1.5.22 June 4th 2024

Akka.NET v1.5.22 is a patch release for Akka.NET with a few bug fixes and logging improvement.

• Streams: Bump Reactive.Streams to 1.0.4
• Remote: Bump DotNetty.Handlers to 0.7.6
• Core: Resolve CVE-2018-8292 for Akka.Streams and Akka.Remote
• Core: Expose BusLogging EventStream as public API
• Remote: Add cross-platform support to the exception serializer

On Resolving CVE-2018-8292

In order to resolve this CVE, we had to update DotNetty.Handlers to the latest version and unfortunately, this comes with about 10% network throughput performance hit. We are looking into possible replacement for DotNetty to improve this performance lost in the future (see #7225 for updates).

Akka.Cluster.Sharding.RepairTool
In addition to the work done on Akka.NET itself, we've also created a separate tool for cleaning up any left-over data in the event of an Akka.Cluster.Sharding cluster running with akka.cluster.sharding.state-store-mode=persistence was terminated abruptly before it had a chance to cleanup.

We've added documentation to the Akka.NET website that explains how to use this tool here: https://getakka.net/articles/clustering/cluster-sharding.html#cleaning-up-akkapersistence-shard-state

And the tool itself has documentation here: https://github.com/petabridge/Akka.Cluster.Sharding.RepairTool
