Today I was just checking my tweets and saw that the PowerShell team had released a new build of the Windows Management Framework v5, this time its the September build and it works only on Windows Server 2012 R2 or Windows 8.1 and if you have a previous version that was released in july of the v5 you have to uninstall that first and then you can install this version

here is a quote from the PowerShell team at http://blogs.msdn.com/b/powershell/archive/2014/09/04/windows-management-framework-5-0-preview-september-2014-is-now-available.aspx

The following is a list of all the new scenarios enabled since May 2014:

• Generate Windows PowerShell cmdlets based on an OData endpoint
• Manage .ZIP files with new cmdlets
• DSC Authoring Improvements in Windows PowerShell ISE
• New Attribute for defining DSC meta-configuration
• Use partial configurations DSC
• Cross-computer synchronization through DSC
• Get the current DSC configuration status
• Compare, Update, and Publish DSC configurations
• Audit Windows PowerShell usage by transcription and logging
• Extract and parse structured objects out of string content
• Extend the item noun to enable Symbolic Links
• Develop with classes in Windows PowerShell
• Register a PSRepository with PowerShell Get
• Network Switch management through Windows PowerShell (improvements)

I used a Azure VM to test and install this version

And once rebooted I can check via Get-Host what version I am actually running
