Release 2.0.0 Checklist

We have a new team of maintainers!

Myself (@pboling), @xtagon, @josephpage, @galois17 and a few others, are volunteering their efforts.

We are working on getting a new release out, @ 2.0.0. This is a checklist to make sure we do it in an orderly fashion.

• What is the current minimum Ruby Version requirement of the gem, based on internal code and dependencies?
  • [FIX] Documentation in README
  • [FIX] Ruby req in gemspec
• According to semver, how much of a version bump should the next release be?
  • bumping faraday should make this at least a minor point release.
  • officially dropping support for older Ruby versions might make this a major point release.
