Update to Racket 5.3.2
Changes in 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.
Changes in 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.

Log message:
lang/racket-textual: pkglint cleanup
Admittedly most of this cleanup is petty cosmetic stuff, but there are
so many warnings that real problems are obscured such as the direct use
of $LOCALBASE. Also the use of parentheses instead of curly braces
caused several fake errors about not finding patches.

Update to Racket 5.3
Changes in Racket 5.3
* 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.

Log message:
Update to Racket 5.2.1
Changes in Racket 5.2.1
* Performance improvements include the use of epoll()/kqueue()
instead of select() for the Racket thread scheduler, cross-module
inlining of small functions, and the use of SSE instead of x87 for
JIT-compiled floating-point operations on platforms where SSE is
always available (including x86_64 platforms). A related change
is the interning of literal numbers, strings, byte strings,
characters, and regexps that appear in code and syntax objects.
* DrRacket uses a set of composable ray-traced icons available from
the new `images' library collection.
* Typed Racket's `typecheck-fail' form allows macro creators to
customize the error messages that Typed Racket produces. This is
especially useful when creating pattern matching macros.
* The performance of Redex's matcher has been substantially
improved; depending on the model you should see improvements
between 2x and 50x in the time it takes to reduce terms.
* Plots look nicer and are more correct at very small and very large
scales. New features include customizable dual axis ticks and
transforms (e.g., log axes, date and currency ticks, axis interval
collapse and stretch), stacked histograms, and 3D vector fields.
The legacy `fit' function and libfit have been removed.
* The `2htdp/universe' library's `big-bang' form supports an
experimental game pad key handler.
* The `db' library now supports nested transactions and PostgreSQL
arrays. Bugs involving MySQL authentication and memory corruption
in the SQLite bindings have been fixed.
* The Macro Stepper tool in DrRacket no longer executes a program
after expanding it.
* In the DMdA teaching languages, infinite recursive signatures
("streams", for example) with no intervening `mixed' are now
supported, and the signatures of record definitions without fields
now have generators for use with `property'.
* MysterX's ActiveX support is deprecated and will be removed in the
next release. MysterX's core COM functionality will become
deprecated in the next release, but COM functionality will be
supported for the foreseeable future as a compatibility layer over
a forthcoming `ffi/com' library.
