Today MathSoft announced the upcoming availability of two versions of
S-PLUS--S-PLUS 4.5 Professional for Windows and S-PLUS 4.5 Standard for
Windows. With these releases we have renamed the full product S-PLUS 4.5
Professional and created a new edition called S-PLUS Standard. The standard
edition has all of the user interface functionality of S-PLUS without access
to the command line and is available at a lower price. In North America,
S-PLUS 4.5 Professional is available now and the Standard edition will be
available in early June.

S-PLUS Windows users who have Software Support and Subscription Plans
(current maintenance) will automatically receive a new S-PLUS 4.5
Professional CD and accompanying booklet describing the new features. These
upgrades will begin shipping the week of May 11th. The upgrade is not
available for downloading from the web due to the size of the files.

S-PLUS 4.5 provides a wealth of new functionality in the following categories:

Ease-of-use enhancements
