I've been thinking about that recently. The main reason I'm going for 3.4 is
that it's what I started with about a year ago. Since then I've had to work
on other things most of the time. 

Going from 3.0.3 to 3.4 required quite a bit of changes to the target files,
lots of things becoming hooks instead of macros etc as well as some things
being done differently. All of that is resolved now however.

How much typically needs to be done when going from 3.4 to 4.1? If it's alot
then I will finish 3.4.6 first since it's pretty close. It's quite an
improvement over 3.0.3 too.
