You all know my love of powershell from previous posts; well, as of now, Powershell V4 is now available: http://blogs.msdn.com/b/powershell/archive/2013/10/25/windows-management-framework-4-0-is-now-available.aspx
Based on previous experiences, though, I'd wait a little bit to install it on servers just in case there's some incompatibility with an application (eg: when powershell v3 came out and was not able to be installed on an exchange 2010 server). Labels: powershell
