Contains the following improvements:

• Adds the new Japanese era name in the Japanese word breaker to make sure that the new era name can be correctly broken when during a search.

• Spanish is now an option among the search language preference in the SharePoint classic search if users from Argentina and other countries from South America set Spanish as their language preferences in the browser.

Contains fixes for the following nonsecurity issues:

• In some circumstances, if you delete a few views that are associated with custom fields that support multi-value selection from a lookup table in the database, and then you run the Repair-SPProjectWebInstance cmdlet, you find that the first view isn’t generated in the database.

• Files that have Information Rights Management (IRM) protection in Modern UI are blocked from being uploaded to a document library.

• Existing folders can be marked as special folders only if they are empty. Now, folders that have existing content can be used.

• Certain calendar picker options for setting CalendarWeekRule update the value incorrectly.

• After you install the January 2019 update, the “Resources" web part is removed from the Central Administration homepage. This update corrects the issue and restores the “Resources" web part to the Central Administration homepage.
