i understand this -- you need to use the new API to access
the new functionality.
my question was more: what's *broken* to let old code build
and run against the old API? clearly, apps need to have
new patches to talk to the new API, but is there a reason to
make it *impossible* to use the old API? i am not going to
claim they exist, but what if someone is running an older
netatalk for some reason, and they'd rather rebuild than
port your patches.
breaking source compat like this is just nasty.
