Wikipedia says 13.10 is supported until June, other sources say until July. Anybody know the exact date? It will probably take some time for me to upgrade, so I am putting it off.

I assume it is best to do a "clean upgrade," i.e., download and burn a CD or DVD, save files, install 14.04, install needed apps, etc. Any comments on this?

Can 14.04 LTS be put on a CD? Or is it too large?
