Comment:

 Thanks for the report, hissy. To spell out the "unexpectedly fails" bit:
 In 4.0, `category_exists()`, when not passing a `$parent` param, will
 return the oldest category matching the `$cat_name`, regardless of parent;
 in 4.1, it'll return the oldest category matching `$cat_name` that has no
 parent. Fix + unit tests are incoming.
