You should definitely pay attention to the release notes (RELEASE.html)
of whatever version you choose to migrate to. Perl 5.8 is a better
choice, if there are no language issues. Perl 5.8 is very compatible
with Perl 5.6 on the language side, so whatever problems you encounter
with one, you are most likely to encounter with the other. On the module
level, Perl 5.8 has a changed XS. You have to rebuild any modules you
may have written, and you may find more problems with 5.8 if an XS
function you liked no longer exists (sv_setpviv() comes to mind).
