The TYPO3 CMS version 4.5, released in January 2011, was the first version having the label “Long Term Support” attached to it. After 4 years of support, we hope that everybody has upgraded to our latest version TYPO3 CMS 6.2 LTS (or to CMS 7 which has been released meanwhile). The LTS support is going to end on March 31st, 2015, which already includes only high priority and critical fixes related to browser and security. Still, version 4.5 is among the most popular TYPO3 versions on the web.
