## 0.5.0 (Unreleased)
FEATURES:
* Key rotation support for gossip layer. This allows the `encrypt` key
to be changed globally. See "keyring" command. [GH-336]
* Options to join the WAN pool on start (`start_join_wan`, `retry_join_wan` ) [GH-477]
* Optional HTTPS interface [GH-478]
* Ephemeral keys via "delete" session behavior. This allows keys to be deleted when
a session is invalidated instead of having the lock released. Adds new "Behavior"
field to Session which is configurable. [GH-487]
* Reverse DNS lookups via PTR for IPv4 and IPv6 [GH-475]
* API added checks and services are persisted. This means services and
checks will survive a crash or restart. [GH-497]
* ACLs can now protect service registration. Users in blacklist mode should
allow registrations before upgrading to prevent a service disruption. [GH-506] [GH-465]
* Sessions support a heartbeat failure detector via use of TTLs. This adds a new
"TTL" field to Sessions and a `/v1/session/renew` endpoint. Heartbeats act like a
failure detector (health check), but are managed by the servers. [GH-524] [GH-172]
* Support for service specific IP addresses. This allows the service to advertise an
address that is different from the agent. [GH-229] [GH-570]
* Support KV Delete with Check-And-Set [GH-589]
* Merge `armon/consul-api` into `api` as official Go client.

* Added new "consul lock" command for simple highly-available deployments.
This lets Consul manage the leader election and easily handle N+1 deployments
without the applications being Consul aware. [GH-619]
* Multiple checks can be associated with a service [GH-591] [GH-230]

use tokens which can be restricted to (read, write, deny) permissions
using longest-prefix matches.
* Watch mechanisms added to invoke a handler when data changes in consul.
Used with the `consul watch` command, or by specifying `watches` in
an agent configuration.
* Event system added to support custom user events. Events are fired using
the `consul event` command. They are handled using a standard watch.

instances mediated through Consul.
