With the July 2024 release, the old 'Sites' term is no longer in use and is replaced with 'Field'.
Previously the term 'Sites' was used for mostly two things:
1) The module that takes Asite to mobile devices is now called Field. Under that module we both have Field in the web and as a mobile app.
2) Project Sites are now referred to as Locations throughout the Field module.
Below you find a few screenshots with the new names, though we have updated it in many other places too:
