From Yahoo! Messener Blog
A couple of months ago, we told you that we would be retiring Yahoo! Messenger versions 6.0 through 7.5 this Fall. The date for retirement has been set for September 30, 2009.
This means that if you are currently using a version of Yahoo! Messenger that is below 8.0, you will no longer be able to sign in and use it after September 30.
If you are using a version that is set to retire, you have several options for continuing to use Yahoo! Messenger..

Does anybody even use Yahoo! Messenger 6.0 through 7.5 anymore? Haha.
