Cursor 3 drops with agents, cloud handoff

Cursor 3 is a category-defining pivot that treats AI agents as primary collaborators rather than sidebar assistants.

• –The new Agents Window enables persistent, background execution across multiple repositories, moving beyond the single-file context of traditional IDEs.
• –Cloud-local handoff allows developers to start a complex refactor on their machine and finish it in the cloud, maintaining state and session context.
• –Native worktree support and the /best-of-n command allow for safe, parallel experimentation without cluttering the main branch.
• –Support for self-hosted cloud agents and granular enterprise controls solve critical security and sovereignty blockers for large teams.
• –By integrating an internal browser and mobile/web triggers, Cursor is effectively building a "remote control" for codebases.
