+If you made very big changes to the chart, you'll want to test whether the chart still works before releasing the new version. To do so, create an MR in the stackspin/stackspin repository, change `flux2/core/base/sources/nextcloud-helmrepository.yaml` to track the `unstable` helm repository, instead of `stable`, and change `flux2/apps/nextcloud/release.yaml` to this MRs chart version.
