Akka 1.4.25
Akka.NET is a port of the popular Java/Scala framework Akka to .NET
No packages depend on Akka.
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](https://github.com/akkadotnet/akka.net/issues/5154)
[Akka.Actor: need to enforce `stdout-loglevel = off` all the way through ActorSystem lifecycle](https://github.com/akkadotnet/akka.net/issues/5246)
[Akka.Actor: `Ask` should push unhandled answers into deadletter](https://github.com/akkadotnet/akka.net/pull/5259)
[Akka.Routing: Make Router.Route` virtual](https://github.com/akkadotnet/akka.net/pull/5238)
[Akka.Actor: Improve performance on `IActorRef.Child` API](https://github.com/akkadotnet/akka.net/pull/5242) - _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 `ActorSelection`s or remote messages) so this change should be safe.
[Akka.Actor: `IsNobody` throws NRE](https://github.com/akkadotnet/akka.net/issues/5213)
[Akka.Cluster.Tools: singleton fix cleanup of overdue _removed members](https://github.com/akkadotnet/akka.net/pull/5229)
[Akka.DistributedData: ddata exclude `Exiting` members in Read/Write `MajorityPlus`](https://github.com/akkadotnet/akka.net/pull/5227)
Performance Improvements**
Using our standard `RemotePingPong` benchmark, the difference between v1.4.24 and v1.4.24 is significant:
_v1.4.24_
```
OSVersion: Microsoft Windows NT 6.2.9200.0
ProcessorCount: 16
ClockSpeed: 0 MHZ
Actor Count: 32

```
This represents a 24% overall throughput improvement in Akka.Remote across the board. We have additional PRs staged that should get aggregate performance improvements above 40% for Akka.Remote over v1.4.24 but they didn't make it into the Akka.NET v1.4.25 release.
