The community keeps growing, and we'd love to see you there!

  • Join the discussion in Kubernetes Slack:
    • for questions and just to hang out

  • Fixed kube client logging issue #31560
  • Fixed regression where vendor-specific suffixes were stripped from .Capabilities.KubeVersion.GitVersion, breaking charts that detect managed Kubernetes platforms #31528
