Breaking Changes

Since version 7.2, in an effort to improve the performance on the publishing side, we have tasked the .NET thread pool with handling message publishing. However, because tasks in the thread pool are not guaranteed to be executed in order, and because ensuring linear publishing makes sense in certain use cases, we will revert to linear publishing starting with this version. At the same time, we are introducing a new option, EnablePublishParallelSend, to allow users to enable parallel message sending.

• Upgrade reference nuget packages.
