The value of the <b>PowerShellVersion<\/b> registry entry in HKLM\\SOFTWARE\\Microsoft\\PowerShell\\1\\PowerShellEngine has been changed to <b>2.0<\/b>.<\/p>\n<p>2. Added new language keywords: <b>Data<\/b>, <b>Cmdlet, and DynamicParam<\/b>. Any commands called <b>data<\/b>, <b>cmdlet<\/b> or <b>dynamicParam<\/b> are interpreted as language keywords and result in parsing errors. <\/p>\n<p>3. Changes in argument separator behavior. In Windows PowerShell 1.0, <b>$a.method(,1) <\/b>is interpreted as a call with an array of 1 element, but <b>$a.method(1,,2)<\/b> generates a parsing error. In Windows PowerShell V2, both formats generate parsing errors.<\/p>\n<p>4. New cmdlets and variables have been added. These are listed below. These new elements might conflict with variables and functions in profiles and scripts.<\/p>\n<p><b><\/b><\/p>\n<p><b>Breaking Changes to Windows PowerShell V2 (CTP)<\/b><u><\/u><\/p>\n<p><u><\/u><\/p>\n<ol>\n<li><a name=\"_Setup_with_scripts\">The attribute declaration for script cmdlets has changed.<b><\/b><\/a>      \n<ol>\n<li>Attributes like [Mandatory] or [Position(0)] are now specified as [Parameter(mandatory=$true, position=0)]. <b><\/b><\/li>\n<li>Attributes like [ValidateNotNull] now requires parens, like [ValidateNotNull()]         <br \/><b><\/b><\/li>\n<\/ol>\n<\/li>\n<li>The remoting parameter sets (Runspace, Uri, and ComputerName)have been removed from the <b>Invoke-Expression<\/b> cmdlet.
