Racket 8.2 freeware

Racket's interactive mode encourages experimentation, and quick scripts easily compose into larger systems. Small scripts and large systems both benefit from native-code JIT compilation. When a system gets too big to keep in your head, you can add static types.

8.0 Feb 14, 2021 New Release Racket 8.0 marks the first release where Racket CS is the default implementation.

Racket CS will continue to improve, but at this point it is ready to be the primary variant of Racket for all Racketeers. More details about the current state of Racket CS are available in the recent blog post.
Other notable changes:
Racket CS has better parallel garbage collection, a 10%–30% reduction in the size of generated code, and various targeted optimizations.
A rewrite of the test-engine package allows the #lang versions of teaching languages to produce linked test-failure messages.
The release comes with a new mark-up DSL for composing text to appear in the REPL (simple-tree-text-markup).
