After installation, remember to run the SharePoint 2019 configuration wizard (SharePoint 2019 Products Configuration Wizard), or the following command:
PSConfig.exe -cmd upgrade -inplace b2b -wait -cmd applicationcontent -install -cmd installfeatures -cmd secureresources -cmd services -install

Important

Always install both packages in this order:

language independent (updates language-independent components)
language dependent (updates language-dependent components)

For language-dependent packages (language dependent), it does not matter which language you select, because each package contains updates for all languages.

If you install a new language pack on a SharePoint Server 2019 farm, you must subsequently reinstall the language-dependent package (language dependent).

Remember that, in addition to SharePoint, the Distributed Cache service must also be updated; see How to update Distributed Cache correctly and, for Office Online Server, you must have the current RTM version; see How to update Office Online Server.

Previewing Master Page crashes because of a null reference exception.
Windows Server 2016 started to use the period (“.”) as the time separator for Finnish and certain other locales. This change causes an issue within the SharePoint Object Model datetime parser. To resolve this issue, SharePoint will now use the unparsed datetime value.

The complete-match search was working only for the farm level managed properties. With this update, we can also use complete-match search on the managed properties created in site collection level now.

This update fixes the following issues in Project Server 2019:

When a SharePoint update is applied and the SharePoint Products configuration wizard is run, the reporting association views are dropped but not re-created.
After you upgrade from Project Server 2010 to 2019, if you edit a project in PWA and delete an inactive task, after you save the project, you may be unable to reopen it.
You are unable to update and clear local Duration and Outline Code field lookup values through the client-side object model (CSOM).
Consider the following scenario:
- You create a project with a single task and large number of resources.
- You add all resources to the task.
- You save and publish the project.
- You edit the project in PWA.
- You click the drop down for the Resource Names column.

In this case, you will see that some resources are no longer assigned to the task.
