-  # This uses the `GithubLatest` strategy to work around an old `v2.2.3` tag
-  # that is always seen as newer than the latest version. If Skaffold ever
-  # reaches version 2.2.3, we can switch back to the `Git` strategy.
+  # The `strategy` code below can be removed if/when this software exceeds
+  # version 2.2.3. Until then, it's used to omit an older tag that would always
+  # be treated as newest.
