Where are the revision pages? (Roadmap 6.0)

[kkessels2019]

The following feature was announced on the roadmap for version 6.0:

"Revision History
Both pages and posts will get complete revision history for all the changes made to the content. This will enable the editors to:

Create a draft for an already published item.
Preview an earlier version with the possibility to restore it.
Undo changes made to a page or post."

I have installed version 10 and can't find a way to recall a changed page in the admin area. The setting option how many versions are saved, I have found. This is set to 10, but how can I view an older page?
