alt Hacker NewsAwesome, feel free to start a thread in #integrations in chat.zulip.org! We'd be happy to chat about some of the things that will make your life easier to do carefully when writing a new client.
The main thing regards our double-entry API changelog system. Basically, the API documentation for individual endpoints, say https://zulip.com/api/get-user, natively cover for each endpoint all the changes relevant for that endpoint from https://zulip.com/api/changelog... and how to write nice code using feature level checks to support all server versions.
That sounds great! I literally just wrote the initial skeleton last night so there's lots of work to do so any help is greatly appreciated! I'm hoping to have something somewhat usable by the end of the month.
