Unlike the normal "recent changes" page, these options can summarize edits to the same page and let you dynamically expand and collapse the list items. For multiple edits to the same page, it also provides a single "changes" link which will show you a view of the differences (diffs) between these combined edits and the last non-recent revision.
After changing the Advanced options, the "Recent changes" list takes effect immediately and can be reversed by unchecking any option.
