Notes: 

  • This is build 16.0.5456.1000 of the security update package.

  • To apply this security update, you must have the release version of Microsoft SharePoint Enterprise Server 2016 installed on the computer.

This public update delivers Feature Pack 2 for SharePoint Server 2016. Feature Pack 2 contains the following feature:

  • SharePoint Framework (SPFx)

This public update also delivers all the features that were included in Feature Pack 1 for SharePoint Server 2016, including:

  • Administrative Actions Logging

  • MinRole enhancements

  • SharePoint Custom Tiles

  • Hybrid Taxonomy

  • OneDrive API for SharePoint on-premises

  • OneDrive for Business modern user experience (available to Software Assurance customers)

The OneDrive for Business modern user experience requires an active Software Assurance contract at the time that the experience is enabled, either by installation of the public update or by manual enablement. If you don't have an active Software Assurance contract at the time of enablement, you must turn off the OneDrive for Business modern user experience.

Known issues in this update

This security update introduces a change where the Microsoft.SharePoint.ApplicationPages.SPThemes class is marked as unsafe in all Web.config files. This change has inadvertently caused some SharePoint PowerShell cmdlets to not function properly. For example, the Test-SPContentDatabase cmdlet, the cmdlet that enables the Document Sets feature, and the cmdlet that enables the Video and Rich Media feature. The workaround is to perform these operations on the corresponding UI pages.

Microsoft is researching this issue and will update this article when a fix is available.
