 	<h1>0.13.0 Released</h1>

 	<p>The latest Apache Aurora release, 0.13.0, is now available for
 <a href="http://aurora.apache.org/downloads/">download</a>. Here are some highlights in this release:</p>

 <ul>
 <li>Upgraded Mesos to 0.26.0</li>
 <li>Added a new health endpoint (/leaderhealth) which can be used for load balancer health
 checks to always forward requests to the leading scheduler.</li>
 <li>Added a new <code>aurora job add</code> client command to scale out an existing job.</li>
 <li>Upgraded the scheduler ZooKeeper client from 3.4.6 to 3.4.8.</li>
 <li>Added support for dedicated constraints not exclusive to a particular role.
 See <a href="/documentation/0.13.0/features/constraints#dedicated-attribute">here</a> for more details.</li>
 <li>Added a new argument <code>--announcer-hostname</code> to thermos executor to override hostname in service
 registry endpoint. See <a href="/documentation/0.13.0/reference/configuration#announcer-objects">here</a> for details.</li>
 <li>Descheduling a cron job that was not actually scheduled will no longer return an error.</li>
 <li>Added a new argument <code>-thermos_home_in_sandbox</code> to the scheduler for optionally changing
 HOME to the sandbox during thermos executor/runner execution. This is useful in cases
 where the root filesystem inside of the container is read-only, as it moves PEX extraction into
 the sandbox. See <a href="/documentation/0.13.0/operations/configuration#docker-containers">here</a>
 for more detail.</li>
 <li>Support for ZooKeeper authentication in the executor announcer. See
 <a href="/documentation/0.13.0/operations/security#announcer-authentication">here</a> for details.</li>
 <li>Scheduler H2 in-memory database is now using
 <a href="http://www.h2database.com/html/mvstore.html">MVStore</a>
 In addition, scheduler thrift snapshots are now supporting full DB dumps for faster restarts.</li>
 <li>Added scheduler argument <code>-require_docker_use_executor</code> that indicates whether the scheduler
 should accept tasks that use the Docker containerizer without an executor (experimental).</li>
 <li>Jobs referencing invalid tier name will be rejected by the scheduler.</li>
 <li>Added a new scheduler argument <code>--populate_discovery_info</code>. If set to true, Aurora will start
 to populate DiscoveryInfo field on TaskInfo of Mesos. This could be used for alternative
 service discovery solution like Mesos-DNS.</li>
 <li>Added support for automatic schema upgrades and downgrades when restoring a snapshot that contains
 a DB dump.</li>
 </ul>

 <p>Deprecations and removals:</p>

 <ul>
 <li>Removed deprecated (now redundant) fields:

 <ul>
 <li><code>Identity.role</code></li>
 <li><code>TaskConfig.environment</code></li>
 <li><code>TaskConfig.jobName</code></li>
 <li><code>TaskQuery.owner</code></li>
 </ul></li>
 <li>Removed deprecated <code>AddInstancesConfig</code> parameter to <code>addInstances</code> RPC.</li>
 <li>Removed deprecated executor argument <code>-announcer-enable</code>, which was a no-op in 0.12.0.</li>
 <li>Removed deprecated API constructs related to Locks:

 <ul>
 <li>removed RPCs that managed locks

 <ul>
 <li><code>acquireLock</code></li>
 <li><code>releaseLock</code></li>
 <li><code>getLocks</code></li>
 </ul></li>
 <li>removed <code>Lock</code> parameters to RPCs

 <ul>
 <li><code>createJob</code></li>
 <li><code>scheduleCronJob</code></li>
 <li><code>descheduleCronJob</code></li>
 <li><code>restartShards</code></li>
 <li><code>killTasks</code></li>
 <li><code>addInstances</code></li>
 <li><code>replaceCronTemplate</code></li>
 </ul></li>
 </ul></li>
 <li>Task ID strings are no longer prefixed by a timestamp.</li>
 <li>Changes to the way the scheduler reads command line arguments

 <ul>
 <li>Removed support for reading command line argument values from files.</li>
 <li>Removed support for specifying command line argument names with fully-qualified class names.</li>
 </ul></li>
 </ul>
