[codecov]

The changes mainly address updating the CHANGELOG and release notes, and fixing a bug in URLCategory model related to assigning function reference instead of calling form_list function for regex_patterns and regex_patterns_retaining_parent_category attributes. Generally the changes are well made but there's a small error in dates that could naturally cause some future confusion.
