New Licensee Code → Extended Licensee Code

I'd like to change the name "New Licensee Code" to "Extended Licensee Code". I think it better conveys the idea of a revision of the system, instead of focusing on the fact that it came out afterwards

Search the repository documentation for every occurrence of “New Licensee Code” and review the surrounding references before changing the terminology. Done means the requested name is consistently updated to “Extended Licensee Code” without leaving outdated references behind.
