  • [8464] Fixed the issue with Helm controller and OIDC integration failing to be deleted during detach of an MKE cluster.

  • [9928] [Ceph] Fixed the issue with Ceph rebalance leading to data loss during a managed cluster update by implementing the maintenance label to be set before and unset after the cluster update.
