Well, this release is mostly an UI update. There is a major functionality update of this new release is the "Advanced" settings. If you are using the default mode, it will work as it was working previously.
With advanced mode, one need to change two things. One is the "raytrace.as" which comes budled with this application. Inside this file one has to put the connection name. This name could be any string, it could be your project name, version name or your name, but then remember this name so as to put the same name in advanced setting text input (thats the second setting). After that its as usual process.
The release version can be found here for direct download and use. The source code is up in github.
