Cursor — September 2026 Releases
3 releases in September 2026.
What's new in Cursor, September 2026
Cursor adds self-hosted machines, Projects, and Rollouts and Security Review bots
Cursor's September 2026 releases added self-hosted agent infrastructure, a Projects feature for long-running work, and two bots for the last mile of shipping code. Three releases shipped, from v2026.09.02 to v2026.09.23.
Self-hosted machines keep tool execution inside your own network, with codebase, build outputs and secrets staying on internal machines. They can run as My Machines for personal use or as team pools that grow and shrink with demand and can hibernate idle workers. Self-hosted workers also support computer use on Linux and Mac. Projects, reached from the left-hand nav, uses a coordinator agent that plans work, delegates it to agents and returns finished work for review, running on a cloud computer so closing your laptop does not stop it. The month closed with Rollouts, which monitors each pull request through deployment, and Security Review, which reports exploitable bugs on every pull request. Both are available on Teams and Enterprise plans.
