Supported Ruby Versions

This library aims to support and is tested against the following Ruby implementations:

  • Ruby 1.9.3
  • Ruby 2.0.0
  • Ruby 2.1
  • Ruby 2.2
  • JRuby 1.7
  • JRuby

If something doesn't work on one of these interpreters, it should be considered a bug.

This library may inadvertently work (or seem to work) on other Ruby implementations, however support will only be provided for the versions listed above.

If you would like this library to support another Ruby version, you may volunteer to be a maintainer. Being a maintainer entails making sure all tests run and pass on that implementation. When something breaks on your implementation, you will be personally responsible for providing patches in a timely fashion. If critical issues for a particular implementation exist at the time of a major release, support for that Ruby version may be dropped.
