You can see the full set of changes for Helios 2.1.3 here.

2.1.2 Jul 14 2016

• Made DNS resolution configurable - can target IPV4 / IPV6 or any other AddressFamily.
• Caught ObjectDisposedExceptions that are thrown on shutdown so they are no longer logged.

2.1.1 May 27 2016

• Fixed issue with AbstractDerivedByteBuf where calling Retain would return the original underlying buffer and not the derived buffer.
• Made configuration warnings in ServerBootstrap less cryptic.

2.1.0 May 16 2016

• Added support for batch writes

Net performance impact of above changes as reported by build server:

2.0.2 May 6 2016

• Added DNS support to ServerBootstrap so hostnames can be bound.

2.0.1 May 6 2016

• Added MessageToMessageDecoder<T> base class to Helios.Codecs

2.0 May 3 2016

Major performance and stability rewrite of Helios, including breaking API changes.

The existing API has been left intact, but marked as Obsolete. Going forward please use the IChannel APIs provided inside the Helios.Channels namespace. They are virtually identical to the equivalent DotNetty APIs, although with some minor differences as a result of existing code and styles within Helios itself.

1.4.2 Dec 12 2015

Bugfixed - fixed an issue with NoOpDecoder where it wouldn't properly drain incoming IByteBuffer instances.

1.4.1 Jul 07 2015

Bugfix - we no longer throw exceptions upon shutting down TCP reactors.

1.4.0 Apr 01 2015

Major update to Helios designed to help support Akka.NET v1.

• Added Mono support to all outbound clients. All benchmarks have been run on Mono as well as the full build suite.
• Fixed data loss issued caused during periods of high-speed writes. This has been resolved.
• Added stubs for tracing and monitoring.
• Integrated Helios.DedicatedThreadPool for a massive performance boost on the DedicatedThreadFiber, used by default on most socket clients.

1.3.6 Feb 09 2015

• Minor bug fixes for concurrent exceptions
