-We no longer care about importing the full commit history, so `--squash` should be used
-when submitting a `release-tools` update. Also make sure that the PR for that
-contains the automatically generated commit message in the PR description.
-It contains the list of individual commits that were squashed. The script from
-https://github.com/kubernetes-csi/csi-release-tools/issues/7 can create such
-PRs automatically.

-- `git subtree pull --squash --prefix=release-tools https://github.com/kubernetes-csi/csi-release-tools.git master` - update local copy to latest upstream (whenever upstream changes)
