* [MESOS-1730] - Should be an error if commandinfo shell=true when using docker containerizer
* [MESOS-1732] - Mesos containerizer doesn't reject tasks with container info set
* [MESOS-1737] - Isolation=external result in core dump on 0.20.0

Release Notes - Mesos - Version 0.20.0
--------------------------------------
This release includes a lot of new cool features. The major new features are
listed below:
* Docker support in Mesos:
* Users now can launch executors/tasks within Docker containers.
* Mesos now supports running multiple containerizers simultaneously. The slave
can dynamically choose a containerizer to launch containers based on the
configuration of executors/tasks.
* Container level network monitoring for mesos containerizer:
* Network statistics for each active container can be retrieved through the
/monitor/statistics.json endpoint on the slave.
* Completely transparent to the tasks running on the slave. No need to change
the service discovery mechanism for tasks.
* Framework authorization:
* Allows frameworks to (re-)register with authorized roles.
* Allows frameworks to launch tasks/executors as authorized users.
* Allows authorized principals to shutdown framework(s) through HTTP endpoint.
* Framework rate limiting:
* In a multi-framework environment, this feature aims to protect the
throughput of high-SLA (e.g., production, service) frameworks by having the
master throttle messages from other (e.g., development, batch) frameworks.
* Enable building against installed third-party dependencies.
* API Changes:
* [MESOS-857] - The Python API now uses different namespacing. This will break
existing schedulers, please refer to the upgrades document.
* [MESOS-1409] - Status update acknowledgements are sent through the Master
now. This only affects you if you're using a non-Mesos binding (e.g. pure
language binding), in which case refer to the upgrades document.
* HTTP endpoint changes:
* [MESOS-1188] - "deactivated_slaves" represents inactive slaves in "/stats.json" and "/state.json".
* [MESOS-1390] - "/shutdown" authenticated endpoint has been added to master to shutdown a framework.
* Deprecations:
* [MESOS-1219] - Master should disallow completed frameworks from re-registering with same framework id.
* [MESOS-1695] - "/stats.json" on the slave exposes "registered" value as string instead of integer.
This release also includes several bug fixes and stability improvements.
** Sub-task
* [MESOS-1292] - [MESOS-1259]:Enrich the Java Docs in the src/java files. -- ZooKeeperState.java
* [MESOS-1293] - [MESOS-1259]:Enrich the Java Docs in the src/java files. -- Variable.java
* [MESOS-1294] - [MESOS-1259]:Enrich the Java Docs in the src/java files. -- State.java
** Bug
* [MESOS-445] - Scheduler driver destructor waits forever
* [MESOS-473] - Freezer fails fatally when it is unable to write 'FROZEN' to freezer.state
* [MESOS-759] - The cgroups TaskKiller should skip freezing the cgroup if it is already empty.
* [MESOS-856] - TasksKiller may run forever because the cgroup cannot be frozen.
* [MESOS-878] - Slave should not register with the master when in TERMINATING.
* [MESOS-1001] - registrar doesn't build on Linux/Clang
* [MESOS-1119] - Allocator should make an allocation decision per slave instead of per framework/role.

Release Notes - Mesos - Version 0.19.1
--------------------------------------
* This is a bug fix release.
** Bug
* [MESOS-1448] - Mesos Fetcher doesn't support URLs that have 30X redirects.
* [MESOS-1534] - Scheduler process is not explicitly terminated in the destructor of MesosSchedulerDriver.

* [MESOS-1539] - No longer able to spin up Mesos master in local mode.

Release Notes - Mesos - Version 0.19.0
--------------------------------------
* The primary feature of this release is the "Registrar". This is the addition
of replicated state in the master to ensure the set of slaves in the cluster
remains consistent in the presence of master failovers.
* This feature is currently used in a write-only manner by default to allow
smooth upgrades. 0.20.0 by default will be write *and* read.
* Operators must now specify the 'work_dir' for the master, along with the
'quorum' size of the ensemble of masters.
* This means adding or removing masters must be done carefully! The best
practice is to only ever add or remove a single master at a time and to
allow a small amount of time for the replicated log to catch up on the new
master.
* Authentication support has been added for slaves.
* Metrics reporting has been overhauled and is now exposed on /metrics/snapshot.
* Support for external containerization strategies has been added to support
custom container needs as well as experimentation; this is an alpha release!
* There are also several bug fixes and stability improvements.

Release Notes - Mesos - Version 0.14.0
--------------------------------------
* The primary feature in this release is "Slave Recovery" which allows
restarted slaves (e.g., deploys, crashes) to reconnect with old live
executors/tasks. To enable slave recovery:
* First you need to enable checkpointing on slaves with "--checkpoint" flag.
* Frameworks can opt in to this feature by setting "FrameworkInfo.checkpoint"
when registering with the master.
* Once a Framework opts in, a restarted slave will recover all the framework's
tasks and executors. The tasks/executors stay alive through a slave
restart and reconnect with the restarted slave.
* Slave recovery also improves the reliability of delivering status updates.
* The release also includes a new feature called "Resource Reservations" which
allows reserving resources on a slave to particular roles (This is an
experimental feature).
* This release also includes a new Mesos plugin for Jenkins which allows Jenkins
to dynamically launch Jenkins slaves on a Mesos cluster (This is an
experimental feature).
* There are also several bug fixes and stability improvements.

Release Notes - Mesos - Version 0.12.0
--------------------------------------
* This release includes bug fixes and stability improvements.
* The primary feature in this release is executor resource consumption monitoring. Slaves now monitor resource consumption of running executors and expose it over JSON and through the webui.
* This release also includes a new and improved Hadoop framework. The new port doesn't require patching Hadoop (i.e., it's a self contained Hadoop contrib) and lets you use existing schedulers (e.g., the fair scheduler or capacity scheduler)! The tradeoff, however, is that it doesn't take as much advantage of the fine-grained nature of a Mesos task (i.e., there is no longer a 1-1 mapping between a Mesos task and a map/reduce task).
** Sub-task
* [MESOS-214] - Report resources being used by executors
* [MESOS-419] - Old slave directories should not be garbage collected based on file modification time

* [MESOS-307] - Web UI file download links are broken.
* [MESOS-317] - python mesos core bindings rejects framework messages with null bytes
* [MESOS-319] - Fix buggy read / write calls.
* [MESOS-325] - make clean is broken
* [MESOS-332] - Executor launcher fetches resources as slave user, instead of executor user.
* [MESOS-340] - Gperftools target always rebuilds.
* [MESOS-374] - HTTP GET requests to /statistics/snapshot.json crash the slave
* [MESOS-422] - Master leader election should be more robust to stale ephemeral nodes
* [MESOS-486] - TaskInfo should include a 'source' in order to enable getting resource monitoring statistics.

** New Feature
* [MESOS-99] - display slave resource usage information in the slave webui
** Task
