After receiving a file from MTeng I had built and released 2.2.1.5. As MTeng has not yet checked in this file, and there is another bug on the 2.2.1.5 list, I do not consider 2.2.1.5 done yet. I have built and put a label down but this is sort of an unofficial build.
Also worked ag getting XDMCP running on sonlinux again. Still not working right.
