Release Notes - Mesos - Version 0.23.0
--------------------------------------------
This release contains new features:
* [MESOS-1585] - Per-container network isolation: bandwidth capping and unique

* Volumes can be mounted from the host into a container's
filesystem.
* Parts of the shared filesystem can be made private to each
container, e.g., a private /tmp for each container.
* A pid namespace isolator:
* Processes inside a container will not have visibility to host
processes or processes in any other container.
* Containers will be destroyed by terminating the 'init' process for
the pid namespace rather than using the freezer cgroup, avoiding known
kernel bugs.
* API Changes:
* [MESOS-1461] - Add task reconciliation to the Python API.
* Deprecations:
* [MESOS-1807] - Disallow executors with cpu only or memory only resources.
* [MESOS-1986] - Disabling checkpointing is deprecated and the --checkpoint flag will be removed in a future release.
* Build changes:
* [MESOS-1044] - Require C++11 compiler support.
This release also includes several bug fixes and stability
improvements.

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.

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-1538] - A container destruction in the middle of a launch leads to CHECK failure.
* [MESOS-1539] - No longer able to spin up Mesos master in local mode.
* [MESOS-1550] - MesosSchedulerDriver should never, ever, call 'stop'.
* [MESOS-1551] - Master does not create work directory when missing.
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
