Update Gemfile? It's not been touched for over a year. #1234
Description
Asciidoctor just had a major version update.
The latest time the gemfile was touched was on 31th of January 2018, so that's more than a year ago, maybe somebody should look at it again? See: https://github.com/progit/progit2/blob/master/Gemfile
