[DSA-1975-1] Security Support for Debian 4.0 to be discontinued on February 15th


For anyone still on Debian 4.0, now is a good time to work on a
migration plan to Debian 5.0. Debian will stop releasing security
updates after February 15th for 4.0.

This is also a good time for Ubuntu users to check their distribution
for similar announcements. Ubuntu is based on Debian.
