-
-This release introduces the new [**Akka.Discovery.Dns** module](https://github.com/akkadotnet/Akka.Management/tree/dev/src/discovery/dns/Akka.Discovery.Dns), providing native DNS-based service discovery for Akka.NET clusters! This powerful addition enables:

-* **DNS-based Service Discovery**: Automatically discover Akka.NET nodes using DNS SRV and A records
-* **Cloud-Native Integration**: Seamlessly integrate with Kubernetes DNS, Azure DNS, AWS Route 53, and other DNS providers
-* **Zero-Configuration Discovery**: Works out-of-the-box with standard DNS infrastructure
-* **Cluster Bootstrap Support**: Full integration with Akka.Management cluster bootstrap for automatic cluster formation
-
-The DNS discovery mechanism is ideal for containerized environments, cloud deployments, and any infrastructure with DNS-based service registration.
