[plt-dev] Release Announcement for v4.2.5 -- tiny version

From: Eli Barzilay (eli at barzilay.org)
Date: Fri Apr 2 15:55:43 EDT 2010

To experiment with adding this to the release procedure, this is the
tiny version for freshmeat that I have (and is typical for how I edit
these things).  Please avoid telling me how this is very bad --
instead, revise and reply.  (If this works out, I'll add it to the
release procedure.)

Support for multi-core parallelism via futures -- see
http://tinyurl.com/futuresguide; includes the schemeunit testing
framework (with a gui frontend); support for PLAI languages; Russian
and Ukranian translations added; Typed Scheme extended: generate
predicates from types, can have typed regions in untyped modules;
contract combinators for the class system; improved language dialog
uses "#lang" by default.  See http://blog.plt-scheme.org/ for the full
release announcement.
