Overview

Codex CLI version 0.114.0 introduces several experimental features and improvements designed to enhance developer workflows and platform reliability. The release includes new capabilities for code isolation, session management, and improved integrations with deployment infrastructure.

New Features

Experimental Code Mode

• Introduces an experimental code mode for more isolated coding workflows, allowing developers to run code in restricted environments with better separation of concerns.

Session Hooks Engine

• Adds an experimental hooks engine supporting SessionStart and Stop hook events, enabling developers to execute custom logic at critical points in the session lifecycle.

Health Check Improvements

Configuration Enhancements

• New config switch allows developers to disable bundled system skills entirely for more granular control over available capabilities.

Handoff Context Improvements

• Handoffs now carry realtime transcript context, improving continuity and context preservation when work is transferred between turns.

Refined Mention Picker
