Hopefully soon, but no date has been set.  I would guess 1-2 months.

OK, I now changed my auto-detector in Makefile.PL to do a test compile 
and check the allowed number of
args in plpoly3 instead of looking at the library version.  I can't 
assume that any target system
will have pkg-config installed.

All:  Please keep the API-breaking changes to an absolute minimum!  The 
code for perl/PDL to detect
different versions is ugly and takes much time to maintain.  It would 
have been preferable to just create
a new plpoly3 function with the extra argument instead of changing the 
old one.

Thanks!
