Blog updates on RPi Grafana Home Page

Im sure this is my ignorance, but how is the “blog” on my Grafana home page being updated on my RPi hosting grafana? The URL is the IP and port. Shouldn’t I be completely disconnected from anything after the date I installed it? What is pushing these updates? Not that I care, but just curious how grafana is sending new info to be displayed on my private IP and port after a 1 time install.

Again, not complaining, just curious.
