Download site is the same, I'm working on getting a larger pipe for it so I can put it somewhere else (possibly tomorrow).
Improvements are minimal, but this one allows people to create their own plug-ins as we've stated. There's a sample plug in up there, in a zip file.
Please ask questions, I'm willing to help!
Also let me know if the download fails, the old version is up there two just to keep things cool in case I screwed something up. I believe the MSI will work, but I'm not 100% positive because the two machines I've got to test it on had older versions, and the speech sdk on it!
This is very much a beta!
