huh? who said anything about rewrites? Qt 5 is Qt 4, reorganised, with
a few source incompatible changes (things like socket fds now being
represented as qintptr instead of int - so QTcpServer's virtual will
need changing), a lot of binary incompatible changes, and a bucketload
of new features.

it's already possible to run e.g. Qt Creator on Qt 5, and the changes
required there were very minimal afaik. I've ported a lot of my own
work to run on either 5 or 4 the same way, with minimal use of ifdefs
for those source incompatible changes. The biggest change is that
things like #include <QtGui/QLabel> are now #include
<QtWidgets/QLabel>. That's it.

The change is an evolutionary one, not a revolutionary one. You don't
need to rewrite the entire world today, or ever, if you want to. If
you're happy with the functionality Qt gave you in the past, you'll be
equally happy with what it has to offer you now. Nobody's holding a
gun to your head.
