Racket v8.0
posted by John Clements Racket version 8.0 is now available from https://racket-lang.org/. * Racket 8.0 is here!* Racket 8.0 marks the first release where Racket CS is the default implementation. Creating, polishing, and adopting Racket CS has been a 4-year effort involving the entire Racket community. At this point, Racket CS is faster, easier to maintain and develop, and compatible with existing
Racket v7.0
posted by Vincent St-Amour Racket version 7.0 is now available from http://racket-lang.org/ Racket version 7.0 includes substantial internal changes toward the long-term goal of replacing Racket’s current runtime system and supporting multiple runtime systems.

The Racket Blog: Racket v6.6
Racket version 6.6 is now available from http://racket-lang.org/ The new Macro Profiler command-line tool (`raco macro-profiler`) shows how macros contribute to the final expanded code size of a program.
