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.

Cheat sheet:

- `git subtree add --prefix=release-tools https://github.com/kubernetes-csi/csi-release-tools.git master` - add release tools to a repo which does not have them yet (only once)
- `git subtree pull --prefix=release-tools https://github.com/kubernetes-csi/csi-release-tools.git master` - update local copy to latest upstream (whenever upstream changes)
- `git subtree add --squash --prefix=release-tools https://github.com/kubernetes-csi/csi-release-tools.git master` - add release tools to a repo which does not have them yet (only once)
- `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)
- edit, `git commit`, `git subtree push --prefix=release-tools git@github.com:<user>/csi-release-tools.git <my-new-or-existing-branch>` - push to a new branch before submitting a PR

and [k/k
in-tree](https://github.com/kubernetes/kubernetes/tree/master/test/e2e/testing-manifests/storage-csi/hostpath/hostpath)

## Adding support for a new Kubernetes release

1. Add the new release to `k8s_versions` in
https://github.com/kubernetes/test-infra/blob/090dec5dd535d5f61b7ba52e671a810f5fc13dfd/config/jobs/kubernetes-csi/gen-jobs.sh#L25
to enable generating a job for it. Set `experimental_k8s_version`
in
https://github.com/kubernetes/test-infra/blob/090dec5dd535d5f61b7ba52e671a810f5fc13dfd/config/jobs/kubernetes-csi/gen-jobs.sh#L40
to ensure that the new jobs aren't run for PRs unless explicitly
requested. Generate and submit the new jobs.
1. Create a test PR to try out the new job in some repo with `/test
pull-kubernetes-csi-<repo>-<x.y>-on-kubernetes-<x.y>` where x.y
matches the Kubernetes release. Alternatively, run .prow.sh in that
repo locally with `CSI_PROW_KUBERNETES_VERSION=x.y.z`.
1. Optional: update to a [new
release](https://github.com/kubernetes-sigs/kind/tags) of kind with
pre-built images for the new Kubernetes release. This is optional
if the current version of kind is able to build images for the new
Kubernetes release. However, jobs require less resources when they
don't need to build those images from the Kubernetes source code.
This change needs to be tried out in a PR against a component
first, then get submitted against csi-release-tools.
1. Optional: propagate the updated csi-release-tools to all components
with the script from
https://github.com/kubernetes-csi/csi-release-tools/issues/7#issuecomment-707025402
1. Once it is likely to work in all components, unset
`experimental_k8s_version` and submit the updated jobs.
1. Once all sidecars for the new Kubernetes release are released,
either bump the version number of the images in the existing
[csi-driver-host-path
deployments](https://github.com/kubernetes-csi/csi-driver-host-path/tree/master/deploy)
and/or create a new deployment, depending on what Kubernetes
release an updated sidecar is compatible with. If no new deployment
is needed, then add a symlink to document that there intentionally
isn't a separate deployment. This symlink is not needed for Prow
testing because that will use "kubernetes-latest" as fallback.
Update that link when creating a new deployment.
1. Create a new csi-driver-host-path release.
1. Bump `CSI_PROW_DRIVER_VERSION` in prow.sh to that new release and
(eventually) roll that change out to all repos by updating
`release-tools` in them. This is used when testing manually. The
Prow jobs override that value, so also update
`hostpath_driver_version` in
