Insightful Corporation Announces S-PLUS® 8 Upgrade Program

Maintenance customers for S-PLUS 6.2 and 7 Professional Developer versions can upgrade to S-PLUS 8 Enterprise Developer for free

SEATTLE - May 21, 2007 -

Insightful Corporation (NASDAQ: IFUL), a leading provider of predictive analytics and reporting solutions, announced today a free upgrade for maintenance customers of Insightful’s S-PLUS® 6.2 or 7 Professional Developer, to its S-PLUS 8 Enterprise Developer.

"We wanted to find the best way to say thank you to our loyal customers for 20 years of support and believe that delivering our most comprehensive development platform ever to the widest possible audience was a great start,” commented Jeff Coombs, president and CEO of Insightful. He added, “By waiving the software upgrade fee we hope to encourage as many of our users as possible to take advantage of the development breakthroughs available in S-PLUS 8.”

NEW FEATURES IN S-PLUS 8.0

* Workbench: This feature, originally introduced in S-PLUS 7, has been further enhanced in the 8 release. Programmers can speed the development of applications for competitive advantage by using the new debugger and profiler. The interactive debugger allows users to quickly debug S-PLUS code from within the S-PLUS workbench, and includes modern debugging tools such as step debugging and breakpoints. The profiler provides an environment for writing and developing functions in S-PLUS that allow profiling of time and memory allocation within S-PLUS tasks. The user can now optimize the code’s execution by evaluating where bottlenecks exist.
* Graphics enhancements: S-PLUS is already a leading platform for graphics creation and delivery. In version 8, Insightful has included a larger and normalized color palette as well as providing simplified code necessary to deliver complex graphs and charts. Whether a developer is creating graphics for submission to the FDA or distribution to a group of portfolio managers at an investment bank, S-PLUS 8 Enterprise Developer makes this task easier and more time efficient.
* S-PLUS Package System: With already 25 published packages available, S-PLUS 8 Enterprise Developer provides a convenient framework for creating and distributing libraries for S-PLUS and for converting packages written in R (S-PLUS’s open-source cousin) for use in S-PLUS.
* S language extensions: Over one hundred new functions have been added in order to support the graphics enhancements, the S-PLUS Package System and to augment compatibility with R. Types of functions that have been added include math, character, file manipulation and string manipulation.
