Unfortunately, the upgrade path will remain fairly broken with respect to compiled applications outside of the base system until we have a compat6 library set (and possibly more versioning work on libraries?). Some libraries have now been bumped, but not all, and as a result older applications may find themselves linked against libraries with differing ABIs from each other -- i.e., a 6-STABLE libc left over from before your update and a 7-CURRENT libutil (random example), which can result in application crashes. This will presumably get resolved before we get anywhere close to a release, but in the mean time, it is advisable to rebuild all applications when going from an earlier branch to the 7.x branch, or when jumping forward significantly on the branch.
