Addresses
Users can now edit their own addresses, which can be referenced by plug-ins such as Craft Commerce.
Full name
For users, from Craft CMS 4 onwards, one each field Full Name is used, instead of separate First Name and Last Name fields. First and last names are automatically detached at the front end of a website or web application.
Inactive users
It is now possible to manage users who represent a person or entity but do not actually have login credentials.
Extended support for formatting country settings
Users can now set their markup country setting to any known country setting; not just those for which the control panel is translated.
