(probably obvious) Note -

Applications linked against the old version are *not* forwards compatible.

Found this out when a pre-commit dovecot build wouldn't authenticate against
a new-format ($5$) master.password  but would against an old-format one,
and a rebuild of the same package against the new lib would.

This also explains my Xscreensaver post to users@ as well. doh
