From release notes for FC5T3 (web)

[Jim Cornette]

Just posting a link from the upcoming Fedora version 5 notes. (FC5T3 as 
of now)
The changes might be good to know for a user to make a decision when FC5 
is released as to how to upgrade / install.

http://fedora.redhat.com/docs/release-notes/fc5/test3-latest-en/#sn-PackageChanges

Major changes for people installing are xen, screensavers, menu 
reconfiguration, a GUI search tool, a few applications that use mono, no 
up2date program, a new package manager and GUI front end to yum.

Everything installs are no longer possible. The major components are now 
in groups and part of the optional packages can be selected or not 
selected through check marks. Some packages that were selectable in the 
past may not be selectable from the menus though they are on the install 
media.

How usb devices are managed and items like names for the mounted media 
using volume names for the mount points is different.

Suspend is available from the menus if your computer is capable of 
suspending. Hibernate is not a menu choice but works as well from script 
pm-hibernate.

I did not notice any major application changes from FC4 to FC5.

Jim
