This is a new patch release for the Helm chart of actions-runner-controller, which includes a fix, #843, for the issue that CRDs included in the chart was okay for a clean install but not okay for an upgrade. Note that helm upgrade doesn't upgrade CRDs, but you may still used the CRDs included in the chart as the source for kubectl apply.
A lot of thanks goes to @tyrken who spotted the cause and contributed the patch!
