I published an article two years ago about using MikroTik's RSS feed to stay on top of RouterOS updates for my hAP ac3 router. While this method was sound, I'll note that I subsequently figured out how to enable automatic updates for the router, so I no longer *need* to stay on top of the updates feed.
