The app builder now supports multiple chat conversations (threads) working on the same branch rather than a single thread per branch.

A thread is a single chat conversation with the agent in the Chat tab. Threads are intended to help you keep your work organized by task or theme. For example, use one thread for updating your app theme, and another thread for editing a chart on that page. Manage threads from the Chat tab.

A branch is a set of changes to your app, associated with an app preview, and with its own version history. A branch is the unit of work that you publish, and you create a new branch to begin a distinct line of work. For example, create a new branch when you want to change the resources that your app uses, or when you want to overhaul a page. Manage branches from the Version history tab in the navbar.

When using Source Control, branches in the protected app builder map to branches in your external git repository.
