A new cumulative update (January 2025 CU) has been released for SharePoint Server Subscription Edition.

SP Build:
16.0.17928.20356

Starting with the March 2023 CU, updates for SharePoint Server Subscription Edition are released as a single package (known as an Uber package) containing both language-independent and language-dependent fixes. Only one package needs to be installed to fully update the server.

SharePoint Subscription Edition CU – KB articles describing the CU:

Important notes

To speed up CU installation, I recommend following the guidance in How to speed up CU installation in SharePoint Server Subscription Edition.

The language you select when downloading the update does not matter because the same package is downloaded for every language.
