For a full list of changes, review the release notes on GitHub: Release v6.3.0.

New

  • Custom add-ons for platform admins — Platform administrators can now deploy their own Kubernetes applications into the apl-addons namespace. This gives admins a supported, first-class way to install custom tooling alongside the platform without workarounds.

Changed

  • DNS and certificate settings — Fixed a rendering bug that could cause external-dns and cert-manager configuration to be applied incorrectly.
  • More accurate platform ready status — When installing App Platform with Helm, the operator can be configured to only report "ready" after the initial installation is fully complete. To do this, set operator.readiness.gateOnReadines=true.
  • Updated core applications — See the Core application changes table below for details.

Deprecated

  • Kubeflow Pipelines has been deprecated.
