Indeed - every release we make generally includes many more little tweaks than we list out here. The vast majority are not noticeable to users, so there's little point listing them - but since Wikia is very customizable, it's always possible someone has used something that we've tweaked. That link is (hopefully!) a useful reference in case that occurs.
