IDEA version history?

I have been using IDEA for a long, long time. Just out of curiosity I would like to have a look at a version history (starting from IDEA 1.0).
Does this exist somewhere or can anybody contribute? Maybe add to the wikipedia article on IntelliJ IDEA?
I think I started with IDEA 3.0 and seem to remember generics made it into 4.5, but other than that my memory of the older versions is quite blurred.
