Explain why retail version of Office 2019 received feature updates
I noticed that the November update of the retail version of Office 2019 is version 1810, which contains feature updates. However, this contradicts the official Microsoft Office 2019 FAQ documentation (https://support.microsoft.com/en-us/help/4133312/office-2019-commercial-for-windows-and-mac-frequently-asked-questions).
Can an explanation be given to this contradiction, please? As an add-in developer, I'd like to understand the official Microsoft stance on this so that I can plan accordingly.
