Rail 4.0.2 or the latest

Should I install the latest Rail or 4.0.2?

I guess it doesn't matter.

This version change doesn't really matter, but in general it really depends on how much you know about Ruby and Rails. If you're a beginner and trying to follow a tutorial, it's much easier to go with whatever version of Ruby and Rails the tutorial is using, especially when major version shifts happen (like Rails 3 vs. Rails 4).

It depends β€” I've typically just gone with the latest version of rails and gems β€” but that means that you're going to be stopping troubleshooting along the way. It gets easier though β€” and with gems, be sure to look at the current documentation. Things can change a lot between .x versions.

When I follow the latest docs, I don't have much trouble.
