Codex

Scheduled tasks can now run on events from Gmail (filtered by sender or subject), Slack channels, or GitHub pull request activity. Connect the relevant apps, approve access, and create an event-triggered task; such tasks can't use a time-based schedule, and matching events may be combined into one run.

Codex now supports ChatGPT browser extension in Edge, Brave, Opera, and Vivaldi, plus site tools (WebMCP) in the built-in browser to work with web pages. On eligible plans, cloud browser sign-in lets you authenticate to supported websites through ChatGPT Work on web, iOS, and Android.

The codex mcp-server command is now deprecated. Use the Codex app server instead, or the Codex plugin for Claude Code when working from Claude Code.

Changelog

Full Changelog: rust-v0.149.0...rust-v0.149.1

Codex adds an Apple Messages plugin for reading and sending Messages chats on macOS, plus site co-editing with workspace editors. Also adds editable Site URLs, Computer History in Europe, and read-only shared thread snapshots.

New interactive codex agents dashboard for managing tasks, plus /cd, /pwd, /cwd working-directory commands, codex queue for messaging sessions, and expanded Vim editing. Includes fixes for queued-message wake-ups, session-name resolution, and TUI routing for sub-agents.

Codex cloud now connects to GitLab projects across all ChatGPT plans, letting users start tasks from issues or merge requests with @codex and request one-off or automatic merge request reviews. The integration requires a managed workspace admin to enable it, and GitLab Self-Managed or Dedicated setups need GitLab 19.0 or later.

New Features

Added a setting to open ChatGPT directly in Codex Remote on launch, plus support for standard MCP forms and editable message approvals. Fixed large task responses failing to load, tasks disappearing after idle or reconnect, and improved diff review stability and voice reliability.

Workspace owners and admins can download a CSV of public plugins visible to their workspace, including names, descriptions, developer, version, date added, and OpenAI verification metadata. Exports use a snapshot up to 48 hours old and exclude workspace-created plugins; unavailable in FedRAMP workspaces.

Computer History is a new opt-in feature in the ChatGPT desktop app on macOS that turns activity across apps and websites into memories and a timeline that ChatGPT and Codex can use. Choose which apps and websites contribute, pause collection, and review or delete your history at any time; available to ChatGPT Pro, Business, and Enterprise users, with Business and Enterprise admins needing to enable access first.

The ChatGPT desktop app for Linux is now available in preview for Ubuntu, Debian, and Fedora on x64 and ARM64, letting users work with projects, local files, and Codex. The desktop app and Codex CLI can import setup, settings, skills, plugins, projects, and recent work from Claude Code, Claude Cowork, and Cursor, with automatic sync options.

Daybreak now offers two separately approved access tiers for defenders: Daybreak Blue, providing general-purpose models like GPT-5.6 Sol for vulnerability discovery, secure code review, detection engineering, and incident response; and Daybreak Red, providing purpose-trained models like GPT-5.6 Cyber for authorized exploit validation, penetration testing, and red teaming. Both require approval through Trusted Access for Cyber, with Daybreak Red needing separate provisioning.

New Features

New tasks now preserve their first prompt and attachments while starting, and task reconnection is more reliable with visible progress. Voice conversations follow the Background Conversations setting, follow-up /goal prompts work after completing a goal, and editing long prompts is faster. Fixed task-list freezes, disappearing task titles, flashing thinking summaries, and transcript crashes.

Codex CLI now applies safer automatic-review defaults for cyber-capable models and explains the permission changes in the terminal interface.

Record & Replay is now available in the European Union, the United Kingdom, and Switzerland. On macOS, demonstrate a workflow to turn it into a reusable skill; Computer Use must also be available and enabled.

GPT-5.4 and GPT-5.4 mini will be removed from Codex for ChatGPT-signed-in users on August 31, 2026. Replace gpt-5.4 with gpt-5.6-terra and gpt-5.4-mini with gpt-5.6-luna.

Review changes across multiple repositories in a single project view, refine generated images with an expanded viewer and comment capabilities, and search browser history from the address bar. Plus improved Windows installation reliability and a new Activity view in the sidebar.

Sign in with ChatGPT is rolling out in beta, allowing users to create or link accounts with supported plugins and partner sites including Airtable, GitLab, HubSpot, Notion, Supabase, and Vercel. Partners receive only name, email, and profile picture; plugin access approval remains a separate step.
