2003 MSN Messenger blocks Trillian

Users of Microsoft's free Web-based MSN Messenger and its Windows XP-based Windows Messenger will need to upgrade their software to a newer version or be shut out of the service, the software giant said Wednesday. MSN Messenger users will need to upgrade to version 5.0 of higher; Windows Messengers customers will need to upgrade to version 4.7.2009 or higher; and consumers with MSN Messenger for Mac OS X will have to use version 3.5 or higher. The last MSN Messenger to be released was version 6. According to Microsoft spokesman Sean Sundwall, "Security issues that could be posed (on older versions) require us to force an upgrade." He declined to detail the security issue, saying disclosure would "put customers at undue risk."
