All the versions of MDJ 2007.12.20 that were just released are signed properly. (Tables like “Table 1” still take way too much time; it delayed yesterday’s issue by several hours.)
Unfortunately, they’re all digitally signed with a masthead that says “Previous issue: 2007.12.02”. It was MDJ 2007.12.03, of course. Lots of things that used to be more automated currently are not, but we’re working on it.
