Codex App June 15, 2026 Changelog

The June 15, 2026 update for the ChatGPT iOS app is all about making the app a powerhouse for coding and complex projects on your phone. This release matters most to students or developers who use their phone to connect to a larger coding setup on their computer. It makes it much easier to navigate project files, understand code changes, and keep track of what the AI is doing behind the scenes.

What's new

• Workspace file browser: You can now look through your project files right from your phone and drop a file's location directly into your chat prompt.
• Folder picker: When you start a new chat, you can choose exactly which project folder on your computer the AI should be working in.
• Code change toggles: When the AI suggests changes to your code (called "diffs"), you can now expand or collapse all those changes at once to read them easily.
• Better permission choices: Sometimes the AI needs permission to run a tool. You can now choose to allow it just for your current chat or for all future chats. (This uses a system called MCP, which is just a standard way for the AI to connect to outside tools).
• Math formatting: The app can now properly display complex math formulas (using a typesetting system called LaTeX) right in the AI's messages and plans.

Improvements

• Clearer status icons: It's now much easier to see what the AI is doing, like when a task is running, waiting in line, or working on a background "subagent" (a smaller helper task).
• Easier phone-to-computer linking: Connecting your phone to your computer is smoother, with clearer error messages and a more reliable connection.
• Faster, better task recovery: If your connection drops, the app recovers your task lists and reconnects much better than before.
• Smoother goal tracking: Setting goals for the AI is easier with new keyboard shortcuts and better handling of follow-up questions.
• Cleaner menus: Your settings, profile sharing, and chat history layout have all been tidied up.

Fixes

• Frozen swipe actions: Fixed a glitch where swiping on a chat in your list would get stuck halfway.
• Duplicate messages: Fixed a bug where opening a new chat would accidentally show the same message twice.
• Messy task lists: Fixed an issue where background helper tasks (subagents) were incorrectly showing up at the top of your task list instead of staying organized under their main task.
• Fake connection errors: Fixed a problem where the app would say it couldn't connect, even when it was actually sending your message just fine.
