Syslog over TCP — the built-in Log collector now accepts syslog over TCP in addition to UDP (port 5514 for both). Useful when UDP is blocked in the path or when you want guaranteed delivery. RouterOS 7.x has Remote Log Protocol: TCP natively — just pick TCP in the Setup Guide on the Logs page and the generated snippet includes remote-log-protocol=tcp.
Port mapping — if you want TCP syslog reachable from outside the container, add 5514:5514/tcp to your docker-compose.yml (alongside the existing 5514:5514/udp). UDP-only setups keep working unchanged.
