This is still requiring quite an old version of Faraday, which is forcing me to use older versions of other gems in my project.

Duplicate of #45.

This is open source software, consider submitting a PR next time instead of asking others to make a reasonably straightforward change.

1.14.0 is up on RubyGems.

Thank you - much appreciated. And yes you're right - it was a bit lazy of me.
