OpenAI Codex release notes: 0.157.0 forks locked conversations

OpenAI Codex CLI 0.157.0 lets you continue a conversation open in another app by creating an editable copy. Your local drafts and queued prompts come with it. Codex CLI is OpenAI's terminal-based coding agent.

OpenAI Codex release notes: continue in your own copy

When another app has the conversation open, the composer is locked. Version 0.157.0 adds the f shortcut to that view. It creates a fork, a separate copy of the conversation where you can keep working without taking the original away from the other app.

The release was published on September 25 and is the stable npm version at the time of checking.

Human step: press f in the locked view

In Codex CLI 0.157.0, press f or F while viewing a conversation open in another app. Codex displays "Forking conversation…" while it creates the copy, then "Fork created. You can continue here."

Local drafts and queued prompts are preserved in the copy. If the attempt fails, Codex keeps the locked view and your draft intact. This is an interface action, not an instruction to the agent.

Full-screen view becomes the default in 0.157.0

Version 0.156.0 introduced an optional full-screen transcript view. In 0.157.0, it is on by default. Alternate-screen restrictions still take precedence. The setting tui.fullscreen_transcript=false restores terminal scrollback.

You can also extend an existing text selection with Shift-click. An ordinary click starts a new selection.
