Draft 7 support is coming soon. By almost I mean that it needs to implement dependencies (which I plan to sort out before this goes to vote) and it didn't go through complete regression pack which should happen before the first RC. Draft 7 is pretty much just "if" so it should be supported as well as it's pretty similar to dependencies. I will see about other drafts if they could make it to 8.5 but the plan to support eventually all. I will make it a bit clearer in the RFC. Technically this is more library implementation thing but as it's bundled it should be properly noted in the RFC as well. > > I think your RFC needs to address all these versions and how you plan to > address compatibility issues between them all. > > All drafts except 4 require $schema to be there so it's the way how to currently select the version. The future scope actually lists the default draft for schemas without $schema so it could be selected by users. We could maybe look into some auto-identification in the future but again it would be the future scope. I will add some note about it to the RFC.
