The release announcement sketch that I have so far is below, it's closer to proper text, but more input is needed. Note also the items that I don't know if it's worth mentioning or not. Please mail me new items and/or edits.
---------------------------------------------------------------------- PLT Scheme version 4.2 is now available from http://plt-scheme.org/ * A substantial part of MrEd (the editor classes) is now implemented in Scheme. [Need to say something about thousands of lines that were migrated etc.] * On-demand instantiation of module phases. [I don't know how to summarize that effectively.] * A new statistical profiler is now available, currently it supports only a textual output, and a GUI interface will be added and integrated into DrScheme. (See the "profiler" manual for more information.) * The `world' teachpack is now deprecated; its replacement (`universe') has a new interface, using strings instead of symbols and chars. * Web-server: Native continuations in serial language, soft state, and typos. * The stepper can now jump to a selected program expression. * New in `scheme/base': `hash-has-key?', `hash-ref!', `in-sequences', `in-cycle'; and new in `scheme': `count', `make-list' (from `scheme/list'), `const' (from `scheme/function') 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 ---------------------------------------------------------------------- -- ((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
