In the next few weeks (August 2015) we will be releasing a supported “Production Preview” of Windows Management Framework (WMF) 5.0. Later, in Q4 of 2015, you should be able to download the RTM version of WMF 5.0.

WMF 5.0 Production Preview will differ from previous previews of WMF 5.0 in the following ways:

• It will be fully supported until three months after WMF 5.0 RTM. By ‘fully supported’ we mean we will investigate any production blocking issues and provide a workaround or update as necessary.
• All features in the production preview are production ready. No experimental items will be in this package.
• You must uninstall all previous releases of WMF before installing the Production Preview.

Both of the upcoming supported versions of WMF 5.0 (Production Preview and RTM) will incorporate feedback regularly provided by our community of WMF 5.0 Preview users. Please deploy WMF 5.0 Production Preview and provide early feedback to make WMF 5.0 RTM even better.

Relation between PowerShell version in WMF 5.0 and Windows 10:

PowerShell version (5.0.10240.16384) that ships in Windows 10 RTM is supported like any other Windows component that ships in Windows 10 RTM. Supported versions of WMF 5.0 will ship the same PowerShell codebase that ships in Windows 10 RTM along with additional fixes that address customer reported gaps and bugs. The version of PowerShell that will be available in WMF 5.0 RTM will come to Windows 10 through a future update.
