Racket v8.13
----------------------------------------------------------------------
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 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.
