Announcements

• Starting with this release, the pod memory limit for Azure NPM has been increased from 300 MB to 1 GB for clusters with the uptime SLA enabled. Requests will stay at 300 MB.
• Starting with Kubernetes 1.24, the following changes will be made default:
  • The default format of clusterUser credential for AAD enabled clusters will be ‘exec’, which requires kubelogin binary in the execution PATH. If you are using Azure CLI, it will prompt users to download kubelogin. There will be no behavior change for non-AAD clusters, or AAD clusters whose version is older than 1.24. Existing downloaded kubeconfig will still work. We provide an optional query parameter ‘format’ when getting clusterUser credential to overwrite the default behavior change, you can explicitly specify format to ‘azure’ to get old format kubeconfig.
  • The NodeRestriction Admission Controller will be enabled. This will allow users to enable/disable node restriction.
  • CoreDNS version 1.9.2 will be default version. With this new version of CoreDNS wildcard queries are no longer allowed.
  • metrics-server version 0.6.1 will be the default version.
  • metrics-server vertical pod autoscaler will be enabled.
• Kubernetes 1.21 version deprecation will start taking effect from July 31st, 2022.
