the most visible change of this release is the addition of the new client stack and its 17 web providers
that aim at offering an alternative to the aspnet-contrib providers
(additional services will be added in future versions of OpenIddict)
Last year, Mike Rousos posted a great post about token authentication on the .NET blog and demonstrated how you could leverage ASP.NET Core Identity and OpenIddict to create your own tokens in a completely standard way.
