 IMPROVEMENTS:
 
-* agent: Retry Join for Amazon AWS, Microsoft Azure, Google Cloud, and Softlayer is now handled through the https://github.com/hashicorp/go-discover library. With this all `-retry-join-{ec2,azure,gce}-*` parameters have been deprecated in favor of a unified configuration. See [`-retry-join`](https://www.consul.io/docs/agent/options.html#_retry_join) for details. [GH-3282,GH-3351]
+* agent: Retry Join for Amazon AWS, Microsoft Azure, Google Cloud, and (new) Softlayer is now handled through the https://github.com/hashicorp/go-discover library. With this all `-retry-join-{ec2,azure,gce}-*` parameters have been deprecated in favor of a unified configuration. See [`-retry-join`](https://www.consul.io/docs/agent/options.html#_retry_join) for details. [GH-3282,GH-3351]
 * cli: Added a `-child-exit-code` option to `consul lock` so that it propagates an error code of 2 if the child process exits with an error. [GH-947]
 * docs: Added a new [Geo Failover Guide](https://www.consul.io/docs/guides/geo-failover.html) showing how to use prepared queries to implement geo failover policies for services. [GH-3328]
+* docs: Added a new [Consul with Containers Guide](https://www.consul.io/docs/guides/consul-containers.html) showing critical aspects of operating a Consul cluster that's run inside containers. [GH-3347]
 * server: Added a `RemoveEmptyTags` option to prepared query templates which will strip out any empty strings in the tags list before executing a query. This is useful when interpolating into tags in a way where the tag is optional, and where searching for an empty tag would yield no results from the query. [GH-2151]
 * server: Implemented a much faster recursive delete algorithm for the KV store. It has been bench-marked to be up to 100X faster on recursive deletes that affect millions of keys. [GH-1278, GH-3313]
