OpenAI Codex CLI rust-v0.167.0

New Features

• Open the agent command center with codex agents --no-daemon. The command center and session picker now mark unread results (#58238, #58239, #58263, #58264).

• Switch between connected backends from the terminal session picker and keep your drafts when switching (#58280, #58457).

• Preview local image attachments while composing on supported terminals, and open viewed local images from clickable transcript paths (#58261, #58446).

• Find API key and cloud provider options under “Sign in another way.” Enable gcp_setup_wizard to set up Google Cloud Vertex AI with Application Default Credentials or a credential file (#57857, #58427).

• Opt into macOS or Windows system proxy settings from /experimental (#58157).

• Expand patch details directly in the transcript while an approval prompt is open (#58281).

Bug Fixes

• Saved chats stay visible after you switch model providers. If a chat can’t resume, you can read its transcript and prepare an editable prompt to continue in a new chat (#58202).

• Ctrl+L clears the terminal display while keeping earlier messages available through Ctrl+T (#58266).

• Deleting text that exposes a leading ! keeps an ordinary draft in chat mode (#58412).

• Network approval prompts close when their requests end. Concurrent requests to the same endpoint prompt one at a time (#58350, #58351).

• Long realtime V3 conversations save completed speech to chat history as the transcript grows (#58221).

• Automatic context compaction now accounts for retained output from failed responses and responses with missing token usage data (#58404).

Documentation

• The app-server README covers managed network constraints under [permissions.network] and prompt-user command rules that require fresh human approval (#58045, #58182).

• The openai-docs skill recommends the documented replacement when migrating away from a deprecated model (#58134).

Chores

• DotSlash manifests now reference the Cargo packages shipped with the release (#58717, #58757).

• Linux musl builds use fewer allocator arenas to reduce idle memory after conversations unload (#58399).
