provide facilities for getting a list of all changes to a space

my workflow within confluence (large wiki with 30+ very active spaces) is to watch the space i'm responsible for and review every change that comes into my email box as a result. This works fantastically well. Recently I took a sabbatical and my account was disabled while I was gone, and thus no change notifications were sent. Upon return, I am struggling to reconstruct what happened as (via your support team) there is no way to list all changes for a space (including additions, deletions, tag changes, moves into/out of the space, etc) within confluence itself, retroactively.

So, I'm looking for a widget or some other method to give me a date-ordered list of such changes.
