How to make a release

These are the instructions on how to make a release of the Helm charts dask and daskhub maintained in this repository.

Background

The packaged charts are published using a GitHub Pages based website also maintained in this repository under the gh-pages branch. It is available at https://helm.dask.org in a human readable way, where helm inspects https://helm.dask.org/index.yaml. For details about this, see the gh-pages branch's readme.

We currently do releases of both the dask and daskhub at the same time, and aren't maintaining a changelog for either.

The Helm charts dask-gateway and dask-kubernetes-operator also published via this repository's GitHub Pages website are maintained at https://github.com/dask/dask-gateway/ and https://github.com/dask/dask-kubernetes/ respectively with independent release processes.

Checkout main and make sure it is up to date.

git checkout main
git fetch origin main
git reset --hard origin/main # warning: a destructive action

Decide on a version.

We are using version tags like 2025.6.0 of the format year.month.x where the month number must not include a leading zero and the last number should either be zero or incremented if more than one release is made in a month.
Use tbump to push a git tag.
```
pip install tbump

# tbump will first clarify what it will do and await your confirmation
tbump 2025.6.0
```
Following this, the CI system will build and publish a release, where the tool chartpress will update the Chart.yaml file's version based on the git tag.
