  • 64-bit ARM Windows is now a standard pre-built download
  • The `compiler/demod` language integrates demodularization into the program with support for submodules and definition pruning
  • The `contract-in` form enables contracts to be specified in an importing module
  • The `#%declare` form supports the `#:flatten-requires` and `#:unlimited-compile` keywords
  • Identifiers such as `case-λ`, `match-λ`, and `λ` are equivalent to their Latin-alphabet equivalents in more contexts including uses of `match`
  • The `hash-filter` function allows using a predicate to select a sub-table of a hash table
  • The module browser can perform filtering on submodules
  • The `raco/testing` collection brings together testing-related functions and forms
Changed 2
  • The `raco test` command-line form respects the `current-test-invocation-directory` parameter and shows well-formed module paths in its output

  • Many bug-fixes and documentation updates included in 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.

  • The contract-in form enables contracts to be specified in an importing module.

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

  • 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.

  • 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.

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

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

  • 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.
