Renku ``0.39.1`` fixes bugs in the Helm chart introduced by ``0.39.0``.


Internal Changes
~~~~~~~~~~~~~~~~

This introduces changes in the templates and values file of the Helm chart from 0.39.0 that were causing the Helm upgrade
operation to fail.

------

Renku ``0.39.0`` moves all renku component Helm charts to one single chart that now resides in this repository.

After initial testing we have noticed a bug in this version of the Helm chart. If you have already deployed this version simply
upgrading to ``0.39.1`` will fix things. If you have not yet deployed this version then skip it and go straight to ``0.39.1``.
The reason for the bug is that we replaced the ``spec.selector.matchLabels`` field of two important deployments in the Gateway
because of this the two components do not upgrade and the whole Helm upgrade operation fails.

Also, with the next releases we will adopt a specific way of versioning the helm chart. Namely:

- Patch changes (i.e. ``0.50.1`` -> ``0.50.2``) indicate that there are NO changes in the Helm chart and that
only application level bug fixes are present in the new release.
- Minor version changes (i.e. ``0.50.2`` -> ``0.51.0``) indicate that there are NO changes in the Helm chart and that
only application level new features and/or application level breaking changes are present.
- Major version changes (i.e. ``0.50.0`` -> ``1.0.0``) will be reserved for changes in the Helm chart, either when the
values file changes or when the Helm templates change.

Please note that this is a breaking change to the values file and it requires three minor edits to the following fields:

- ``graph.jena.*`` moved to ``jena.*``
- ``notebooks.amalthea.*`` moved to ``amalthea.*``
- ``notebooks.dlf-chart.*`` moved to ``dlf-chart.*``

For more details please refer to the explanation in ``helm-chart/values.yaml.changelog.md``.

Internal Changes
~~~~~~~~~~~~~~~~

There are now no more separate Helm charts for the core, notebooks, graph, UI and gateway components. All the Helm
templates have been moved into the main Renku Helm chart in this repository.

------

Renku ``0.38.0`` improves the Knowledge Graph API, with a new Project Creation functionality and a Project Update enhancement.
There is also a new version of the core service with multiple bug fixes and a few new features.

------

Renku ``0.37.0`` introduces a new feature to pause sessions and later resume them exactly where you left off. All of your work in progress, including files, data, and environment changes not saved to git, are resumed right as you left them.

This feature replaces RenkuLab's branch-based auto-save mechanism. Most users do not have to do anything to transition from auto-saves to persistent sessions. However, if your last session went into an auto-save, you can still retrieve that work by using Start with Options and selecting your most recent auto-save branch. If your project contains auto-save branches that you do not need anymore, you can safely delete them.
