Just started to learn about moodle and noticed that the notice said this page is no longer valid
Is there a most recent or "validated" one?
The most detailed, comprehensive and up to date diagram is here
That is forMoodle 3.4 and I intend to create diagrams for 3.5 and 3.6 when 3.6 becomes available. Note that in addition to the main diagram there are diagrams for the sub-systems.
