Fedora 9

Fedora 9 was released March 13, 2008. This release has many new innovations and features, and living up to its reputation of bleeding edge. Although the bleeding edge status is nice, it does come at somewhat of a cost. Fedora 9 ships with the newest X.org server that is incompatible with both ATI and NVidia's binary only drivers.

Some of the more exciting features (for me anyway) are:

• Free IPA
• Gvfs
• Firefox 3
• LTSP
• USB Booting and Persistance

These are just a few, but definitely worthwhile features jammed packed into Fedora 9.
