_ In the torrent for v.5.3.1, the torrent's comment mentions V.5.3.0. Of course this is not critical; I mention it just for reference (in case someone might confuse the torrent or might doubt whether the torrent is the official one) so to avoid this quirk in the future.
It seems your manual TODO list for releases might benefit from some additional scripting
_ Some of the files under "tools/win32/" have Unix-style end-lines, instead of Windows-style end-lines.
_ In ubcd2usb.cmd, the VOLUME_ID is set to UBCD529, instead of UBCD531. This step should probably be in your TODO list for releases too (either manual or scripted).
_ What about http://www.ultimatebootcd.com/forums/viewtopic.php?p=25379#p25379
