Hi, just wondering: the intro course to Ruby on Rails uses version 5, but some other course use Rails 4.x Can I still benefit from those courses or are they outdated?

36,441 PointsThat depends. Treehouse has a few courses based on Rails 3, another series in Rails 4 and the new ones use Rails 5. Since, as a developer, you will most likely work with legacy code, it would be beneficial to know differences between these three versions.
From experience I can tell you that 90% of the projects you encounter will use Rails 4. Rails 3 is rare, unless the app wasn't maintained for a long time or the devs didn't care about keeping it up to date. The problem with Rails 5 is that there are still gems that are very useful and are either incompatible with Rails 5 or have fixed dependency on "rails < 5". Hopefully, the creators will update their gems in the near future.
