-Kubernetes has two different package repositories starting from August 2023.
-The Google-hosted repository is deprecated and it's being replaced with the
-Kubernetes (community-owned) package repositories. The Kubernetes project strongly
-recommends using the Kubernetes community-owned package repositories, because the
-project plans to stop publishing packages to the Google-hosted repository in the future.
-
-There are some important considerations for the Kubernetes package repositories:
-
-- The Kubernetes package repositories contain packages beginning with those
-  Kubernetes versions that were still under support when the community took
-  over the package builds. This means that anything before v1.24.0 will only be
-  available in the Google-hosted repository.
-- There's a dedicated package repository for each Kubernetes minor version.
-  When upgrading to a different minor release, you must bear in mind that
-  the package repository details also change.

+Kubernetes has [new package repositories hosted at `pkgs.k8s.io`](/blog/2023/08/15/pkgs-k8s-io-introduction/)
+starting from August 2023. The legacy package repositories (`apt.kubernetes.io` and `yum.kubernetes.io`)
+have been frozen starting from September 13, 2023. Please read our 
+[deprecation and freezing announcement](/blog/2023/08/31/legacy-package-repository-deprecation/)
