Announcements

  • No new clusters can be created with Azure AD Integration (legacy). Existing AKS clusters with Azure Active Directory integration will keep working. All Azure AD Integration (legacy) AKS clusters will be migrated to AKS-managed Azure AD automatically starting from 1st Dec. 2023. We recommend updating your cluster with AKS-managed Azure AD before 1 Dec 2023. This way you can manage the API server downtime during non-business hours.

Release notes

  • Behavioral changes

    • Update admissions enforcer to ignore "kubernetes.azure.com/managedby" and "control-plane" namespaces to fix this issue.
    • "kubernetes.azure.com/managedby" label added to aks managed namespaces (kube-system, gatekeeper-system, tigera-system, calico-system)
    • Stopped nodepools will be upgraded during an Auto Upgrade operation. The upgrade will apply to nodes when the nodepool is started.
    • Added priorityClassName system-node-critical property to all KEDA add-on pods to fix this issue.
    • We will now check that your cluster has less than 400 nodes when an upgrade operation is requested and using Kubenet (400 being the node limit for Kubenet).
  • Bug Fixes

    • Enable HonorPVReclaimPolicy for Azure Disk CSI driver 1.28, fixing an issue where in some Bound Persistent Volume (PV) – Persistent Volume Claim (PVC) pairs, the ordering of PV-PVC deletion determines whether the PV delete reclaim policy is honored.
