+      body: >
+        This commit does two related things:
+
+
+        * We make the poll interval a random time between 0.5 and 1.5 times the
+        configured interval.
+
+        * We introduce the BALENA_SUPERVISOR_INSTANT_UPDATE_TRIGGER
+        configuration variable, that defaults to true. If this variable is set
+
+        to false, then calls to /v1/update are ignored, and on startup the
+        supervisor waits for a poll interval before getting the target state.
+
+
+        This will help especially on cases where there's a large number of
+        devices on a single network. By disabling instant updates and setting a
+        large
+
+        poll interval, we can now achieve a sitation where not all devices apply
+        an update at the same time, which can help avoid
+
+        overwhelming the network.
