Can I play devil's advocate and say why not just bump up the minimum
to 3.3 or even later?  Obviously, backwards compatibility is nice, but
you've got to measure the risk/reward ratio.  As a user, I'd rather
see new, inovative features, improvements, etc that a newer version
could provide.  I would have to say that the folks who run myth for
the most part rarely have a problem keeping up to date with software
releases.  Myth is not like a pre-packaged software component (or
environment) that anyone can expect to work without setting up
additional components to make it work.  If one of those components is
a minimum version of QT that's greater than what the current version
of myth requires, then I call that progress. Most of us would happily
go to QT4 if that was the direction the developers took.  And for the
few who don't/can't upgrade past 3.3, then perhaps they don't intend
to upgrade their myth installs either.  They can still run a version
of myth that is compatible.

Just my 2 cents.  Either way, I think it's a good idea that these kind
of things are discussed instead of just simply decided without talking
through the issues.  Keep up the good work guys.


Thanks!
