  • This is build 16.0.5413.1001 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

Improvements and fixes

This security update contains improvements in SharePoint Enterprise Server 2016:

  • To improve the security of customer environments, Antimalware Scan Interface (AMSI) integration is now enabled by default for all new and existing web applications. For more information, see Configure AMSI integration with SharePoint Server.

  • Improves AMSI integration by not blocking web requests if AMSI can't successfully inspect the web request. A new health analyzer rule will notify SharePoint farm administrators if AMSI protection isn't functioning as expected.

This security update also contains an improvement in SharePoint Enterprise Server 2016. To get the improvement, you have to install KB 5002501 together with this update.

  • Adds a new health analyzer rule to check whether AMSI integration is enabled, and, if it is, to confirm that AMSI protection is functioning as expected. If AMSI protection isn't functioning as expected, the new health analyzer rule will notify SharePoint farm administrators through its health analyzer report, and provide recommended steps to fix the issue. For more information, see Antimalware Scan Interface (AMSI) protection may not be working (SharePoint Server).

Known issues in this update

New security enhancements in SharePoint Server might cause custom .aspx files not to be displayed under certain circumstances. Browsing to such a page generates a "92liq" event tag in SharePoint Unified Logging System (ULS) logs. For more information, see ASPX file cannot be displayed when you create a custom web part (KB5030804).
