PLT Scheme v371

PLT Scheme version 371 is now available from http://download.plt-scheme.org/ This is mostly a bug-fix release. Changes:

  • The debugger now works across multiple files and supports "step over" and "step out" operations.
  • HtDP teachpacks: the world.ss teachpack now exports two add-line functions: one from image.ss and one for adding lines to scenes.
  • ProfessorJ now includes a language level between Intermediate and Advanced, Intermediate + access, that includes all of Intermediate and introduces access modifiers and overloading. The language manuals contain the complete details.

Feedback Welcome.
