OK I think I've braindumped what was immediately on hand. We really need to think about how this is going to be categorised and structured (e.g. categories) and what information should be visible and how and where.
I've just thrown what's easily in my head, but there's plenty we can get hold of, such as when versions were released, and I can probably start digging out lists of what features were added/removed when for different platforms.
There are more platforms, too, this was just what was in my head that I could easily bring to mind...
