 	<h1>0.12.0 Released</h1>

 	<p>The latest Apache Aurora release, 0.12.0, 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 0.25.0.</li>
 <li>Upgraded the scheduler ZooKeeper client from 3.3.4 to 3.4.6.</li>
 <li>Added support for configuring Mesos role by passing <code>-mesos_role</code> to Aurora scheduler at start time.
 This enables resource reservation for Aurora when running in a shared Mesos cluster.</li>
 <li>Aurora task metadata is now mapped to Mesos task labels. Labels are prefixed with
 <code>org.apache.aurora.metadata.</code> to prevent clashes with other, external label sources.</li>
 <li>Added new scheduler flag <code>-default_docker_parameters</code> to allow a cluster operator to specify a
 universal set of parameters that should be used for every container that does not have parameters
 explicitly configured at the job level.</li>
 <li>Added support for jobs to specify arbitrary ZooKeeper paths for service registration.  See
 <a href="https://github.com/apache/aurora/blob/master/docs/configuration-reference.md#announcer-objects">here</a>
 for details.</li>
 <li>Log destination is configurable for the thermos runner. See the configuration reference for details
 on how to configure destination per-process. Command line options may also be passed through the
 scheduler in order to configure the global default behavior.</li>
 <li>Env variables can be passed through to task processes by passing <code>--preserve_env</code>
 to thermos.</li>
 <li>Changed scheduler logging to use logback.
 Operators wishing to customize logging may do so with standard logback configuration as described
 <a href="http://logback.qos.ch/manual/configuration.html">here</a></li>
 <li>When using <code>--read-json</code>, <code>aurora</code> can now load multiple jobs from one json file,
 similar to the usual pystachio structure: <code>{&quot;jobs&quot;: [job1, job2, ...]}</code>. The
 older single-job json format is also still supported.</li>
 <li><code>aurora config list</code> command now supports <code>--read-json</code></li>
 <li>Added scheduler command line argument <code>-shiro_after_auth_filter</code>. Optionally specify a class
 implementing javax.servlet.Filter that will be included in the Filter chain following the Shiro
 auth filters.</li>
 <li>The <code>addInstances</code> thrift RPC does now increase job instance count (scale out) based on the
 task template pointed by instance <code>key</code>.</li>
 </ul>

 <p>Deprecations and removals:</p>

 <ul>
 <li>Deprecated <code>AddInstancesConfig</code> argument in <code>addInstances</code> thrift RPC.</li>
 <li>Deprecated <code>TaskQuery</code> argument in <code>killTasks</code> thrift RPC to disallow killing tasks across
 multiple roles. The new safer approach is using <code>JobKey</code> with <code>instances</code> instead.</li>
 <li>Removed the deprecated field &lsquo;ConfigGroup.instanceIds&rsquo; from the API.</li>
 <li>Removed the following deprecated <code>HealthCheckConfig</code> client-side configuration fields: <code>endpoint</code>,
 <code>expected_response</code>, <code>expected_response_code</code>.  These are now set exclusively in like-named fields
 of <code>HttpHealthChecker.</code></li>
 <li>Removed the deprecated &#39;JobUpdateSettings.maxWaitToInstanceRunningMs&rsquo; thrift api field (
 UpdateConfig.restart_threshold in client-side configuration). This aspect of job restarts is now
 controlled exclusively via the client with <code>aurora job restart --restart-threshold=[seconds]</code>.</li>
 <li>Deprecated executor flag <code>--announcer-enable</code>. Enabling the announcer previously required both flags
 <code>--announcer-enable</code> and <code>--announcer-ensemble</code>, but now only <code>--announcer-ensemble</code> must be set.
 <code>--announcer-enable</code> is a no-op flag now and will be removed in future version.</li>
 <li>Removed scheduler command line arguments:

 <ul>
 <li><code>-enable_cors_support</code>.  Enabling CORS is now implicit by setting the argument
 <code>-enable_cors_for</code>.</li>
 <li><code>-deduplicate_snapshots</code> and <code>-deflate_snapshots</code>.  These features are good to always enable.</li>
 <li><code>-enable_job_updates</code> and <code>-enable_job_creation</code></li>
 <li><code>-extra_modules</code></li>
 <li><code>-logtostderr</code>, <code>-alsologtostderr</code>, <code>-vlog</code>, <code>-vmodule</code>, and <code>-use_glog_formatter</code>. Removed
 in favor of the new logback configuration.</li>
 </ul></li>
 </ul>
