Subject: [PLT announcement] PLT Scheme 208 available
Date: Wed, 4 Aug 2004 18:14:34 -0400

PLT Scheme v208 is now available from

    http://download.plt-scheme.org/

* PLaneT is a package repository for PLT Scheme that is integrated
  with the module system.  For example, add
    (require (planet "csv.ss" ("neil" "csv.plt" 1 0)))
  to your program to download and use the `comma-separated values’
  package. See http://planet.plt-scheme.org/ for more packages and
  more information.

* FrTime has changed considerably since 207: multiple language levels
  (`Minimal’ includes most of MzScheme; `Standard’ also provides
  etc.ss, list.ss, math.ss, and date.ss), numerous bug fixes and
  enhancements, more interesting demos.

* ProfessorJ: the Beginner language allows initialized field
  definitions and imposes restrictions on ==.  For details, see
  doc.txt in the profj collection.

* The teachpack collection for htdp contains two additions:
  - image.ss, which defines operations for creating and manipulating
    pictures in an algebraic manner;
  - world.ss, which extends image.ss with operations for turning
    images into interactive animations.

  Note: These teachpacks fix the performance bugs we observed in
  Windows labs during TeachScheme! workshops.

  Warning: These teachpacks have slightly different interfaces than
  those use at the 2004 TeachScheme! workshops. See Help Desk for
  details.
