I was working on finishing the version 1.09, but there were major architectural problems that are needed to be rewritten. Hence, I've decided to redesign the whole user interface and implement all the missing features.
Since it will take a long time, I've uploaded the latest binaries of 1.09 to the project web site where you can download from and give it a try. Note, it's not a final version but a slight preview of NClass 2.0.
