Farewell from Waffle

Timeline and migrating to GitHub Projects
Waffle will continue to be available until May 16th, 2019 at which point it will become completely unavailable. We have worked closely with the wonderful team at GitHub to create a migration path out of Waffle and into GitHub Projects. This will take your Waffle board and create a GitHub Project with the same columns and cards as you have in Waffle.
