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 <a href="http://docs.racket-lang.org/planet2/" target="_blank">http://docs.racket-lang.org/planet2/</a> and list your packages on the new index at <a href="https://pkg.racket-lang.org/" target="_blank">https://pkg.racket-lang.org/</a>. * 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.
