Redmine

Did you test current trunk ?
It passes tests with ruby 1.8.7 + rails 2.1. Please report any compatibility problem.

Well. I have redmine 0.7.3 on ruby 1.8.7 and it works ok with patched rails 2.0.2.
There is only one thing changed:
Change truncate in actionpack-2.0.2/lib/action_view/helpers/text_helper.rb to:

      def truncate(text, length = 30, truncate_string = "...")
        if text.nil? then return end
        l = length - truncate_string.length
        if $KCODE == "NONE" 
          text.length > length ? text[0...l] + truncate_string : text
        else
          chars = text.split(//)
          chars.length > length ? chars[0...l].join + truncate_string : text
        end
      end

That fix can be found somewhere here (issues or board ;)
