Coverage increased (+0.3%) to 90.541% when pulling 8650c1d on nsmith5:update-dataframes into 9f5fbe9 on JuliaWeb:master.

Probably a good idea to tag a new release after this. 0.2.x makes sense to me because the API hasn't changed at all just deprecation of older Julia versions.

[randyzwitch]

LGTM. I'll tag a new version.

[nsmith5]

I deleted and created the release again to trigger attobot. Hopefully our PR on METADATA will succeed this time..
