Re-validate the 8.0 export against the Zabbix 8.0.0 release and drop references to the development build. - Import the 8.0 export into Zabbix 8.0.0 and link it to a test host. - Mark 8.0 LTS as supported in the README and version policy. - Remove the alpine-trunk fallback note now that 8.0 images exist. - Run the CI import test as a 7.0/8.0 matrix with distinct project names and host ports so parallel jobs do not collide.
