The release announcement sketch that I have so far is below. Please mail me new items and/or edits.
Robby and Jay -- two pending items: ? New racket/contract/combinator library and some contract module reorganization (this is in 21cbd9ad) ? New `scriblib/bibtex' that can read bibliographic databases in bibtex format. ---------------------------------------------------------------------- * The download page includes 64-bit installers for Windows, Mac OS X, and two Debian flavors. * Racket now includes a new `racket/place' library to support parallelism, complementing `racket/future'. Racket's parallel build process is now based on places instead of multiple OS processes. Places support share-nothing parallelism and message-passing communication. Compared to futures, places are heavyweight, but they have a simpler performance model. * The syntax-certificate system has been replaced by a syntax-taint system. Both certificates and taints were designed to protect otherwise inaccessible bindings from abuse when they appear in macro expansions. Taints are simpler and lighter, and the switch closes known holes in the certificate system. Macros that are not implemented with `syntax-rules' or `define-syntax-rule', however, must explicitly use `syntax-protect' to protect their expansions from abuse. * The `net/url' library supports HTTPS connections, but beware that by default all sites are accepted (equivalent to ignoring a browser's warnings about untrusted certificates). * The `for' forms now support an `#:unless' clause, and a nonnegative integer can be used as a sequence. The new `compose1' function creates single-valued composition functions. The `racket/function' library now provides `identity', `thunk', and `thunk*'. * Error messages in the student languages use a smaller vocabulary and consistent phrasings. If you maintain curriculum material or teachpacks then please consider updating. See the "Error Message Composition Guidelines" section in the documentation for details. * Typed Racket: almost all core Racket data structures and operations are now accessible in Typed Racket (most of this work is due to prolific contributor Eric Dobson). The performance of the typechecker has been significantly improved. * The license has been clarified: we now use LGPLv2.1 uniformly. (The license file used to specify LGPLv2, contrary to the download pages.) ---------------------------------------------------------------------- -- ((lambda (x) (x x)) (lambda (x) (x x))) Eli Barzilay: http://barzilay.org/ Maze is Life! _________________________________________________ For list-related administrative tasks: http://lists.racket-lang.org/listinfo/dev
