Having made the switch from 3.0 to 4.0 during the
development of Trails, it took some time but was
definitely worth it.  I think 4.0 is a tremendous
improvement over 3 for sure.  

However, if 5 is basically a completely new web
framework with no easy upgrade path it would be a
tough pill to swallow..  I also find it rather strange
that we're going to have another new IOC framework.  I
had just gotten to the point where I could really see
the beauty of Hivemind and was considering moving
Trails in that direction.  But I'm probably going to
sit tight until I see what Tap5 brings I guess.

Like someone else pointed out, if it is really
something completely different, maybe it shouldn't be
called Tapestry?
