AKS defines a generally available version as a version enabled in all SLO or SLA measurements and available in all regions. AKS supports three GA minor versions of Kubernetes:

  • The latest GA minor version released in AKS.
  • Two previous minor versions.

Each supported minor version also supports a maximum of two stable patches.

AKS release notes are available on https://github.com/Azure/AKS/. News about AKS can be received by following the AKS feed in Azure Updates. Release status by regions can be monitored at AKS-Release-Tracker. AKS Docs include an Upgrade Guide.

Note that Calico isn’t supported in AKS 1.25 and above.
