 # Windows PowerShell Language Specification 3.0
 
-The _Windows PowerShell Language Specification 3.0_ was published in December 2012 and is based on
-PowerShell 3.0. The specification document is available as a Microsoft Word document from the
-Microsoft Download Center at:

-That Word document has been converted for presentation here on Microsoft Learn. During conversion,
-some editorial changes have been made to accommodate formatting for the Docs platform. Some typos
-and minor errors have been corrected.

-> [!IMPORTANT]
-> The contents of this documentation may not reflect the current state of PowerShell in its current

-In PowerShell, each value has a type, and types fall into one of two main categories: **value types**
