Howdy, at the end of 2020 Microsoft did a lot of work on the Microsoft 365 roadmap.
Starting 2021 the item number in the roadmap decreased from 1394 to 848 items.
Before the items were removed, lots of them were set to “launched”. And other changes took place.
This was not cause be new feature, feature updates, and so on, but by housekeeping in the roadmap data.
