Racket v8.14

posted by Stephen De Gabrielle

We are pleased to announce Racket v8.14 is now available from https://download.racket-lang.org/.

As of this release:

  • 64-bit ARM Windows is one of the standard pre-built downloads.

  • The compiler/demod language integrates demodularization into the program rather than an external tool. Using the language approach cooperates with other Racket tools and allows demodularization to be used on libraries. Additionally, demodularization handles submodules and can prune definitions, significantly shrinking the size of some programs. (#lang compiler/demod)

  • The contract-in form enables contracts to be specified in an importing module. (8.6 Attaching Contracts to Values)

  • The #%declare form supports the #:flatten-requires and #:unlimited-compile keywords (#%declare)

  • Identifiers such as case-λ, match-λ and λ are equivalent to their Latin-alphabet equivalents (case-lambda, match-lambda, and lambda) in more contexts, including uses of match.

  • The hash-filter function allows the use of a predicate to select a sub-table of a hash table. (hash-filter)

  • The module browser can perform filtering on submodules.

  • The raco test command-line form respects the current-test-invocation-directory parameter, and shows well-formed module paths in its output. (current-test-invocation-directory)

  • Racket CS allows the use of in-memory boot files.

  • The raco/testing collection brings together a variety of testing- related functions and forms. (raco/testing)

  • This release also includes many bug-fixes and documentation updates!

  • NOTE: This release (and version 8.13) have a known build problem that affects the builtpkgs source bundle on Windows. In order to avoid this problem, use a pre-built bundle or build using a source bundle other than the “builtpkgs” one. Nightly builds do not suffer from this problem.

Thank you
