From: Wolfram Research on
Wolfram|Alpha, our new computational knowledge engine, is
developed and deployed entirely in webMathematica. webMathematica
makes the calculations performed by Wolfram|Alpha possible by
allowing users to tap into Mathematica's computational and
graphic abilities without having Mathematica experience or
installing it locally.

Now you can get webMathematica 3, the version that drives
Wolfram|Alpha.

With webMathematica 3, web users can access the latest features
of Mathematica 6 and 7, including image processing and new
classes of special functions. In addition, sliders and other GUI
features can be automatically built with a single command, just
as in a Mathematica notebook, so you can easily include
interactive features on your website.

webMathematica 3 also provides development and performance
advantages by letting you do the following:
* Write REST and SOAP web services that use Mathematica
* Integrate with Wolfram Workbench to debug Mathematica code as
it runs in the server
* Improve startup time and reliability with new configuration
tools and code to limit and monitor running time and memory use
* Integrate with standard server applications
* Much more

will receive an email in the next few days with instructions on
how to download their free upgrades.
