The biggest reason "to wait a bit" is that the system is still changing
a lot. After the big number of kernel changes in the last months,
we are now working on some important userland issues. This means that
from time to time, the PREVIEW/STABLE tag will show some major
changes. For example, the next time the tag is slipped, all major
versions have increased and you'll most likely want to rebuild all
ports. It's normally not so much a problem of testing, but you should
keep this in mind when doing updates.

The update from most versions of 4.x to the 1.2 release should work.
If you have problems, please report them. We don't and can't support
upgrades to head without a lot of hassle, but updating from release 1.2
(or nearly release) to HEAD/PREVIEW is considered important.

It should just work. You _might_ want to rebuild it, but it should not
be necessary.
