Racket full changelog

Sort and highlight documentation-search results by core documentation and main-distribution packages
Add "language family" to documents, support filtering searches by language family, and highlight results that are not the main family
Add `'ios` as a compilation target distinct from `'macos`
Use `AI_V4MAPPED` and `AI_ADDRCONFIG` for hostname resolution via`getaddrinfo which improves IPv4 vs. IPv6 on some platforms
raco pkg: Add `uninstall` command prefer it to `remove`
raco pkg: Improve `--clone` transition for packages that are included in a distribution, and improve `--unclone` propagation to implied

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.
