OpenAPI v3.1 #471
Description
Hello there! Thanks for this brilliant tool, it was such a shame to see the go community stuck with OpenAPI v2.0 for so long, but you've rescued everyone nicely.
OpenAPI v3.1 is out, and thankfully it's not as much of a change as v2>v3 was. It finally converges with JSON Schema, so it's entirely compatible (just a few extra keywords like discriminator which do not change the meaning of the OpenAPI document at all).
Here are the changes: https://www.openapis.org/blog/2021/02/16/migrating-from-openapi-3-0-to-3-1-0
Normally I'd say upgrading isn't so hard, because you can grab any old JSON Schema tooling and use that, but the Go JSON Schema tooling is a little out of date: https://json-schema.org/implementations.html#validator-go
This might be a good oppertunity to abstract the v3.0 schema logic into its own code, then tweak it a little to be true JSON Schema Draft 2020-12, release that part as a pure JSON Schema module, then you can deprecate the v3.0 logic in the future. Then JSON Schema has some new validation logic, and you're up to date with a slightly smaller package.
Alternatively you could reach out to the maintainers of those Go JSON Schema packages and see if any of them could be updated easily. Many are driver based so perhaps you could send your tweaked v3.0 logic over to them as Draft 2020-12 support!
