Microsoft today made available the Visual Studio ALM Feature Pack 2 to customers with VS Ultimate with MSDN, VS Premium with MSDN or VS Test Professional with MSDN. FPs enable you to extend Visual Studio 2010 with capabilities that enhance and complement the existing tools.
"Being mindful of the number of things we suggest people install, we've made FP2 cumulative with FP1. One installer will get you both. If you already have FP1 installed, be sure to read the instructions linked from the "IMPORTANT!" section on the download page," explains Microsoft.
