- 🪓 [USER] The VPA version is updated to 1.3.0. Upstream VPA 1.3.0 does no longer serve API version

NamespacedCloudProfile.spec.limits.maxNodesTotal can now also be used to override the limit defined in the parent CloudProfile with an increased value. Increasing requires additional permissions granted by the custom verb raise-spec-limits. #11796 - ✨ [OPERATOR]
gardener-operator automatically adds the networking.resources.gardener.cloud/to-virtual-garden-kube-apiserver-tcp-443: allowed label to the gardenlet deployment in case it is deployed to the garden runtime cluster. Thus, it is not required anymore to configure this label in the Gardenlet resource. #11855

class field in the generic extension controller was removed. Please use the new field classes instead. #11764 - ✨ [OPERATOR] The feature gate

- ✨ [USER] If the Gardener operator has defined a control plane wildcard certificate, the
.status.advertisedAddresses of the Shoot contain an entry with an endpoint secured by this certificate. Note that this endpoint is specific to the seed cluster the Shoot is scheduled to. Read all about it in this document. #11612 - ✨ [OPERATOR] The
injectGardenKubeconfig field is defaulted to true for extensions responsible for Worker resources when registered via the operator.gardener.cloud/v1alpha1.Extension API. #11658

- 🪓 [OPERATOR] ⚠️ Gardener does no longer support garden, seed, or shoot clusters with Kubernetes versions <= 1.26. Make sure to upgrade all existing clusters before upgrading to this Gardener version. #10664
- 🪓 [USER] All
Seeds are now automatically labeled with name.seed.gardener.cloud/<name>=true (⚠ no longer seed.gardener.cloud/<name>=true) where <name> is their own name, and (if applicable) the name of their parent seed in case they are managed seeds. This label can be used as selector for requests. #11479 - ✨ [OPERATOR]
gardener-operator now waits for required Extensions to get ready early in the reconcile flow. It addresses use-cases where extensions run mutating webhooks in the garden runtime cluster that must be present when Garden components are deployed. #11523
