The support languages for the "Programming Languages: Application and
Interpretation" textbook by Shriram Krishnamurthi are now part of PLT
Scheme. In addition, a random mutator generator for testing garbage
collectors was added by Robby Findler.

The Scheme-implemented bytecode reader, writer, and decompiler is now
more compatible with
the C-implemented bytecode reader and writer.
