4.0.0 - At last

I believe it's finally time to ship a new stable version, after shipping 17 betas of the 4.0.0 branch.

4.0 contains lots of breaking changes to the API, but also contains support for modern .net features and a lot of cleanups in terms of the webauthn implementation.

We wanted to include some refreshments to our MDS implementation and use of cache -- but we're punting it to a future release.
