Release Notes - Mesos - Version 0.24.0
--------------------------------------------
This release contains experimental v1 scheduler HTTP API. This allows framework schedulers
to send HTTP requests to master endpoint ('/api/v1/scheduler') without the need for a driver.
The release also includes these features:
* [MESOS-336] - Mesos slave should cache executors
* API Changes:
* [MESOS-2293] - Implement the scheduler endpoint on master
* [MESOS-3135] - Publish MasterInfo to ZK using JSON
* [MESOS-2830] - Add an endpoint to slaves to allow launching system administration tasks
* Binary API Changes (e.g., new flags)
* [MESOS-3154] - Enable Mesos Agent Node to use arbitrary script / module to figure out IP, HOSTNAME
* [MESOS-809] - External control of the ip that Mesos components publish to zookeeper
* Deprecations:
* [MESOS-2736] - MasterInfo `ip`, `port` and `hostname` are deprecated in
favor of using the `address` field (see `Address` protobuf)
* Work In Progress:
* Support for 'Image' field added to 'Volume' and 'ContainerInfo' protobufs is incomplete.
This release also includes several bug fixes and stability improvements.

discoverability of tasks for external service discovery systems. Refer to
the framework development guide for more information.

Release Notes - Mesos - Version 0.21.0
--------------------------------------
This release includes several new features.
* State reconciliation for frameworks:
* Allows frameworks to reconcile the states of the tasks.
* Support for Mesos modules
* Support for modules in master, slave and tests using the --modules
flag.
* Task status now includes source and reason:
* [MESOS-343] - Expose TASK_FAILED reason to Frameworks.
* [MESOS-1143] - Add a TASK_ERROR task status.

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.

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.
