Lagom 1.5.0-RC1 released!

We are happy to announce the availability of Lagom 1.5.0-RC1. This is the first release candidate of Lagom 1.5.0. We expect this to be considerably more stable than the milestone releases, not only in terms of functionality but we are also moving closer to the idea of freezing the APIs.

As with milestones, the primary goal is to get feedback, so please let us know if something isn’t working or you see something that should be improved. If there are changes not well documented in javadocs, scaladocs or our migration guides, please, let us know so that we can improve them before the general availability release.


Upgrades for Play, Akka and Alpakka Kafka

See GitHub for the full list of commits and the issues and pull requests assigned to the 1.5.0-RC1 milestone.

Updating a Lagom project to version 1.5.0-RC1

First, make sure you read the Lagom 1.5 Migration Guide for Scala or Java.

To update an sbt project, change the version of lagom-sbt-plugin in your project/plugins.sbt file.

To update a Maven project, change the lagom.version property in your top-level pom.xml.

After updating, it is recommended to fix any new deprecation warnings you see when compiling or running your services.
