v7.1.2

Compare Source

Same as v7.1.1, except compiled against Node 6 instead of Node 8 by accident (e.g had async functions).

v7.1.1

Compare Source

EDIT: had a publish issue here as well where it compiled against Node 8 instead of Node 6 so 7.1.2 will fix this.
Also force publish @babel/runtime and @babel/runtime-corejs2. We need to fix the publishing around that since Lerna doesn't pickup the @babel/helpers changes as there is no "dependency"
