Cursor 3 (cursor.com) AI

Cursor has released Cursor 3, a redesigned, agent-first workspace intended to make it easier to manage work across multiple repositories and both local and cloud agents. The update adds a unified agents sidebar (including agents started from tools like GitHub and Slack), faster switching between local and cloud sessions, and improved PR workflows with a new diffs view. It also brings deeper code navigation (via full LSPs), an integrated browser, and support for installing plugins from the Cursor Marketplace.
