ah...
here it is...
The bad news is that we still do not have an ETA for the
testing-security autobuilders to be functional. This continues to be
the major blocker for proceeding with the freeze; we would /like/ to
have security support in place for sarge before encouraging widespread
upgrade woody->sarge upgrade testing, but we /need/ to have it in place
before releasing, so it would be unwise to try to freeze the rest of the
archive without any confirmed schedule for the last stages of the
release.
hmmm... and that message is over a month old... perhaps not so recent after all...
