As a side note, I think it's unfortunate that vendors would decide to stop maintaining the software that supports some parts that they still sell and support. That is a problem IMHO.
Either you support a product, or you don't, and the necessary tools to use it are every bit as important as the product itself.
As I said in another thread, it looks like Lattice is gonna do the same thing with Diamond.
I understand that it takes resources to maintain software, but I see little justification from a customer's POV for this kind of decision.
The rationale that the software "just works as it is" is a pretty limited one. You still make customers' life harder - like regarding OS support, and the remaining list of bugs that will never get fixed, etc.
Just MO. If everyone is happy with that, so be it.
