The version number matches the latest version of Racket. It's simply the tool used to generate the book site that inserts the version number. It's more relevant in the Racket docs than in the book though.

It's not one "toy" language. It's a series of languages that becomes gradually larger. It has the exact same syntax and semantics as the "real" Racket. If a language is small, the compiler can give very precis
