Akka.Cluster 0.7.1-pre1412132130

__Brand New F# API__. The entire F# API has been updated to give it a more native F# feel while still holding true to the Erlang / Scala conventions used in actor systems. [Read more about the F# API changes](https://github.com/akkadotnet/akka.net/pull/526). __Multi-Node TestKit (Alpha)__. Not available yet as a NuGet package, but the first pass at the Akka.Remote.TestKit is now available from source, which allow you to test your actor systems running on multiple machines or processes. A multi-node test looks like this public class InitialHeartbeatMultiNode1 : InitialHeartbeatSpec { } public class InitialHeartbeatMultiNode2 : InitialHeartbeatSpec { } public class InitialHeartbeatMultiNode3 : InitialHeartbeatSpec { } public abstract class InitialHeartbeatSpec : MultiNodeClusterSpec The MultiNodeTestRunner looks at this, works out that it needs to create 3 processes to run 3 nodes for the test. It executes NodeTestRunner in each process to do this passing parameters on the command line. [Read more about the multi-node testkit here](https://github.com/akkadotnet/akka.net/pull/497). __Breaking Change to the internal api: The `Next` property on `IAtomicCounter<T>` has been changed into the function `Next()`__ This was done as it had side effects, i.e. the value was increased when the getter was called. This makes it very hard to debug as the debugger kept calling the property and causing the value to be increased. __Akka.Serilog__ `SerilogLogMessageFormatter` has been moved to the namespace `Akka.Logger.Serilog` (it used to be in `Akka.Serilog.Event.Serilog`). Update your `using` statements from `using Akka.Serilog.Event.Serilog;` to `using Akka.Logger.Serilog;`. __Breaking Change to the internal api: Changed signatures in the abstract class `SupervisorStrategy`__. The following methods has new signatures: `HandleFailure`, `ProcessFailure`. If you've inherited from `SupervisorStrategy`, `OneForOneStrategy` or `AllForOneStrategy` and overriden the aforementioned methods you need to update their signatures. __TestProbe can be implicitly casted to ActorRef__. New feature. Tests requring the `ActorRef` of a `TestProbe` can now be simplified: ``` C# var probe = CreateTestProbe(); var sut = ActorOf<GreeterActor>(); sut.Tell("Akka", probe); // previously probe.Ref was required probe.ExpectMsg("Hi Akka!"); ``` __Bugfix for ConsistentHashableEvenlope__. When using `ConsistentHashableEvenlope` in conjunction with `ConsistentHashRouter`s, `ConsistentHashableEvenlope` now correctly extracts its inner message instead of sending the entire `ConsistentHashableEvenlope` directly to the intended routee. __Akka.Cluster group routers now work as expected__. New update of Akka.Cluster - group routers now work as expected on cluster deployments. Still working on pool routers.
