Stefan,
Is the OOS CUs truly cumulative updates which encompass all prior updates? My intent is to build an OOS farm with the ‘base’ OOS package and the Dec 2021 CU onto Windows 2019 servers, however reading article at https://www.microsoft.com/en-us/download/details.aspx?id=103708 refers to the Dec 2021 CU as a Security Update.

Hi Sue,
it’s both – a security update and a cumulative update.
All security updates for OOS are also cumulative updates.
Cheers,
Stefan

Is there somewhere a list with the build numbers of office online server? For Sharepoint I found many of them, but not for OOS.
