2026 at 6:17 PM UTC

Patch alpha release: adds an internal tcp-tunnel command for HTTP/3 CONNECT proxying, plus a /daemon slash command and supporting protocol/config groundwork.

Changelog

  • [new] codex tcp-tunnel — Internal subcommand that forwards a local TCP socket through an HTTP/3 CONNECT proxy. Configure the proxy origin (--proxy-url), optional approved-origins file (--proxy-origins-file), CONNECT target (--target), and listen address (--listen-addr). Auth and CONNECT headers can be supplied on stdin (--auth-token-stdin, --auth-token-updates-stdin, --connect-headers-stdin), with the usual --config / --enable / --disable overrides. Shell completions (bash, zsh, fish) include the new command.
  • [new] /daemon slash command — New interactive slash command for daemon-related workflows.
  • [changed] Remote client events — Remote session traffic now uses an ack-style client event path in place of the previous chunked client-message event.
  • [new] TUI suspend failure signal — The process layer can surface a tui_suspend_failed notification when suspending the terminal UI does not succeed.

Under the hood

  • New tcp-tunnel workspace crate implements the tunnel path on QUIC/HTTP/3 (via Quinn and related crates) with connection bookkeeping support.
  • Config and API surface expands for context management, tool choice, follow-up task args, application requirements / apps list responses, and thread unarchive payloads.
  • Model-provider workspace routing module removed; minor TUI analytics palette cleanup.
  • Dependency lockfiles and version metadata bumped to 0.155.0-alpha.11.
