+Akka.NET v1.5.29 introduced an interface change on the `IScheduler` that unfortunately caused a lot of other plugins to break due to API compatibility issues. v1.5.30 rolls back that change but still fixes the underlying bug in Akka.Persistence's handling and serialziation of timestamps without any interface changes. v1.5.29 will be deprecated from NuGet.
