If you give me enough money, I could take the time to look for the right MZ thread listing 2.0 feature set and write a nice text out of it.

If the sum is important enough, I could also rewrite parts of Ambient, MUI4 and Sputnik changelogs too.
I think that should cover 90% of it.

With even more money, I would dig the ML archives and add all kind of minor features implemented on user request (I remember Lord once asked to be able to zoom window by a double click on the title bar, f.e...)
That should cover 99% of the thing.

But it's a so boring, long, uninteresting and stupid work... the sum would have to be pretty high :-)
