  • breakingSupported Kubernetes versions

    Applies if you use Kubernetes versions outside v1.30 through v1.35.

    Rook v1.19.0 supports Kubernetes versions v1.30 through v1.35.

  • breakingThe activeStandby property behavior

    Applies if your CephFilesystem CRD sets activeStandby to false.

    In the CephFilesystem CRD, setting activeStandby to false now scales down and removes the standby MDS daemon deployment. Previously, this setting only disabled the standby cache while the daemon remained running.

  • breakingAutomatic CSI Ceph client creation

    Applies if you run Rook in external mode and provide a Ceph admin keyring.

    In external mode, Rook no longer creates CSI Ceph clients automatically when users provide a Ceph admin keyring.
