+ <h1>Apache Mesos 0.23.0 Released</h1>
+
+ <p>The latest Mesos release, 0.23.0, is now available for <a
href="http://mesos.apache.org/downloads";>download</a>. This release includes
the following features and improvements:</p>
+
+<h4>Per-container network isolation (<a
href="https://issues.apache.org/jira/browse/MESOS-1585";>MESOS-1585</a>)</h4>
+
+<p>Mesos 0.23 provides support for per-container network monitoring and
isolation. Network isolation prevents a single container from exhausting the
available network ports, consuming an unfair share of the network bandwidth or
significantly delaying packet transmission for others. Network statistics for
each active container are published through the /monitor/statistics.json
endpoint on the slave. Network isolation is transparent for the majority of
tasks running on a slave (those that bind to port 0 and let the kernel allocate
their port). This feature is only available on Linux and requires a
configure-time flag.
+Refer to the <a
href="http://mesos.apache.org/documentation/latest/network-monitoring/";>network
monitoring and isolation documentation</a> for more information.</p>
+
+<h4>SSL (<a
href="https://issues.apache.org/jira/browse/MESOS-910";>MESOS-910</a>)</h4>
+
+<p>Experimental support for SSL encryption of any libprocess communication via
libevent. Encrypting traffic between the Mesos master and its slaves and
frameworks is important for information security, as it prevents eavesdropping
and impersonation. This feature requires a configure-time flag and will have
some performance impact.
+Refer to the <a
href="http://mesos.apache.org/documentation/latest/mesos-ssl/";>Mesos SSL
documentation</a> for instructions on building and enabling SSL.</p>
+
+<h4>Oversubscription (<a
href="https://issues.apache.org/jira/browse/MESOS-354";>MESOS-354</a>)</h4>
+
+<p>Experimental support for launching tasks/executors on revocable resources.
These resources can be revoked by Mesos at any time, causing the tasks using
them to be throttled or preempted.</p>
+
+<p>High-priority user-facing services are typically provisioned on large
clusters for peak load and unexpected load spikes. Hence, for most of time, the
provisioned resources remain underutilized. Oversubscription takes advantage of
temporarily unused resources to execute best-effort tasks such as background
analytics, video/image processing, chip simulations, and other low priority
jobs.</p>
+
+<p>Oversubscription adds two new slave components: a Resource Estimator and a
Quality of Service (QoS) Controller, alongside extending the existing resource
allocator, resource monitor, and mesos slave.
+Refer to the <a
href="http://mesos.apache.org/documentation/latest/oversubscription/";>oversubscription
documentation</a> for more information.</p>
+
+<h4>Persistent volumes (<a
href="https://issues.apache.org/jira/browse/MESOS-1554";>MESOS-1554</a>)</h4>
+
+<p>Experimental support for frameworks creating Persistent Volumes from disk
resources. This enables stateful services such as HDFS and Cassandra to store
their data within Mesos rather than having to resort to network-mounted EBS
volumes or unmanaged disk resources that need to be placed in a well-known
location.
+Refer to the <a
href="http://mesos.apache.org/documentation/latest/persistent-volume/";>persistent
volume documentation</a> for more information.</p>
+
+<h4>Dynamic reservations (<a
href="https://issues.apache.org/jira/browse/MESOS-2018";>MESOS-2018</a>)</h4>
+
+<p>Experimental support for frameworks dynamically reserving resources on
specific slaves for their role. Rather than requiring an operator to specify a
fixed, precalculated set of “static” reservations on slave startup,
a framework can now reserve resources as they are being offered, without
requiring a slave restart.
+No breaking changes were introduced with dynamic reservation, which means the
existing static reservation mechanism continues to be fully supported.
+Refer to the <a
href="http://mesos.apache.org/documentation/latest/reservation/";>reservation
documentation</a> for more information.</p>
+
+<h4>Fetcher caching (<a
href="https://issues.apache.org/jira/browse/MESOS-336";>MESOS-336</a>)</h4>
+
+<p>Experimental support for fetcher caching of executor/task binaries. The
fetcher can be instructed to cache URI downloads in a dedicated directory for
reuse by subsequent downloads. If the URIâs âcacheâ field has the value
âtrueâ, then the fetcher cache is in effect. If a URI is encountered for
the first time (for a particular user), it is first downloaded into the cache,
then copied to the sandbox directory from there. If the same URI is encountered
again (for the same user), and a corresponding cache file is resident in the
cache or still en route into the cache, then downloading is omitted and the
fetcher proceeds directly to copying from the cache.
+Refer to the <a
href="http://mesos.apache.org/documentation/latest/fetcher/";>fetcher
documentation</a> for more information.</p>
+
+<h4>NOTE: Experimental status</h4>
+
+<p>SSL, Oversubscription, Persistent Volumes, Dynamic Reservations, and
Fetcher Caching are all released as “experimental” features,
meaning that they are feature complete, at least for some use case, but have
not yet been tested in production environments. We welcome your feedback.</p>
+
+<h3>Changelog</h3>
+
+<p>Hundreds of other bug fixes/improvements are included in Mesos 0.23.0.
+See the <a
href="https://git-wip-us.apache.org/repos/asf?p=mesos.git;a=blob_plain;f=CHANGELOG;hb=0.23.0";>CHANGELOG</a>
for a full list of resolved JIRA issues.</p>
+
+<h3>Upgrades</h3>
+
+<p>Rolling upgrades from a Mesos 0.22.x cluster to Mesos 0.23 are
straightforward, but there are a few caveats/deprecations.
+Please refer to the <a
href="http://mesos.apache.org/documentation/latest/upgrades/";>upgrade guide</a>
for detailed information on upgrading to Mesos 0.23.</p>
+
+<h3>Compiler version requirement</h3>
+
+<p>Please note that Mesos 0.23.0 now requires gcc 4.8+ or clang 3.5+, so that
we can take advantage of C++11 language features.</p>
+
+<h3>Try it out</h3>
+
+<p>We encourage you to try out this release and let us know what you think. If
you run into any issues, please let us know on the <a
href="https://mesos.apache.org/community";>user mailing list and IRC</a>.</p>
