Racket v8.0
*** 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 programs. 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 (https://blog.racket-lang.org/).
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).
* Redex has an added `define-overriding-judgment` form and improved
error source location reporting.
* Windows scrolling speed reflects the system preference.
* The db package uses the utf8mb4 charset for MySQL connections.
