We (the developers) are not at liberty to disclose our development roadmaps to the public for a variety of reasons, which is why we’re left in the unfortunate position of saying “if only you knew what we know”. Trust me, it’d be a lot easier if I could just tell you what we’re planning!
We’re trying to get better at documentation, and we hope the community can help us bring it up to speed. We’re trying to consolidate all information developers need at https://github.com/justintv/Twitch-API. We’ve been updating it as we add new features, and we also post thread in these forums to announce upcoming changes (when we can), or announce changes right after they occur (when we can’t pre-announce for business reasons).
If you have any suggestions on how we can better communicate changes, or how we can better the documentation, we’d love to hear it!
