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.

Long Term Support releases receive support and security updates for two years (instead of the usual one year). The first Long Term Support AKS release will be 1.27, to be released in May 2023.

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

More information is available on the Azure Kubernetes Service website.
