Backwards compatibility of that kind is not guaranteed, but I can't think of 
any changes that happened that would actually break it.  If there are any 
relevant compatibility options in the build process, you should switch them 
on though.  It can't hurt, in any case.

Possibly in the archives of the list; I've not seen much documentation either.  
However if you have specific problems you might be able to ask for help on 
this list and figure out what's up.

Cheers,
