text: Title: Feature Request: Interact with new GH projects as for classic ones
  Body: The way github3 allows to interact with classic projects is just great: unfortunately those will be discontinued this August, i.e. in a month.
  It would be very useful to have a way to interact with new GH projects, which are now the standard, ideally with an API which is as similar as possible to the current one for classic projects.
  I apologise in advance if this feature already exists and I missed it.
  
  Thanks a lot for considering this upgrade of github3!
