 What's New in Libc++ 16.0.0?
 ============================
 
+The main focus of the libc++ team has been to implement new C++20 and C++23
+features.
+
+The C++20 format library has improved but it not yet considered stable. The
+main improvements are additional formatters for the chrono calendar types. Work
+on formatting ranges has started.
+
+The C++20 ranges library has been completed and is no longer experimental. Some
+``views`` have not been implemented yet. Work on C++23 ranges has started.
+
+The C++20 spaceship operator has been added to more types, the work is still
+ongoing.
