Photoshop Version History

[bachscuttler]

I occasionally write simple Photoshop Tutorials for a couple of other sites and have always wanted to add version compatibiliy.

I've done some hunting around online (Geez, PS has been around since 1990!) and found this link as a good starting point:

Anyone have any better links?

It is interesting to see how some of the dialog boxes look pretty similar from CS2 from all the way back to v1.0.
