The next sentence in the "Upgrading" section of the announcement:also
has a problem, I think:

http://drupal.org/drupal-5.2
quote:"If you are upgrading from Drupal 4.6.x or below, please consult
the relevant release announcements."

I don't understand. We are now reading the 5.2+4.7.7 announcement.
Which are the "relevant release announcements" for upgrading from
4.6.x? (And if there is such a thing, where).
