I'm still fairly new to Rails. I've been training on Rails application development for the last two months with a basic text editor. I'm starting to get comfortable and I'm ready to start using RubyMine full time. At work, the Rails server is on a fairly old version of Rails and there's no plans to upgrade it (Rails: 2.02, Gems 1.36, Ruby: 1.86). I've matched my work development system to those versions.
I know there were massive changes in Rails after 2.0.x, like 1600 patches in 2.1 including the scaffold generator being completely changed to a restful scafold generator (from what I read). Just out of curiousity, is there anything I should be aware of or any issues that might come up using RubyMine against such an old version like 2.0.2?
