Hi @U70QFSCG2, my understanding is that Apex is currently being developed under the umbrella of the site repo to support faster iteration whilst it's all work-in-progress - see https://github.com/juxt/site/tree/master/src/juxt/apex - I don't think there is a well-formed plan to copy the changes back upstream to the standalone repo yet, and I expect that will only happen once site itself has stabilised. Out of interest, is it the OpenAPI aspects in particular that you are interested in? Or something else?

Thanks @U899JBRPF! Yea, OpenAPI is exactly what I'm interested in
