[keycloak-user] Is Keycloak 2.5.4 EOL or unsupported?

I’m not finding an easy way to tell if Keycloak 2.5.4 is EOL or unsupported. Looking at the Github releases this version was released in Feb 2017. That in itself doesn’t tell me if the version is unsupported or contains security vulnerabilities. Can someone from Redhat please provide some information regarding the status of this version. Thanks in advance.
