[Ipopt] Ipopt + MA27 compiled for Visual Studio 2008

At present we have two different downloads compatible with different 
versions of Ipopt due to a change in some data structures (or 
something). What versions should I be supporting - is the Ipopt front 
page correct in claiming the latest stable version is 3.9 (latest 
version 3.9.3 tarball dated 8-apr-2011)?

I'm inclined to only support the 3.11.x series - is this the right thing 
to do?
