Akka.Serialization.Hyperion 1.3.8-beta65

Maintenance Release for Akka.NET 1.3** Akka.NET v1.3.8 is a minor patch consisting mostly of bug fixes as well as an upgrade to DotNetty v0.4.8. DotNetty v0.4.8 Upgrade** You can [read the release notes for DotNetty v0.4.8 here](https://github.com/Azure/DotNetty/blob/5eee925b7597c6b07689f25f328966e330ff58f9/RELEASE_NOTES.md) - but here are the major improvements as they pertain to Akka.NET: 1. DotNetty length-frame decoding is now fully-supported on .NET Core on Linux and 2. Socket shutdown code has been improved, which fixes a potential "port exhaustion" issue reported by Akka.Remote users. If you've been affected by either of these issues, we strongly encourage that you upgrade your applications to Akka.NET v1.3.8 as soon as possible. Updates and Additions** 1.
