Racket version 8.7 is now available from
https://download.racket-lang.org/
As of this release:
-
Typed Racket offers Shallow and Optional modes for its gradual
types. These modes lower the cost of interacting with untyped code,
but provide less protection against buggy interactions.
(see https://docs.racket-lang.org/ts-reference/behavior-of-types.html ) -
Racket uses Unicode 14.0 for character and string operations, and
includes grapheme operations. DrRacket supports emojis.
(see https://docs.racket-lang.org/gui/editor-overview.html#%28part._graphemes%29 ) -
Racket supports RV64G (RISC-V).
-
Programmers can disable definition shadowing using
(#%declare #:require=define).
(see https://docs.racket-lang.org/reference/module.html#%28form.%28%28quote.~23~25kernel%29._~23~25declare%29%29 ) -
The module dependency graphs available using raco dependencies-graph
and DrRacket's Module browser are faster and have new package
filtering support.

DrRacket is more responsive when killing programs that produce a lot
of output. -

from "below").
