Is sendgrid-ruby still ruby 2.2. compatible?

The gem has a single, recently introduced, safe navigation operator that breaks ruby 2.2.

Hello @platphorm,

The lowest version of ruby we support today is 2.4.

With best regards,

Elmer

Good to know, thanks @thinkingserious The gemspec does have: spec.required_ruby_version = '>= 2.2'
