__Akka.TestKit.Xunit Changes__
Due to breaking API change in Xunit 2.5.0, updating to Akka.NET 1.5.9 might break your unit tests. Some of the breaking change that we've noticed are:
`AkkaEqualException` constructor has been changed due to changes in Xunit API. If you're using this class, please use the `AkkaEqualException.ForMismatchedValues()` static method instead of using the constructor.
Testing for exception types by calling async code inside a sync delegate will not unwrap the `AggregateException` thrown. Either use async all the way or manually unwrap the exception.
Xunit `Asset.Equal()` does not automatically check for collection item equality anymore, that means doing `Assert.Equal()` between two dictionary or list would not work anymore.
Some Xunit classes have been changed from public to private. If you're using these classes, you will need to refactor your code.
__FsCheck.Xunit:__ Xunit Roslyn analyzer has become a bit too overzealous and insists that all unit test method can only return either void or Task and will raise a compilation error if you tried to return anything else. If you're using `FsCheck.Xunit`, you will need to use a pragma to disable this check: `#pragma warning disable xUnit1028`.
