The following is a summary of the major changes in this release
|
|
from the previous one.
|
|
|
|
<h4> DrScheme </h4>
|
|
|
|
<ul>
|
|
<li>
|
|
DrScheme's fonts can now be configured through the Preferences dialog.
|
|
|
|
<li>
|
|
DrScheme's Beginner and Intermediate languages are more strict. This
|
|
provides better error messages for expressions like <TT>(1 2)</TT>
|
|
or <TT>(cond (null? l))</TT>.
|
|
|
|
<li>
|
|
A quasiquote bug has been fixed for forms like <TT>`(1 . ,3)</TT>.
|
|
|
|
<li>
|
|
The <TT>turn</TT> turtle command now turns counter-clockwise in degrees
|
|
(instead of clockwise in radians). The The <TT>turn/radians</TT> command
|
|
turns counter-clockwise in radians.
|
|
|
|
<li>
|
|
Printing has been fixed.
|
|
|
|
<li>
|
|
Output in the interactions window is much faster.
|
|
|
|
</ul>
|
|
|
|
<h4> Donkey </h4>
|
|
|
|
<ul>
|
|
<li>
|
|
The Stepper tool (Donkey) is temporarily unavailable in
|
|
release 50 and will reappear in a future release.
|
|
</ul>
|
|
|
