I have posted milestone 5. You can get it here(https://nbpython.dev.java.net/servlets/ProjectDocumentList?folderID=9641&expandFolder=9641&folderID=0)
Just a note, Milestone 5 has a completely new project system. so any project created before Milestone 5 will not open. My recomendation is that you create the project with a new name and then copy the files from the old source directory to the new source directory. Then everything will be ok.
