I understand what you mean, but the page number is not necessarily what an author expects it to be after all changes are applied. You’d be very frustrated to be told to look at page 100 when the actual change appears on 102.

I mean adding page number for new information. Like: Microsoft-managed conditional access policies for management portals, check page 100.

We’ve thought about inserting change markers but the overhead (time, effort) is probably too much for the benefit we think would be achieved. We think about this kind of stuff all the time, but right now we prefer to use the available time to keep on top of the changes that occur in Microsoft 365.

I’m afraid so. Our value proposition is that we publish a completely new book every month where all the changes are integrated with the rest of the text. It means that what you read is our current view on a topic without the need to consult change logs or anything else.

And how then changes should be checked not re-reading whole chapter? ) Just search for the text?

No. The page numbers are changeable and wouldn’t be accurate.
