Breaking Changes

The supported Kubernetes versions are v1.30 - v1.35
The minimum supported Ceph version is v19.2.0. Rook v1.18 clusters running Ceph v18 must upgrade to Ceph v19.2.0 or higher before upgrading Rook.
The behavior of the activeStandby property in the CephFilesystem CRD has changed. When set to false, the standby MDS daemon deployment will be scaled down and removed, rather than only disabling the standby cache while the daemon remains running.
Helm: The rook-ceph-cluster chart has changed where the Ceph image is defined, to allow separate settings for the repository and tag. For more details, see the Rook upgrade guide.
