+// information from git.
+//
+// If you are looking at these fields in the git tree, they look
+// strange. They are modified on the fly by the build process. The
+// in-tree values are dummy values used for "git archive", which also
+// works for GitHub tar downloads.
+//
+// When releasing a new Kubernetes version, this file is updated by
+// build/mark_new_version.sh to reflect the new version, and then a
+// git annotated tag (using format vX.Y where X == Major version and Y
+// == Minor version) is created to point to the commit that updates
+// pkg/version/base.go

+	// translation to be semver compliant.
