This came out months ago. As has already been pointed out, this replaces the old Citrix Online Plug-in. The main difference seems to be the installation and set-up. It was so convoluted under the old online plug-in you had to make sure you had the right version of JAVA installed just to run the installer. After that it never worked until you manually started the plug-in which was buried deep in the recesses of Mac OS. A normal user had absolutely no chance. It was like going back to 1997. Then there was the Citrix support or rather lack of it. The impenetrable Citrix website is anathema to the slickness and clarity that is Apple. Citrix make so many products and it is absolutely impossible to deduce what they all do, how (or if) they work together or how to use them. The Citrix website is completely impossible for anyone who doesn't work for Citrix to use and Citrix seem to be completely incapable of seeing their product miasma through the mind of someone coming to the Citrix universe for the first time. It's so opposite to Apple it's incredible.
