Looks like we failed somewhere to get the word out about
devel-announce-list widely enough. It's a very low volume list meant
for important announcements. Granted, as aes mentioned, the general
discussion happened on gnome-hackers but for those who'd prefer to
just get the big announcements, the postponement[1] and new date[2] of
the SVN migration were both announced to devel-announce-list.
