Release notes for version
DrScheme version 100alpha3 is a test release for the successor of
DrScheme version 53.
In 100alpha3, DrScheme's languages and libraries are simpler,
online help is much improved, the memory footprint is smaller, and the
MacOS implementation is stable. DrScheme 100 also provides a new
expression stepper that works with the Beginner language.
- Teachers and students using DrScheme for summer classwork should
continue using DrScheme version 53.
- Teachers preparing for fall classes should test version
100alpha3. DrScheme version 100 is scheduled for release in late
July or early August.
- PLT will continue to distribute DrScheme version 53 through July
2000, at least, since version 100 is incompatible with version 53
in significant ways. However, all DrScheme users should upgrade
to version 100 as soon as possible.
- MzScheme and MrEd users should upgrade to 100alpha3. MrEd's GUI
toolbox is substantially revised and completely incompatible with
previous releases, hence the jump in version numbers.
