 this is not important, since the abstraction should be masked by Consul. It can be useful
 however as a developer to understand how this library is leveraged.

+## Lifeguard Enhancements
+
+Consul's Gossip Protocol, shared with HashiCorp's Serf, forms the basis of its powerful
+distributed failure detector. Unfortunately, the algorithm on which it is based makes an
+assumption that the local node is healthy in the sense that soft real-time processing of
+packets is possible. In Consul versions prior to 0.7, this can sometimes manifest in a
+severely degraded node falsely accusing others of being failed, causing occasional flaps
+in the `serfHealth` check status for one or more healthy nodes. Consul 0.7 adds two Serf
+Lifeguard enhancements to this algorithm to help performance in the presence of degraded
+nodes.

+Please see [Serf's gossip protocol guide](https://www.serf.io/docs/internals/gossip.html#lifeguard)
+for more details.
