+
+## v10.0.1
+- Fixed a bug that could cause a failure to recognize commands when using a large number of recipients.
+
+## v10.0.0

+
+## v9.1.0
+
+- Added a ResponseException event handler to the ISessionContext to enable external logging of exceptions.
+
+## v9.0.3
+
+- Fixed a bug with the session not closing when the cancellation token was cancelled.
+
+## v9.0.2
+
+- Fixed a performance issue whereby the server would block incoming connections whilst another connection was upgrading to SSL.
+
+## v9.0.0
+
+- Breaking API change by removing the Certificate from the server options and adding it to the endpoint.
+
+## v8
+
+- Version 8 contains substantial refactoring to take advantage of [System.IO.Pipelines](https://www.nuget.org/packages/System.IO.Pipelines/) in an effort to improve throughput performance and reduce memory allocations. 
+- In addition to this there are also changes to make service resolution easier via Dependency Injection through utilizing the [IServiceProvider](https://docs.microsoft.com/en-us/dotnet/api/system.iserviceprovider) interface.
