Release notes

• Preview Features

  • Stop cluster minor version upgrades on API breaking changes is now available in preview. AKS will fail fast on minor version manual upgrades if it detects usages of deprecated APIs in the target version of the upgrade. This is available when target cluster for upgrade is >= 1.26.0, when the API request for cluster is using API version >= 2023-01-02-preview, and when usage of API breaking changes has been detected in the 12 hours prior to the upgrade.

• Bug Fix

  • Fixed an issue where kube-scheduler would crash on AKS clusters of version 1.25+ when there are inline volumes in the cluster.
  • Fixed an issue where it was not possible to rotate certificates for stopped AKS clusters.
  • When installing Cilium Enterprise through Azure Marketplace, AKS validates that if the extension is from an Isovalent offer, then the extension name must be "cilium". The extension name error message has been clarified to reflect this requirement.
