I'm running 4.5.3, which I upgraded from 3.1.4 on a default CentOS 4 desktop install. I'm missing apps in my admin-console's download section. The only apps listed are:

Migration Wizard for Exchange
Migration Wizard for Domino
ZCS Migration Wizard for GroupWise
PST Import Wizard
Zimbra Toaster

The ones I know aren't there are the Outlook Connector and the Apple iCal Connector. Which other files should I have, and where else can I find them?
