Well, I wrote the code to upgrade the DB, and I tested against every 
version that was provided to me, including some WordPress version 
numbered .72.  Whether files/templtes/themes break after the upgrade, I 
can't say, but I know that you should be able to take a database 
directly from .72 or after to at least 1.5.  I suspect that due to the 
way the upgrade code works, it'll take it directly to 1.6, too.

Same with the one I just did.
I have some code for that, if you need it.

I think there is room in the world for high-impact documentation that 
actually provides useful information.  See the attachment for what I 
envisioned.
