Short version: JSON Schema Draft 2019/09 was published, and OpenAPI v3.1 looks likely to have #1977 included - which brings full JSON Schema Draft 2019/09 support. So when will OpenAPI v3.1 come out?

A while back I wrote an article called Understanding RPC, REST and GraphQL which outlined the "what" in how these various approaches differ. This got a few people thinking I was saying REST was drastically superior in all ways, which is a common conclusion when folks hear me describe REST as a layer of abstractions on top of RPC鈥 More abstractions does not mean definitively "better", sometimes that's going to be overkill, so let's look at when you might want to use which.

This article outlines a list of common misunderstandings about REST, so I thought it would be a nice opportunity to set the record straight on a bunch of them. The article is really just 100% misunderstandings, so lets learn some stuff!
