👌 Kubernetes version support

  • Management Cluster: v1.24.x -> v1.27.x
  • Workload Cluster: v1.22.x -> v1.27.x

More information about version support can be found here

Highlights

  • MS preflight checks to improve cluster stability (behind feature gate).
  • Support for concurrent MachineDeployment upgrades in classy clusters.
  • Support for add-on providers in clusterctl.
  • Performance improvements when using CAPI at scale, new dev-tools and a new in-memory infrastructure provider for scale testing.
  • MachinePool Machines improve MachinePool observability.
  • clusterctl plugins allow custom code to be called from clusterctl.
  • More metrics have been enabled through a custom Kube State Metrics config, and example Grafana, Prometheus and other observability tool configurations have been added to the repo.
  • Cluster controller now avoids double rollouts during Kubernetes upgrades of classy clusters.

Deprecation warning

The API version v1alpha3 is no longer served in this release. API version v1alpha4 is deprecated and will be removed in v1.6.
