v5.3.4
43d5976b · ·Racket v5.3.4 * Extflonums (80-bit floating-point numbers) are supported on some x86/x86_64 platforms -- including Windows, and including platforms where Racket is compiled to use SSE instructions for flonum arithmetic. Thanks to Michael Filonenko. * OS X: DrRacket and all of the other apps are now signed with an official key. * Tally Maze: a new game based an enumeration of 2d mazes. * The Optimization Coach, a DrRacket plugin, has been moved from the Racket distribution to the Racket package repository. Install it with: raco pkg install optimization-coach * Redex: `define-union-language' now merges productions when languages define the same nonterminals. Thanks to William Bowman. * The `srfi/19' library is now compatible with the date structure type exported by `racket/base'.

v5.3.2
df147de3 · ·Racket v5.3.2 Core Libraries: * The new `math' library provides functions and data structures for working with numbers and collections of numbers. Functions include non-elementary (such as gamma, zeta, Lambert's W), number-theoretic (factorization, modular arithmetic), linear algebra (arithmetic, decompositions), and statistical (expected values, order statistics, binning). Data structures include arbitrary-precision bigfloats, probability distributions, and multidimensional arrays. * The new `file/untar', `file/untgz', and `file/unzip' libraries support unpacking widely used archive formats. * The new `lazy-require' form allows programs to delay the loading and instantiation of helper modules until they are needed. * The new `data/bit-vector' library provides an implementation of bit vectors (a mutable sequence of booleans) supporting popcount. * The `racket/generic' library allows the specification of default method implementations for core datatypes. * The `openssl' library can verify hostnames and use the operating system's certificate store to verify certificates. Package System: * A new package system is in beta release. This system will become Planet's successor. It differs significantly from the latter. For details, please read the documentation at http://docs.racket-lang.org/planet2/ and list your packages on the new index at https://pkg.racket-lang.org/. * The `raco test' command supports testing by collection and package, in addition to by directory and file, with the "-c" and "-p" options. Teaching Libraries: * batch-io: the read and write functions work on Unix-style standard input and output. DrRacket: * DrRacket's GUI is more responsive. * The automatic parenthesis insertion mode is improved. Scribble: * Scribble renders Markdown format files via the "--markdown" command-line flag. Example use case: Generate documentation hosted on GitHub or BitBucket. * Documentation cross-reference information is stored in an SQLite3 database, which means that SQLite3 is required for building Racket documentation on Unix/Linux machines (but SQLite3 is included in Racket distributions for Windows and Mac OS X). Using a database for cross-reference information significantly reduces the initial footprint of DrRacket, since DrRacket no longer needs to load all cross-reference information. Typed Racket: * Typed Racket programs can require `plot/typed' to draw plots. List- and vector-accepting functions accept general sequences. * Typed Racket supports Racket's delimited continuation and continuation mark operators. Redex: * Added more support for `define-judgment-form', including random generation for well-formed judgments and visualization of judgments. Deprecation: The following have been removed in this release: * the `planet' command-line tool; use `raco planet' instead. The following has been deprecated and will be removed in the August 2013 release: * the `mzlib/class100' library; use `racket/class' instead.

v5.3.1
2f4c6774 · ·Racket v5.3.1 Racket: * The `case' form dispatches on characters, fixnums, symbols, and keywords in logarithmic time. (Thanks to Jon Zeppieri.) * The new `racket/format' library provides new and improved string-formatting functions. * Logging tools include improved filtering support based on the name of a logger. A new `define-logger' form simplifies the use of named loggers. Forms such as `log-debug' now support string formatting. * The `for' forms now support `#:break' and `#:final' clauses. * The new PLTCOMPILEDROOTS environment variable configures the search path for compiled bytecode. DrRacket: * Check Syntax now summarizes the documentation (i.e., the blue boxes) for the identifier at the insertion point in the top-right corner of the definitions window. * Check Syntax now runs continuously for programs that declare their language within the source. This mode has been available for several of the past releases, but now enabled by default. * DrRacket can spell-check string constants (enable this in the Edit menu). Typed Racket: * Typed Racket interprets the Any type as a different contract. This may signal dynamic errors in some existing mixed typed/untyped programs. The normal fix is to replace a use of Any with a more specific types. * NaN is included in all of Typed Racket's floating-point types, which makes precise floating-point types easier to use. * Typed Racket supports a `cast' operation with support for higher-order types. * Typed Racket provides the `:query-type/args' and `:query-type/result' utilities to explore types at the REPL. Miscellaneous: * The `compatibility' collection provides features from Racket relatives, such as `defmacro' and mutable lists. These features are provided to ease porting code to Racket. Avoid them in modern Racket code. * Screenshots of the widgets provided by the Racket GUI library are included in the documentation. (Thanks to Diogo F. S. Ramos.) * FrTime was ported to racket lang. (Thanks to Patrick Mahoney.) Deprecation: The following has been deprecated and will be removed in the January 2013 release: * the `planet' command-line tool; use `raco planet' instead. The following has been deprecated and will be removed in the August 2013 release: * the `mzlib/class100' library; use `racket/class' instead.

v5.3
d8dc0874 · ·Racket v5.3 * Submodules are nested module declarations that can be loaded and run independently from the enclosing module. For an overview of submodules, see http://blog.racket-lang.org/2012/06/submodules.html * The futures visualizer is a graphical profiling tool for parallel programs using futures. The tool shows a detailed execution timeline depicting the migration of futures between threads, and gives detailed information about each runtime synchronization that occurred during program execution. In addition, `would-be-future' is a special type of future that always executes sequentially and records all potential barricades a regular future would encounter. * Optimization Coach (formerly Performance Report) reports information about Racket's inlining optimizations. Optimization Coach can be launched in any language through the View menu. * The new `images/flomap' library defines floating-point bitmaps and fast image processing operations on them. It is written in Typed Racket, so Typed Racket code may use it without the cost of contract checks. * The new `json' library supports parsing and generating JSON. (Originally based on Dave Herman's planet library.) * `racket/string' is extended with a set of simplified string manipulation functions that are more convenient than using regexps. `regexp-match*' and friends can now be used with new keyword arguments to return specific matched regexp group/s and gaps between matches. * The new `racket/generic' library allows generic function definitions, which dispatch to methods added to a structure type via the new `#:methods' keyword. * The `class' form supports declaring a method abstract. An abstract method prevents a class from being instantiated unless it is overridden. * The contract library comes with support for interfaces, generics, prompts, continuation-marks, and structs. * Most error messages use a new multi-line format that is more consistent with contract errors and accommodates more information. * Typed Racket supports function definitions with keyword arguments; the startup time of Typed Racket programs has been sharply reduced. * The new `ffi/com' library replaces MysterX; a compatibility `mysterx' library remains, but without ActiveX support. The new `ffi/unsafe/com' library offers a more primitive and direct way to use COM classes and methods. * There is now a very complete completion code for zsh. It is not included in the distribution though; get it at http://goo.gl/DU8JK (This script and the bash completions will be included in the standard installers in future versions.) --- DEPRECATION ---------------------------------------------------- Effective this release: - The `tex2page' and `combinator-parser' libraries have been moved from the Racket distribution to PLaneT: (require (planet plt/tex2page)) (require (planet plt/combinator-parser)) The following has been deprecated and will be removed in the January 2013 release: - the `planet' command-line tool; use `raco planet' instead. The following has been deprecated and will be removed in the August 2013 release: - the `mzlib/class100' library; use `racket/class' instead. -
