A v1.35.0 release has been made, but I think it incorrectly dropped support for Ruby 1.9.3 (https://github.com/fog/fog/issues/3711#issuecomment-149810899). If that's resolved then we may be able to update to that first.

1.36.0 has been released which should fix this, so I've filed #12494 to pick this up. I'll leave this ticket pointing at 2.0.0 as it's still expected to drop 1.9 support there.
