CloudLinux had not announced plans for Extended Lifecycle Support (ELS) specifically for CloudLinux 7. However, CloudLinux typically provides updates and support for their operating systems for a period of time after the end of the regular support cycle.
For the most accurate and up-to-date information regarding CloudLinux 7's Extended Lifecycle Support or any announcements related to it, I recommend checking directly with CloudLinux's official website or contacting their support team. They will be able to provide you with the latest information on support and updates for CloudLinux 7.
