I believe so. I seem to recall that it broke the snmpd.conf 'table' token.
Wes also pointed out that anyone wanting to look at the data itself would have
been using the linked list pointers, thus breaking backwards compatibility.

It's the old backwards compatibility bug biting us again. I'm comfortable with
providing wrapper functions to provide an emulation of the linked list
pointers. I don't think having to change
item = item->next;
to
item = next_item(item);
is to onerous. But I've always lost this type of argument in the past. ;-)

Not on existing user code. But if all internal examples and mib2c conf files
are updated to use the new version, it should fade over time.

I did give him a hard time about the name. I agree that the new one sucks.
