There's more...

Each PowerShell release comes with release notes that dive into the details of changes introduced with that version. These pages are updated with community contributions, as PowerShell is now partially open source:

• WMF 5.0 Release Notes: https://msdn.microsoft.com/en-us/powershell/wmf/5.0/releasenotes
• WMF 5.1 Release Notes: https://msdn.microsoft.com/en-us/powershell/wmf/5.1/release-notes

The documentation is published on GitHub and accepts contributions from users via pull-requests so users may help improve the documentation. You'll find PowerShell documentation on GitHub at https://github.com/PowerShell/PowerShell-Docs.

Complete documentation is available on TechNet, see the Windows 10 and Server 2016 PowerShell module reference at https://technet.microsoft.com/en-us/library/mt156917.aspx.
