MikroTik heeft versie 7.21.4 van RouterOS uitgebracht, een besturingssysteem dat zich richt op het uitvoeren van routertaken en meer. Denk daarbij natuurlijk aan het routeren van netwerkverkeer, maar ook aan bandbreedtemanagement, een firewall, het aansturen van draadlozeaccesspoints, een hotspotgateway en een vpn-server. Het kan zowel op de hardware van MikroTik als op x86- of virtuele machines zijn werk doen. Voor het gebruik is een licentie nodig, die bij de aankoop van MikroTik-hardware is inbegrepen. De changelog voor deze uitgave kan hieronder worden gevonden.
