IBM's WebSphere sMash development team has made V126.96.36.199 of the product available for download. V188.8.131.52 as well as our latest experimental drivers are freely available for download from http://www.projectzero.org . If you're not familiar with sMash you should give it a try. It's a development and runtime environment that's intended to revolutionize creation of dynamic, RESTful web apps based on Web 2.0 technologies & dynamic scripting languages (PHP & Groovy).
V184.108.40.206 builds on our V1.1 release and adds PHP performance improvements, a new PHP to Groovy bridge (call Groovy classes from PHP), and a number of enhancements requested in our Project Zero community. For example supporting Zero forms in Assemble Flows, supporting PHP in Assemble Flows, and explicit HTTP Cookie support in our Connection API.
