Adopting Akka Persistence JDBC 4.0

No data migration is needed when updating from 3.5.3.

This version requires Akka 2.6.4 or later.

The groupdId changed in this release. It’s now being published under the com.lightbend.akka groupd ID. Make sure to remove any dependency on the previous 3.5.x artifacts that were being published under com.github.dnvriend. There is a runtime check that will throw an exception when loading the plugin if it detects that both artifacts are in the classpath.

There are a few source and binary incompatible changes if you have implemented custom DAOs. The compiler will detect these changes when you recompile.

There is no major behavior change in this release except for one minor bug fix. Previously, when querying using currentEventsByPersistenceId, the offset field in the returned EventEnvelope was set to the event sequence number. This was not the intended behavior. The offset is now being correctly filled with the event offset. If you need to have access to the event sequence number, you should access it through EventEnvelope.sequenceNr field.
