PLT Scheme version 371 is now available from


This is mostly a bug-fix release.


 * 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.
