This is a tracking bug for Change: Ruby 2.5 For more details, see: https://fedoraproject.org//wiki/Changes/Ruby_2.5 Ruby 2.5 is the latest stable version of Ruby. Many new features and improvements are included for the increasingly diverse and expanding demands for Ruby. With this major update from Ruby 2.4 in Fedora 26 to Ruby 2.5 in Fedora 28, Fedora becomes the superior Ruby development platform.
This is implemented, we did mass rebuild of Ruby packages and things mostly work just fine.
This bug appears to have been reported against 'rawhide' during the Fedora 28 development cycle. Changing version to '28'.
