What Grasshopper Version do I need?

Hi there, 

I hope this is in the correct section and someone can help me. Im looking for a version of grasshopper that will work with my current version of rhino. Im an architecture student and have borrowed a copy of my friend but I am unable to update it to the latest service release as I dont have his details. Could someone point me in the right direction please?

Many thanks,

Alex

Version: Rhino 4.0.2008.827
