 ### New Policy for Controller Registrations ([gardener/gardener#2896](https://github.com/gardener/gardener/pull/2896))
 
 A while ago, we added support for different policies in `ControllerRegistrations` which determine under which circumstances the deployments of registration controllers happen in affected seed clusters. If you specify the new policy `AlwaysExceptNoShoots`, the respective extension controller will be deployed to all seed cluster hosting at least one shoot cluster. After all shoot clusters from a seed are gone, the extension deployment will be deleted again.
-A full list of supported policies can be found at [Registering Extension Controllers](https://github.com/gardener/gardener/blob/master/docs/extensions/controllerregistration.md#deployment-configuration-options).

-As organizations embrace Kubernetes for managing containerized applications at scale, the underlying infrastructure costs, particularly for compute resources, become a critical factor. Gardener, the open-source Kubernetes management platform, empowers organizations like SAP, STACKIT, T-Systems, and others (see [adopters](https://gardener.cloud/adopter)) to operate tens of thousands of Kubernetes clusters efficiently across diverse environments. Gardener's role as a core technology in initiatives like [NeoNephos](https://neonephos.org/projects), aimed at advancing digital autonomy in Europe (see [KubeCon London 2025 Keynote](https://www.youtube.com/watch?v=85MDID9Ju04&t=621s) and [press announcement](https://neonephos.org/2025/03/31/the-linux-foundation-announces-the-launch-of-neonephos-to-advance-digital-autonomy-in-europe)), further underscores the need for cost-effective and sustainable operations.

 At the heart of Gardener's architecture is the concept of "Kubeception" (see [readme](https://github.com/gardener/gardener?tab=readme-ov-file#gardener) and [architecture](https://github.com/gardener/gardener/blob/master/docs/concepts/architecture.md)): Gardener runs *on* Kubernetes (called a **runtime cluster**), facilitates access *through* a self-managed node-less Kubernetes cluster (called the **garden cluster**), manages Kubernetes control planes as pods *within* self-managed Kubernetes clusters that provide high scalability to Gardener (called **seed clusters**), and *provisions* end-user Kubernetes clusters (called **shoot clusters**). Therefore, optimizing Gardener's own Kubernetes-related resource consumption directly translates into cost savings across all these layers, benefiting both Gardener service providers and the end-users consuming the managed clusters.
