Migration Guide 2.9.x to 2.10.x

Support for slf4j 1.7.x and logback 1.2.x removed

This is the first release that only supports slf4j 2.0.x and logback 1.5.x.

Changes to Java Flight Recorder (JFR)

The config akka.java-flight-recorder.enabled was removed. Instead, the JFR interactions are recorded directly.

Please use the jvm native flags to take advantage of the JFR recorded events.

Remove dependency to scala-java8-compat

The transitive dependency on scala-java8-compat has been removed.

Deprecation of akka.actor.typed.scaladsl.LoggerOps

All helper methods like LoggerOps.info2 can be replaced by using the underlying org.slf4j.Logger apis.

Deprecation of Multi-DC Cluster

Use Akka Distributed Cluster and Akka Edge instead.
