Towards a stable JSON Schema

About this time last year, I hosted a discussion at the API Specification Conference about the future of JSON Schema. The most popular topic of discussion was, when JSON Schema is going to be 'done'. Of course we've heard that question a lot. The question stems from the 'draft' label we put on your releases. The term 'draft' has led to quite a bit of confusion for our community over the years, so let's take a moment to understand where it comes from.
