New Features

  • Save reusable prompts and slash commands in ten numbered /presets slots, with a keyboard menu for quick access.
  • Set model, reasoning effort, speed, and permission profiles directly with inline /model and /permissions arguments.
  • Preview viewed and generated images in the fullscreen transcript on terminals supporting Kitty or Sixel graphics.
  • Authenticate enterprise MCP connections using eligible Codex account grants or dedicated sign-in, including OAuth clients requiring secrets.
  • Mask credentials during supported remote Bash commands and Zsh snapshot sessions, including credentials from custom providers.
  • The Amazon Bedrock setup wizard is now enabled by default, with API key entry grouped alongside other AWS sign-in methods when credentials are detected.

Bug Fixes

  • Failed compaction no longer leaves partial summaries in conversation history, and background compaction failures fall back without panicking.
  • Resuming sessions now finds compressed histories and restores saved thread settings instead of replacing them with global defaults.
  • Windows HTTPS and WebSocket connections now handle proxy authentication challenges using the signed-in user’s Negotiate or NTLM credentials.
  • CLI configuration overrides are preserved when -c or --config appears at multiple subcommand levels.
  • Queued prompts now wait for pending permission selections to resolve before continuing.
  • Hardened sandbox checks for case-variant metadata paths on macOS and replaceable symlinks used to locate executables.

Chores

  • Reduced disk usage by pruning unused installations, cleaning abandoned marketplace checkouts, and bounding daemon logs.
  • Updated the embedded JavaScript runtime with safety checks for optimized Array.sort operations.
