OpenAI Codex CLI v0.143.0 Changelog

This update is all about making the Codex CLI (a command-line tool that lets developers interact with OpenAI's coding AI) more flexible, secure, and easier to connect to other tools. If you are a developer using Codex to write code, this release makes it much easier to use online add-ons, run Codex behind school or office security networks, and try out powerful new AI models.

What's new

• Online Plugins by Default: Plugins—which are like mini-apps that give Codex extra skills—are now turned on by default. You can now browse them easily, see if you have the latest version, and load them from popular online registries.
• New AI Models: Codex now supports Amazon Bedrock's "Sol," "Terra," and "Luna" models. You can also set these models to use "maximum reasoning," which tells the AI to think as deeply as possible before answering.
• Easier Device Pairing: Added a new command (codex remote-control pair) that lets you quickly generate a code to link your current Codex session to another device.
• Smarter Tool Searching: Codex uses a system called MCP (Model Context Protocol) to use external tools (like file readers). Now, it can search for these tools automatically and log into them more securely.
• Better Conversation Control: Developers can now inspect the virtual environments Codex is running in, look at different conversation paths, and "fork" (split) a conversation history at a specific point to try a different coding approach.

Improvements

• Better Network Support: Codex can now automatically route its internet traffic through macOS and Windows system proxies (special security servers often used by schools and offices), so you don't have to configure them manually.
• Security Updates: Several behind-the-scenes code libraries (like OpenSSL) were updated to keep the tool safe from security vulnerabilities.
• More Reliable Installer: The installer is now smarter about how it downloads updates, meaning it won't get blocked as easily when GitHub's servers are busy.

Fixes

• Windows Typing Glitches: Fixed annoying bugs on Windows where pressing backspace or enter in the terminal didn't work quite right.
• Frozen Loading Screens: Fixed an issue where the text interface would look like it was frozen or "busy" when starting up or waiting for safety approvals.
• Network Spam Prevention: Stopped Codex from spamming the network with login requests if its connection to the server was temporarily lost.
• No Lost Text on Shutdown: Fixed a bug where the very last lines of a live text transcript would disappear if you closed the app.
