Racket v6.2.1 is now available from http://racket-lang.org/
Version 6.2.1 patches the recent v6.2 release in three small ways:
- For the How to Design Programs teaching languages, DrRacket offers an option to use the old style for printing the constants true, false, and empty instead of #true, #false, and '().
- The teaching languages come with some additional functions to match the August 2015 stable release of HtDP 2nd edition.
- A repair to the compiler avoids an infinite loop at compile time for certain expressions that should loop forever at run time.
