 - gocql now refreshes the entire ring when it receives a topology change event and
   when control connection is re-connected.
   This simplifies code managing ring state. (#1680)
 - Supported versions of Cassandra that we test against are now 4.0.x and 4.1.x. (#1685)
+- Default HostDialer now uses already-resolved connect address instead of hostname when establishing TCP connections (#1683).
