Today, January 27, 2014, is the day that 13.04 Raring reached End of Life.

While this means **new** questions (stressing the **new**) about 13.04 are off topic, older questions that were around before the EOL date should not be closed or deleted.

**This is done here with the consensus of the moderators which is that the primary reason for is not supporting EOL releases is because those versions no longer receive updates or security support, and you should not use those versions because of the lack of security updates.  This is not just my opinion, but has reached some consensus here on meta in other threads.**

Also note that 13.10 is still supported. as is 12.10.
