Notable changes

Akka 2.6.13 Released | Akka

Note that this release may need your project to upgrade to the latest Scala version to compile (Scala 2.13.4+ or 2.12.13+) because of an issue with the @nowarn annotation #30018. If not compilation may fail with this error:

Akka 2.6.13 Released | Akka

We have already used scala 2.13.4.

        scalaVersion := "2.13.4",

Akka 2.6.14 Released | Akka

It is possible that the Jackson upgrade from 2.10 to 2.11 is not completely source and binary compatible. We have inspected the Jackson changelogs and have not found any obvious issues. If you do use more advanced Jackson features such as custom modules where you interface with more of the Jackson APIs or have third party dependencies depending on Jackson of a different version it is important that you carefully test your application when upgrading.

Rolling upgrades
This release includes a new Akka Cluster Sharding internal message that is used whenever a shard region is terminated (see #30402). If you run a rolling upgrade, you might see deserialization warnings for message RegionStopped in the logs of the oldest node (the one holding the shard coordinator). It’s safe to ignore those warnings during the upgrade.
