Codex 0.146.0

Mid-project, you may need to ask a side question without muddying the main thread. /new and /clear can name a new session, important threads can be pinned, and side conversations can be opened without closing the original one. Think of labeled notes on a desk: keep the urgent one visible and put the detour on its own sheet, so you can return to the work where you left it.

If your team built an add-on that guides an agent through a repeatable job, it now has a clearer way to be packaged and shared. Codex supports Agent Plugin manifests, workspace publishing, and extra plugin marketplaces for Amazon Bedrock and Claude Code. It is like putting a label on a tool you made and placing it on a shared shelf: people can identify it, find it, and install it.

When one conversation suggests two approaches, you no longer need to rewind or start over without its context. You can fork a thread, carrying even a long paginated history into each branch; a temporary fork can stay out of the thread list. It is like photocopying a chapter of a novel: send the character left in version A and right in version B while the original stays on the desk.

When code runs on a remote host while the interface is in front of you, app-server can now connect to a remote Code Mode host through WebSocket, a connection that keeps both ends exchanging messages. Compatible custom model providers can also enable standalone web search. It is like staying in a control room with an open line to a distant workbench; using another model provider need not take web search away.

An executor connected for you may come with skills and supporting resources. Codex can now discover those skills and safely read the associated material, including skills you explicitly selected. A skill is a reusable set of instructions and knowledge for a particular job; seeing its name is not enough. This is like opening the manuals and safety labels in a borrowed toolbox before picking up a tool.

On a company network that requires a proxy, it is frustrating when sign-in works but downloads or remote runs fail. Configured proxies now apply to authentication, plugin downloads, MCP authorization, remote execution, WebSockets, redirects, and LM Studio connections. Documentation also covers shared HTTP clients, proxy-aware connection pools, and safe outbound requests. It is like an access card that now opens the whole building rather than only the front door.

Changing a sign-in or tool setting and then restarting everything is an irritating pause. MCP connections and Apps tools now update when authentication or configuration changes. Closed servers reconnect, while healthy connections keep running. It is like adjusting a home router: rooms that lost the network reconnect themselves, and a room already on a call does not have to hang up.

When a long response is interrupted, the worst part is not knowing what survived. This release preserves submitted messages, final responses, failed-turn errors, imported timestamps, and approval settings through interruptions, replay, imports, and forks. It is like a power cut during video editing: clips already on the timeline, their time markers, and permission choices remain when you reopen the project.

In a small laptop window or split pane, you do not want unresponsive keys, a crushed layout, or an interrupt that makes you wait. Terminal responsiveness and rendering improve here: interrupts need not block, keyboard handling is steadier, narrow layouts read better, and hyperlinks and mention results refresh. It is like rearranging a cramped cockpit so the brake is reachable and the instruments remain legible.

As a conversation grows, its context budget — the space a model can carry forward at once — can become tight, and the skill catalog may need shortening. This release retains more available skills and warns when truncation is unavoidable. It is like a suitcase nearing capacity: keep the useful tools on top, and clearly say what could not fit instead of pretending the whole kit made the trip.

Installing or updating a tool is more than following one download link. Release artifacts, channel metadata, and installer aliases can now be served through OpenAI-hosted release infrastructure, with GitHub as fallback. Bundled macOS helper executables are also signed and notarized before packaging. It is like sending a parcel through an official delivery route first, then a backup route if needed, with a seal that lets a Mac verify the included part.

For Codex updates in an enterprise, it matters not only whether a release exists, but which plan qualifies and who controls it. This release adds enterprise-plan recognition and administrator controls for in-app updates. It also reduces app-server serialization overhead and unnecessary request-building allocations. One change is like avoiding repeated packing before a shipment; the other is like a building manager deciding which floors receive an update and when.
