Stata on all nodes has been upgraded to 9.1. You can find out what these upgrades and updates contain on the internet version of the 'help whatsnew' command. Note that on VRDC6401, you need to start Stata 9 with 'stata9' or 'xstata9', the default Stata version still being Stata 8.
And the GUI of Stata 8 and Stata 9 look identical...
