Starting tomorrow, March 24, 2021, the mechanism we use to create GKE release notes will change. Although this change does not affect the content of the notes, it does affect the presentation and underlying syntax. If you subscribe to the XML feed for this page, entries for March 24 and earlier will be updated as a result of changes to formatting and syntax; the content itself did not change.

The feed URL will also change from https://cloud.google.com/feeds/kubernetes-engine-release-notes.xml to https://cloud.google.com/feeds/gke-main-release-notes.xml. We will automatically redirect from the old URL to the new one.
