[gardener/gardener]

⚠️ Breaking Changes

• [DEVELOPER] The following mapper funcs from the extension library no longer accept a context.Context arg - ClusterToContainerResourceMapper, ClusterToControlPlaneMapper, ClusterToDNSRecordMapper, ClusterToExtensionMapper, ClusterToInfrastructureMapper, ClusterToNetworkMapper, ClusterToWorkerMapper and ClusterToObjectMapper. The context.Context arg was redundant and not used. by @​acumino #8321
• [USER] Deprecated annotation alpha.featuregates.shoot.gardener.cloud/node-local-dns is removed. Use field .spec.systemComponents.nodeLocalDNS.enabled in Shoot instead. Switching on node-local-dns via shoot specification will roll the nodes even if node-local-dns was enabled beforehand via annotation. by @​acumino #8364
• [USER] Deprecated annotation alpha.featuregates.shoot.gardener.cloud/node-local-dns-force-tcp-to-{cluster-dns, upstream-dns} is removed. Use field .spec.systemComponents.nodeLocalDNS.{forceTCPToClusterDNS, forceTCPToUpstreamDNS} in Shoot instead. by @​acumino #8364

🐛 Bug Fixes

• [OPERATOR] operator now deletes ManagedResources deployed to the virtual-garden before deleting virtual-garden-kube-apiserver. by @​oliver-goetz #8368
• [OPERATOR] A bug is fixed that prevented scraping the metrics of etcd in the shoot control plane. by @​istvanballok #8371
