Note To apply this security update, you must have the release version of Microsoft SharePoint Server 2019 installed on the computer.

Improvements and fixes

This security update contains fixes for the following nonsecurity issues:

  • Removes the Link command from the New menu in custom lists if content types are enabled.
  • Fixes an issue that prevents users from switching content type when they create items in a list.
  • Users navigate to a document library and open a Links list in Job Access With Speech (JAWS) by using a keyboard shortcut (Alt+F7) to see all links on the page. In this situation, every document in the library will have the Open Menu link to open the Edit Control Block (ECB) menu. Therefore, it is not possible to know which document belongs to which link. This update fixes this issue.

Note To fix these issues, you have to install update 4484271 together with this update.
