  • 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 https://docs.racket-lang.org/reference/treelist.html#(part._treelist)
and https://dl.acm.org/doi/abs/10.1145/2784731.2784739 )

  • The hash-filter-keys and hash-filter-values functions allow users
    to filter hashes using a predicate on either keys or values.

(see https://docs.racket-lang.org/reference/hashtables.html#%28def._%28%28lib._racket%2Fhash..rkt%29._hash-filter-keys%29%29 )

  • 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 https://docs.racket-lang.org/reference/vectors.html#%28def._%28%28lib._racket%2Fvector..rkt%29._vector-extend%29%29 )

  • 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.
