From: Eli Barzilay <firstname.lastname@example.org> To: email@example.com, firstname.lastname@example.org 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.
