Racket v8.13

posted by Stephen De Gabrielle

We are pleased to announce Racket v8.13 is now available from https://download.racket-lang.org/.

As of this release:

• The racket/treelist and racket/mutable-treelist libraries provide list-like containers that support many operations in effectively constant time, including appending and extracting sub-lists without mutating the given list. Treelists are implemented as RRB Vectors, invented by Stucki, Riompf, Ureche, and Bagwell. (see 4.16 Treelists and RRB vector: a practical general purpose immutable sequence, ICFP 2015)

• The hash-filter-keys and hash-filter-values functions allow users to filter hashes using a predicate on either keys or values. (see 4.15 Hash Tables: hash-filter-keys, hash-filter-values)

• The vector-extend and vector*-extend functions provide a way to pre-populate the prefix of a newly allocated vector using the elements of an existing vector. (see 4.12 Vectors: vector-extend)

• Command-line raco setup, package update, and package installation use terminal control (when available) to show what they are working on more compactly and with a progress bar.

• Racket v8.13 uses Unicode 15.1 for character and string operations.

• Machine-specific cross-module optimization allows improved support for static generation of foreign-function bindings.

• The scribble/acmart language uses v2.01, which avoids errors concerning the hyperref package in some latex installations.

Thank you
