The new OSI is unfortunately behind schedule.  All the developers have day
jobs that have forced them to pay attention to other priorities.  It is in
progress, though, but there will certainly not be any code released in the
next few weeks--more likely the next few months.

Much of the OSI redesign is internal--it will make the library more
consistent, flexible, and extensible.  As far as the API feature set, the
new OSI will be pretty much a superset of the old.  If there are major
syntactic changes, then we'll plan to provide a compatibility layer to
help OSI1 users over the transition.

So if the old OSI suits your needs, I'd recommend going ahead and
developing for it.  If not, let us know what features you need.  That way,
we can incorporate them into OSI2, and perhaps we can back-port them to
tide you over.

Let me know if you need any more information.  Thanks for your interest.
