+ * [Issue #427](https://github.com/fabiolb/fabio/issues/427): Fabio does not remove service when one of the registered health-checks fail
+
+   If a service has more than one health check then the behavior in whether the
+   service is available differs between Consul and Fabio. Consul requires that
+   all health checks for a service need to pass in order to return a positive
+   DNS result. Fabio requires only one of the health checks to pass.
+
+   A new config option `registry.consul.checksRequired` has been added which
+   defaults to the current fabio behavior of `one` passing health check for the
+   service to be added to the routing table. To make fabio behave like Consul
+   you can set the option to `all`.
+
+   Fabio will make `all` the default as of version 1.6.
+
+   Thanks to (@systemfreund)[https://github.com/systemfreund] for the patch.
