4.0.0 - Major Release

This is a major release produced as a result of a lot of hard work from many contributors, in all areas, including our own build and release process itself - which will continue to increment on, lot's of bug fixes and optimisations, and we now also run on .NET Core!

Please bear with us as we continue to evolve our release automation to take care of... these release notes right here! #1493

Hopefully we will come back to these release notes and update them at some stage in the near future.
