I see two good reasons for including Mozilla 1.0 to Skipjack, if the schedule
allows it. (It hasn't been released yet but should be soon.)
First, the "lock icon bug" http://bugzilla.mozilla.org/show_bug.cgi?id=101723
was fixed after 0.9.9. It is kind of a security issue, although not critical.
However It did gain around 80 duplicates in Bugzilla before it was fixed.
Secondly, there was a redesign of the menues after 0.9.9. Many items changed
places and so on.
Therefore, wouldn't it be bad to accustom passive users to an obsolete design?
1.0 hasn't been released. When it is I'll certainly consider doing an errata
