New Features

  • GPT-6.1 Sol is now the default model in the bundled and Amazon Bedrock catalogs.
  • Amazon Bedrock supports multi-agent V2 and Ultra reasoning on compatible models; Bedrock Mantle also accepts AWS GovCloud regions.
  • Sign in to MCP servers from an active terminal session with /mcp login <name>.
  • Choose your microphone, speaker, and microphone input channels for voice conversations, with preferences saved locally.
  • Daybreak is opt-in through --enable cli_daybreak or features.cli_daybreak=true; daybreak=true alone is insufficient. By default, controls and indicators are hidden, /daybreak is unavailable, and automatic Cyber routing is omitted—even for saved Daybreak threads. Saved preferences remain intact. Opt-in routing requires eligible ChatGPT sign-in, the OpenAI provider, and advertised model/program support.
  • Select a Cyber access program per turn with codex exec --cyber-access-program or the TypeScript SDK’s cyberAccessProgram option. The explicit exec override remains available with cli_daybreak disabled and leaves the saved choice unchanged.

Bug Fixes

  • Approved filesystem escalation can now grant broader write access while preserving denied reads and network restrictions. Background tasks retain their originating turn’s permissions.
  • Explicit launch permissions survive terminal reconnects and new sessions, while implicit client settings no longer overwrite server or saved-thread web-search settings.
  • Elevated Windows terminal sessions can start using an embedded server, and sandboxed PowerShell preserves relative paths beneath protected user profiles.
  • Enter correctly submits buffered input after paste detection expires, including in Vim insert mode.
  • Thread resume includes the latest committed history. Startup detects recoverable SQLite corruption earlier and preserves damaged databases as backups.
  • Responses retries and WebSocket-to-HTTP fallback honor server retry guidance, reducing premature failures during overload.

Documentation

  • Authentication guidance now accounts for keyring storage instead of implying credentials always reside in auth.json.

Chores

  • Publishing an older alpha or hotfix no longer moves npm alpha tags backward.
