Dear maintainer, meanwhile there is a new upstream version 3.0.5 which fixes some warning on Ruby 2.7.
I updates my personal packages at http://apt.klaumikli/testing today. Tell me if I can help to get the new version into Debian. Klaumi ----------- Klaus-Michael Klingsporn phone: +49-30-9445363 mail: klaumi...@gmx.de web: www.klaumikli.de
