DMPRoadmap
Upgrade Ruby version
Upgrade Ruby from 2.6.3 to 2.7 or 3.x
See the release notes at: https://www.ruby-lang.org/en/
Related to #3103
The big question here is whether or not we should consider upgrading to 3.0 or 3.1.
Seems like Rails 5 is not compatible with Ruby 2.7 according to these sources : https://www.fastruby.io/blog/ruby/rails/versions/compatibility-table.html https://github.com/rails/rails/issues/38426
The official guide says 2.2.2 or newer : https://guides.rubyonrails.org/upgrading_ruby_on_rails.html
I tried switching from Ruby 2.6 to 2.7 on the roadmap code, basic features seems to be working fine, but I guess we can expect some side effects
According to the Ruby website, 2.7 is still maintained (2.7.6 was released in April of this year) https://www.ruby-lang.org/en/downloads/branches/ https://www.ruby-lang.org/en/news/2022/04/12/ruby-2-7-6-released/
Rails 5.2 is not compatible with Ruby 2.7 but Rails 6 is : https://github.com/rails/rails/issues/38426
I suggest that we update to Rails 6 (see #3103) before upgrading to Ruby 3 as Rails 6.1 is compatible.
Plus we wouldn't have to upgrade Ruby when moving to Rails 7
