UPDATE January 13, 13:50 CET:
The Antivirus and antispyware scanner module 1569 is now available for pre-release users, this module enables the yellow alerts in v5 Endpoint products.
Following the yellow "product outdated" alerts on more recent (v6+) products, we will show the same alert on v5 Endpoints as well, starting with pre-release users on January 13 and general public on January 20. Please, guide the customers who contact you to upgrade according to the scenarios laid out at https://support-eol.eset.com/
Later this month, we also plan to switch the current v6+ Endpoints from yellow to red alerts. We will share more information once an exact date is set.
