Where can I find the Mule Galaxy project?

The open-source Mule Galaxy project is still active and can be found here. In response to customer feedback, we have included an enterprise-class service registry with Mule ESB Enterprise subscriptions. The service registry is based on Mule Galaxy and includes features such as service and artifact management, publishing, indexing and discovery of services, governance and lifecycle management, deployment and runtime stability, and more. You can read about all the service registry features here.
