I noticed by chance that this page has changed yesterday: https://docs.iredmail.org/upgrade.iredm … 1.5.2.html

I printed it few days ago to look at what changes before doing it, and it was 2 pages long. Today i noticed it became 6 pages long.   

This can be confusing because those who made the changes in the past days, could miss the last changes.
I think there sould be a new number of version, or some kind of notifications about the changes, otherwise someone thinks to be up to date, but misses some piece.
