PLT Release Notes
Current Release: 53
Release Date: July 25, 1998.
DrScheme v53 is primarily a bug-fix release. Many of the fixes
are a result of the TeachScheme! 1998 Workshop held at
Rice University.
This note summarizes the major differences between this release
and DrScheme v52.
The Future
PLT intends to conduct a major release by the end of this year or early
next year. The changes will directly affect users of MrEd, the graphical
toolbox. Please expect deletions of features, additions, and a few
modifications. DrScheme will migrate to a graphical multi-module
environment. This change should not affect beginners or teachers.
Changes
- DrScheme, MrEd, and MzScheme have
significantly improved performance on PowerPC Macintoshes.
See the HISTORY files in notes/drscheme descriptions of other changes and
bug fixes for DrScheme.
MzScheme and MrEd users should look at the HISTORY
files in notes/mzscheme and notes/mred for detailed descriptions of
changes and bug fixes for those applications.
