Big changes related to the Warden project – it has been totally rewritten to the new .NET Core in order to support cross-platform capabilities (at least in a future). The functionality per se (including API) didn’t change, yet from now on you can use Warden with the new DNX runtime. If you’re interested in the migration process, a current status of this update (including the supported parts of the project) and what are the next goals – take a look at the whole post.
