But yes indeed. The Changelog should describe the patch as is, and the differences between this and the previous version are relevant only to the reviewer who saw the previous version too. But once we commit the patch, the previous version ceases to exist (in the commit history) and therefore such comments loose their intrinsic meaning and should go away too.
