Improvements and fixes

This security update contains the following improvement in SharePoint Server 2016:

  • This update makes improvements to enable the new Japanese era in SharePoint Server 2016 when it is available.

This security update contains the following improvement in Project Server 2016:

  • This update adds support in the client-side object model (CSOM) for setting the EnterpriseProjectType of a project by using the REpresentational State Transfer (REST) Application Programming Interface (API)..

This security update contains fixes for the following nonsecurity issues in SharePoint Server 2016:

  • Assigned Badges icons are unexpectedly hidden in a discussions list, a Members list and the My Membership web part in a SharePoint community site.

  • When you try to add a SharePoint hosted app in a SharePoint Online site, the app is not displayed on the App from your organization page.

  • When you run a search query, the alternate access mapping function is always called. This call is expensive and may lead to a high CPU load on the server.

  • When you run a search query by using the REST interface that contains the SortList query parameter, the query may fail with a SearchServiceException exception because the SortList parameter is case-sensitive.

Known issues in this security update

After this update is installed, search queries that are executed from a nondefault zone URL (an extended zone) don't return any results. 

To resolve this issue, install February 27, 2019, update for SharePoint Enterprise Server 2016 (KB3085363).
