December 10, 2019, update for SharePoint Enterprise Server 2016 (KB4484178)

• Adds two new managed property settings for Search: Language Neutral Tokenization and Finer Query Tokenization. The properties are available as two check boxes when creating any new managed property, or when editing a custom managed property. Language Neutral Tokenization is for multilingual content and Finer Query Tokenization is for the content that contains separators such as dots and dashes.
  

  Note To enable this improvement, you also have to install update 4484181 together with this update.

• Improves the performance of loading a page which contains Search Result Webpart.
• The complete-match search was working only for the farm level managed properties, with this update you can now use complete-match search on the managed properties created in site collection level as well.

• When you try to open InfoPath Filler forms from a SharePoint forms library, InfoPath Filler doesn't open the forms; instead you are prompted with an Internet Explorer dialog box to select Open/Save/Save as.
• When Document ID feature is active, if you export and then import the site collection, a "date out of range" exception occurs.
• Fixes the issue that users can't use custom managed properties to sort the search query result. 
• When you send email messages with multiple attachments that have a same attachment name, the email messages are deleted and aren't saved in a list.
• When you open a lookup column's link in a new window or new tab, you receive a "404 Not Found" error.
• When a web application uses Default Configuration to configure SAML-based claims authentication with Active Directory Federation Services (ADFS) and the people picker account resolution, users from an external trusted domain experience the following issues:
• They are unable to log on to a site.
• They can't be resolved by People Picker if they are set up by using ADFS with "Email" as the identity claim.

• Previewing Master Page crashes because of a null reference exception.
• SharePoint doesn't honor group memberships for users from trusted domains. This results in access denied errors to resources to which they should have access.

• Adds the ProjectLastPublishedDate field to Project Server OData Projects entity so you can, for example, do a REST call to get a project's last published data.
• You are unable to update and clear local Duration and Outline Code field lookup values through the client-side object model (CSOM).
