 description: Describes how to set up automatic agent updates.

+We strongly recommend that Teleport users set up automatic agent updates to
+ensure that the version of Teleport running on agents remains compatible with
+the version running on the Auth Service and Proxy Service. If an agent does not
+maintain [version compatibility](./overview.mdx) with your Teleport cluster,
+connections to those agents will become degraded or lost.
+
+Cloud-hosted Teleport clusters are updated on a weekly basis. Major version
+updates are performed every 4 months. You can monitor and subscribe to the
+[Teleport Status](https://status.teleport.sh/) page to be notified of scheduled
+updates.

 Teleport supports automatic agent updates for systemd-based Linux distributions
 using `apt`, `yum`, and `zypper` package managers, as well as Kubernetes
 clusters.
