Once 7.0 is released, then there is a promise of binary compatibility
for any software compiled under some 7.x version to work certainly with
any later 7.x version, and possibly with any earlier 7.x version as
well[*].

However, 7.0-RELEASE isn't actually out there yet, and the Release
Engineers may well be making last minute incompatible changes.  If
freebsd-update recommends wholesale updating of ports, then there's
a good reason for that.  I will state though that I've been tracking
7.x since fairly shortly after the RELENG_7 branch was created and apart
from the big 6 -> 7 update I've not seen any compatibility problems with
ported software.

        Cheers,

        Matthew

[*] I can't remember if the backwards compatibility with the major
version is guaranteed or not.  Forward certainly is.  Also there's
the new symbol versioning thing within shlibs that changes the way
this sort of thing works.
