I have Mathcad 2000 Professional and would like to know if there are any upgrades available?
MathCAD has been updated and now it's called differently: MathCAD Prime. It's actually the same application, but with updated and new features that are available to use. There is also an EXPRESS version which is something called Lite, with fewer features, but still power as its previous or full versions.
I recommend checking the following link to see exactly what I am talking about: http://www.ptc.com/engineering-math-software/mathcad
