Camunda 8 SaaS customers can enable auto-updates. When enabled, the cluster is updated once a new patch release is available.
For Camunda 8 SaaS, auto-updates are only for patch releases (x.y.z, where z is a patch release).
Minor updates (x.y.z, where y is a minor release) are not eligible for auto-updates and require manual steps to initiate. Depending on your role, you may see that an update is available, but no Update cluster button. Contact your organization owner or admin to update your cluster.
