0.9 changed the way that annotation names were treated and validated etc. So code that works with 0.8 doesn't necessarily work with 0.9+.

So I think we should support 0.9 and above only.

Seems the CIs aren't happy though :(

Failures were just not having the fOLD files, fixed. I'll go ahead and merge. We should backport this and release a 0.2.1. I'll actually wait to do that until the doc buliding is fixed, hopefully tomorrow! Then we can see deployment of 0.2.1 docs and 0.3.dev0 docs, hopefully.
