| 8.16 | Mar 3, 2025 | New Release | As of this release: Racket has expanded support for immutable and mutable treelists: A variety of new treelist utility functions are available: treelist-filter, treelist-flatten, et cetera. The mutable-treelist-prepend! function allows prepending to mutable treelists. Mutable treelists are serializable. The serialize-structs module allows the minimization of dependencies by providing only a handful of core forms. The flbit-field function allows access to the binary representation of IEEE floating-point numbers. The top-left search box in the documentation works once more. The XML reader is 2–3x faster on inputs with long CDATA and comments, and avoids some internal contract checks to obtain a 25% speedup on large documents generally. The pregexp syntax includes "X" to match a grapheme cluster, following Perl and PCRE. The read-json* and write-json* functions allow customization of the Racket representation of JSON elements, eliminating the need for a separate “translation” pass. Racket has new port I/O functions: The open-input-nowhere function creates an empty input port. The pipe-port? function makes it possible to determine whether a port is created by make-pipe. The port-file-stat function allows gathering information about the file that is the source or target of a file-stream port. A revised representation of pointers improves the performance of foreign function calls. As a result, ptr-ref and ptr-set! are substantially faster. In anticipation of the fifteenth RacketCon, the fifteenth function returns the fifteenth element of a list. Racket has an improved multi-line convention for error messages. The db library allows prepare on virtual statements. The student-t distribution is part of the math/distributions library. Expeditor supports customizing the prompt, using the #:prompt keyword argument to call-with-expeditor. There is a guide to adding internationalization for a new (human) language. Optimizations to racket/profile improve asymptotic |
| 8.15 | Nov 4, 2024 | New Release | 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 ffi/unsafe: Add `'zeroed-atomic[-interior]` allocation mode compiler/demod: Repair for Windows paths and some syntax scopes |
| 8.14 | Aug 14, 2024 | New 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. |
