Lots of updates recently for Ubuntu 7.10 (Gutsy Gibbon)

I've been noticing that between desktops, laptops, and servers that there have been a lot of updates over the last week. I've seen updates for KDE packages, CUPS, Avahi, PHP, PostgreSQL, and more. Some are security related and others I believe come from the gutsy-updates repository and are just newer versions. In any case it seems like a good time to check in on any systems and update them.
