End of Life date for Firewall V3.14 ??

Ok I see EricJH has posted this on another thread

https://forums.comodo.com/install-setup-configuration-help-cis/reasons-to-upgrade-from-3-to-4-t59129.0.html;msg425048#msg425048

so I suppose the Question is now - For how long am I secure using Firewall V 3.14 ??
