[hsbt]

Ruby 2.0 is EOL at 2020.

[marcandre]

@hsbt The current gemspec states required_ruby_version >= '2.0' (after #415) and travis tests run on Ruby 2.0.

I believe the actual reason for closing this issue is that json-1.x is no longer supported, right?

[hsbt]

Yes. I have no motivation about that.
