Lagom 1.5.1 and 1.4.12 Released: Akka Service Discovery integration

The Lagom team has released the versions 1.5.1 and 1.4.12. For a list of the specific changes in Lagom 1.5.1, see the change log (1.5.1), and for a list of changes in Lagom 1.4.12 see the change log (1.4.12).


These two releases bring into Lagom a new Service Locator implementation, based on Akka’s Service Discovery. This component was previously released as an apart library, lagom-akka-discovery-service-locator, and intended to be a replacement for the Service Locator previously offered by Lightbend Orchestration.

In order to allow a smoother transition for Lagom 1.4 users, we decided to include it in 1.4.12 and 1.5.1. So users can choose to first migrate their Lagom 1.4 application to Akka Service Discovery and then to Lagom 1.5. Of course, this is not a required step. It is also possible to migrate directly from Lagom 1.4 and Lightbend Orchestration to Lagom 1.5 and Akka Service Discovery.
