I have released the binary for the 0.4.0 version of Sanchay on Sourceforge. I will release the source code later.
The file released is a zip file containing complete Sanchay. For the next few minor releases, I will only release the jar file (and source code, if possible). The jar file in the current zip file can then be replaced with the new jar file to update your copy of Sanchay from 0.4.0 to, say, 0.4.1. For very minor changes, I will put the jar file on Box.net.
The releases should also be available from the previous location for latest builds.
