+// Base version information.

+// This is the fallback data used when version information from git is not
+// provided via go ldflags. It provides an approximation of the Kubernetes
+// version for ad-hoc builds (e.g. `go build`) that cannot get the version
+// 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
+var (
+	// TODO: Deprecate gitMajor and gitMinor, use only gitVersion
+	// instead. First step in deprecation, keep the fields but make

+	// translation to be semver compliant.
