Report on all changes in a space within a certain timeframe

We are using Confluence to generate customer facing documentation. User groups have requested me to generate a (monthly) report of all changes in space, one that does not require any extra clicks.

What we need is the style of notification that is sent after a single page modification (changes marked in the message) but then accumulated for all changes in a month. But, if I make a change myself, obviously I do not get a notification for that, so the only way around it would be to create another user and have all notifications sent to a that e-mailadres, and monthly, print out all e-mails.

I have tried the daily digest, but this only shows a page was changed, not what was changed.

I have tried the RSS feed, with the same problem.

I did not find any macro's either that work on space level.
