2.0 release to rubygems

[synth]

Thank you for this gem. I would like to include this in an engine/gem I am building. As an engine/gem, dependencies must be specified in .gemspec file. To my knowledge, there is no way to specify a git/github reference to gemspec spec.add_dependency. As such, in order to use version 2.0 of this gem in an engine/gem, we would need this version published to rubygems. Thanks!
