fluxcd/flux2 v0.27.0 on GitHub

Highlights

Flux v0.27.0 comes with new features and improvements. Users are encouraged to upgrade for the best experience.

Flux custom resources require their names to follow the DNS label standard as defined in RFC 1123. The metadata.name can only contain lowercase alphanumeric characters or - and must contain at most 63 characters.
This version introduces a breaking change to the Helm uninstall behavior, as the --wait flag is now enabled by default. Resulting in helm-controller to wait for resources to be deleted while uninstalling a release. Disabling this behavior is possible by setting spec.uninstall.disableWait: true in HelmRelease manifests.

Add support to notification-controller for sending events to Grafana annotations API.
Allow selecting event sources based on labels using the Alert API spec.eventSources[].matchLabels field.
Add support to kustomize-controller for making the Kubernetes Secrets and ConfigMaps referenced in postBuild.substituteFrom optional.
Allow dot-prefixed paths to be used for bootstrap e.g. flux bootstrap --path=".flux/clusters/my-cluster".
All Flux controllers and libraries are now tested by Google's continuous fuzzing for open source software.
