Please refer to this. I made 3 little edits in a three-minute period (timestamps 19:29:41Z, 19:30:48Z, 19:32:08Z). In the olden days, this would be aggregated into one edit for the record. Now it shows as 3 edits.
The only difference this makes is I will now try to be more careful before hitting the "Save edits" button. But before I enjoyed the freedom to hit it and, if I discover a quick little typo or something I missed, to edit again, without this appearing as a separate edit.
