I think it is worth adding a paragraph about what editions are and how they work. In particular:

  • editions allow small breaking changes (e.g. syntax), but don't change the semantics of code written in previous editions
  • the compiler supports and will continue to support code written in editions 2015, 18, 21
  • old code will continue to compile, and projects written in any edition can use libraries written in any edition
  • migrating an active project to edition 2021 should be mostly a matter of running cargo fix
