>From the build scripts, it looks like we only require version >= 0.9.16
because of a particular bug we found prior to that version. From the
testing we did manage to do, we tried a few different versions (fairly
sure a few versions in 0.9.2x) as well as building from upstream source.
I don't believe we found any breaking changes, API or otherwise in that,
it's been pretty stable it seems.
