Redmine

Support for Redmine 4.2 will end when the next major version (probably Redmine 6.0) is released.

Some Gems such as Nokogiri and SQLite have already discontinued support for Ruby 2.7.

I think it is fine to end support for Ruby 2.7 in Redmine 6.0.

Dropped Ruby 2.7 support in r22648.

I will set the TargetRailsVersion of RuboCop to 3.0 after fixing some RuboCop offenses regarding the update to Ruby 3.0.

I set TargetRubyVersion of RuboCop to 3.0 in r22654 after fixing the following offenses.

Due to the update to Rails 7.2.0 in r22960, the trunk no longer supports Ruby 3.0.
Rails 7.2.0 requires Ruby 3.1.0 or later.

I changed the required Ruby version to 3.1 or higher in r22971, and incorporated the new features of Ruby 3.1 in r22972 and r22973.

I am closing this issue.
