The release announcement sketch that I have so far is below. Please mail me new items and/or edits. ---------------------------------------------------------------------- PLT Scheme version 4.2 is now available from
http://plt-scheme.org/ * New in `scheme/base': `hash-has-key?', `hash-ref!', `in-sequences', `in-cycle' and in `scheme': `count', `make-list' (from `scheme/list') `const' (from `scheme/function') * New statistical profiler, core and text interface for now * Scheme-implemented editor classes * on-demand instantiation of module phases * web-server: Native continuations in serial language, soft state, and typos. I'm not sure that these should have an item: * make-rename-transformer => free-identifier=? (v5.1.5.2) * free-id=? propagation through module exports; add 'not-free-identifier=? syntax property to disable free-id=? propagation; add prop:rename-transformer and prop:set-transformer; fix scheme/local so that local syntax bindings are visible to later definitions (v4.1.5.3) * per-thread cpu timing [Note that mirror sites can take a while to catch up with the new downloads.] Feedback Welcome, ---------------------------------------------------------------------- -- ((lambda (x) (x x)) (lambda (x) (x x))) Eli Barzilay: http://www.barzilay.org/ Maze is Life! _________________________________________________ For list-related administrative tasks: http://list.cs.brown.edu/mailman/listinfo/plt-dev
