## 0.7.0 (UNRELEASED)
IMPROVEMENTS:
* Consul agents will now periodically reconnect to available Consul servers
in order to redistribute their RPC query load. Consul clients will, by
default, attempt to establish a new connection every 120s to 180s unless
the size of the cluster is sufficiently large. The rate at which agents
begin to query new servers is proportional to the size of the Consul
cluster (servers should never receive more than 64 new connections per
second per Consul server as a result of rebalancing). Clusters in stable
environments who use `allow_stale` should see a more even distribution of
query load across all of their Consul servers. [GH-1743]
