Note 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:

Improvements and fixes


This security update contains improvements and fixes for the following nonsecurity issues in SharePoint Server 2016:
  • Changes the "Scheduled Start Date" and "Scheduled End Date" fields in a publishing page to format the date field according to the correct locale.
  • Updates SharePoint search crawler to send GET requests by using HTTP 1.1 if the HTTP 1.0 requests fail.
  • Updates the Search word breaker to tag IP addresses and GUIDs as named entities for all languages except Korean.
  • Fixes an issue in which axis values may be truncated when you use SharePoint Server 2016 to convert a file that contains charts to PDF.
  • Fixes the HTTP 404 response error when you access site collections in newly created or mounted content databases.
  • Consider the following scenario:
  • You have a web application that uses Windows claims authentication only.
  • You create an Active Directory (AD) user that has a mail account name that's not the same as the user principal name (UPN), and the AD user doesn’t exist in the UserInfo list.

In this scenario, the AD user isn't validated.
