- File 0001-Drop-Ruby-2.5-Support.patch added
- File 0002-Update-TargetRubyVersion-of-RuboCop-to-2.5.patch added
The attached patches drop Ruby 2.4 support.
As Marius wrote, Rails 6 requires Ruby 2.5 or later. We have to migrate to Rails 6 in Redmine 5.0 because the support for Rails 5.2 which we are currently using will end when Rails 7.0 (the next version of Rails) is released.
And Ruby 2.4 has already become EOL in March 2020.
