Notice

Feature Pack 2 also includes all functionality from Feature Pack 1.

Always install both packages in this order:

1. language independent (updates language-independent components)

If you install a new language pack on your SharePoint Server 2016 farm, you must then reinstall the language-dependent update package.

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