Akka.NET v1.4.25

1.4.25 September 08 2021

Maintenance Release for Akka.NET 1.4 Akka.NET v1.4.25 includes some significant performance improvements for Akka.Remote and a number of important bug fixes and improvements.

Bug Fixes and Improvements

• Akka.IO.Tcp: connecting to an unreachable DnsEndpoint never times out
• Akka.Actor: need to enforce stdout-loglevel = off all the way through ActorSystem lifecycle
• Akka.Actor: Ask should push unhandled answers into deadletter
• Akka.Routing: Make Router.Route` virtual
• Akka.Actor: Improve performance on IActorRef.Child API - signficantly improves performance of many Akka.NET functions, but includes a public API change on IActorRef that is source compatible but not necessarily binary-compatible. IActorRef GetChild(System.Collections.Generic.IEnumerable<string> name) is now IActorRef GetChild(System.Collections.Generic.IReadOnlyList<string> name). This API is almost never called directly by user code (it's almost always called via the internals of the ActorSystem when resolving ActorSelections or remote messages) so this change should be safe.
• Akka.Actor: IsNobody throws NRE
• Akka.Cluster.Tools: singleton fix cleanup of overdue _removed members
• Akka.DistributedData: ddata exclude Exiting members in Read/Write MajorityPlus

Performance Improvements Using our standard RemotePingPong benchmark, the difference between v1.4.24 and v1.4.25 is significant:
