v0.3.7

Changes since v0.3.6

📢 Starting with this release, clusterctl is required to install published components files

Update to the latest released version of clusterctl before to install or upgrade component files, kubectl apply individual yaml files is not supported or suggested. Starting with this release (v0.3.7), clusterctl supports extended variable template substitutions, if you encounter any issues related to templating or environment variables update to the latest version or file an issue.

⚠️ Breaking Changes

• clusterctl: log.Log is now exposed correctly as logr.Logger (#3290) — Impact: Clients using the logr methods should have no impact, other clients should switch to this interface instead of the old delegating logger one which exposed internal bits.
• Use cache tracker to get a client for remote clusters (#3154) — Impact: This PR removed WatchInput.CacheOptions when creating a new watcher on a remote cluster because it would only be respected once. If you need to set custom variables (e.g. scheme or rest mapper) for the cache, they're now inherited from the Manager's passed in when creating the ClusterCacheTracker.

✨ New Features

• Introduce ClusterResourceSet (#3107, #3013) — ClusterResourceSet (CRS) is a new experimental feature built into Cluster API, it can be enabled by supplying --feature-gates="ClusterResourceSet=true" to the manager and webhook deployment flags.
• KubeadmControlPlane: Users should now be able to mutate node registration options (#3324) — Note: If you're modifying NodeRegistrationOptions, make sure to supply the same information both under InitConfiguration and JoinConfiguration.
• KubeadmControlPlane: Users should now be able to disable kube-proxy management in KCP using controlplane.cluster.x-k8s.io/skip-kube-proxy annotation (#3319)

• KubeadmControlPlane: Support adopting existing Machines (#2489)
