I have pushed out a SYSLINUX 3.55-pre1. The only difference from 3.54 is that 3.55-pre1 obsoletes the use of the magic cookie option 208, in accordance with RFC 5071 (http://www.rfc-editor.org/rfc/rfc5071.txt). I don't consider this a significant enough change to make another release over, but at least it is out there if people want to experiment with it. I would really like to know if it causes problems in real-life netboot environments. -hpa
