PLT Release Notes</h2>
|
|
|
|
<p>
|
|
|
|
<b>Current Release</b>:<tt> </tt> 53 <br>
|
|
<b>Release Date</b>:<tt> </tt> July 25, 1998.
|
|
|
|
<p>
|
|
|
|
|
|
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.
|
|
|
|
<h2> The Future </h2>
|
|
|
|
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.
|
|
|
|
<P>
|
|
|
|
<h2>Changes</h2>
|
|
|
|
<ul>
|
|
<li>DrScheme, MrEd, and MzScheme have
|
|
significantly improved performance on PowerPC Macintoshes.
|
|
</ul>
|
|
|
|
See the HISTORY files in notes/drscheme descriptions of other changes and
|
|
bug fixes for DrScheme.
|
|
|
|
<P>
|
|
|
|
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.
