LGTM!

I wonder if it would hurt to pass both postId and postIds for every call to support both versions without an if statement? Not a big deal either way.

That was something I thought of as well, but I'm not entirely sure of how the backend processes requests (whether it rejects them or ignores them) so I just played it safe. I am thinking of maybe dropping support for 0.18.x in the near future (maybe in v0.6.0, but nothing set in stone) so it might not be a big issue regardless!
