     Fixes the JSON RPC backend potentially hanging on inability to connect
-    to a conductor. The default timeout is now 15 seconds and 2 retries are
-    made. These values can be adjusted via the configuration options
+    to a conductor. The default timeout is now 120 seconds. The timeout and
+    a number of retries can be adjusted via the configuration options
     ``[json_rpc]timeout`` and ``[json_rpc]connect_retries`` accordingly.
