Release Notes - Mesos - Version 0.29.0 (WIP)
--------------------------------------------
This release contains the following new features:
* [MESOS-4909] - Tasks can now specify a kill policy. They are best-effort,
because machine failures or forcible terminations may occur. Currently, the
only available kill policy is how long to wait between graceful and forcible
task kill. In the future, more policies may be available (e.g. hitting an
HTTP endpoint, running a command, etc). Note that it is the executor's
responsibility to enforce kill policies. For executor-less command-based
tasks, the kill is performed via sending a signal to the task process:
SIGTERM for the graceful kill and SIGKILL for the forcible kill. For docker
executor-less tasks the grace period is passed to 'docker stop --time'. This
feature supersedes the '--docker_stop_timeout', which is now deprecated.
* [MESOS-4949] - The executor shutdown grace period can now be configured in
`ExecutorInfo`, which overrides the agent flag. When shutting down an
executor the agent will wait in a best-effort manner for the grace period
specified here before forcibly destroying the container. The executor must
not assume that it will always be allotted the full grace period, as the
agent may decide to allot a shorter period and failures / forcible
terminations may occur. Together with kill policies this gives frameworks
flexibility around how to clean up tasks and executors.
* [MESOS-4090] - The `mesos.native` python module has been split into two,
`mesos.executor` and `mesos.scheduler`. This change also removes
un-necessary 3rd party dependencies from `mesos.executor` and
`mesos.scheduler`. `mesos.native` still exists, combining both modules for
backwards compatibility with existing code.
* [MESOS-4828] - **Experimental** support for a new `xfs/disk' isolator
has been added to isolate disk resources more efficiently. Please refer to
docs/mesos-containerizer.md for more details.
Deprecations:
* [MESOS-2281] - Deprecated the plain text format for credentials in favor of
the JSON format.
* [MESOS-4910] - Deprecate the --docker_stop_timeout agent flag.
* [MESOS-5001] - The 'allocator/event_queue_dispatches' metric is now
deprecated in favor 'of allocator/mesos/event_queue_dispatches'.
* [MESOS-5029] - Deprecated the ExecutorInfo.source field in favor of
ExecutorInfo.labels.
Additional API Changes:
* [MESOS-4580] - Returning `202` (Accepted) for /reserve and related endpoints.
* [MESOS-4735] - Add 'output_file' field to CommandInfo.URI in Scheduler API
and v1 Scheduler HTTP API.
* [MESOS-5014] - Changes Call and Event Type enums in scheduler.proto
from required to optional for the purpose of backwards compatibility.
* [MESOS-5015] - Changes Call and Event Type enums in executor.proto
from required to optional for the purpose of backwards compatibility.
* [MESOS-5029] - Added 'labels' to ExecutorInfo.
* [MESOS-5030] - Added non-terminal task metadata to the container resource
usage information.
3rd Party Upgrades:
* [MESOS-4805] - Upgraded vendored ry-http-parser-1c3624a to nodejs/http-parser 2.6.1.
* [MESOS-4678] - Upgraded vendored protobuf 2.5.0 to 2.6.1.
* [MESOS-4803] - Upgraded vendored libev 4.15 to 4.22.
* [MESOS-4612] - Upgraded vendored ZooKeeper 3.4.5 to 3.4.8.
Binary API Changes:
* [MESOS-5055] - Replace Master/Slave Terminology Phase I - Update strings in
the log message and standard output
* [MESOS-3782] - Replace Master/Slave Terminology Phase I - Duplicate/Rename binaries.
* [MESOS-5057] - Replace Master/Slave Terminology Phase I - Update strings in
error messages and other strings
Release Notes - Mesos - Version 0.28.1
--------------------------------------
* This is a bug fix release.
All Issues:
** Bug
* [MESOS-4662] - PortMapping network isolator should not assume BIND_MOUNT_ROOT is a realpath.
* [MESOS-4874] - overlayfs does not work with kernel 4.2.3
* [MESOS-4877] - Mesos containerizer can't handle top level docker image like "alpine" (must use "library/alpine")
* [MESOS-4878] - Task stuck in TASK_STAGING when docker fetcher failed to fetch the image
* [MESOS-4964] - curl based docker fetcher fails to decode chunked encoding
* [MESOS-4985] - Destroy a container while it's provisioning can lead to leaked provisioned directories.
* [MESOS-5009] - local docker puller fails to find private registry repositories
* [MESOS-5018] - FrameworkInfo Capability enum does not support upgrades.
* [MESOS-5021] - Memory leak in subprocess when 'environment' argument is provided.
* [MESOS-5023] - MesosContainerizerProvisionerTest.DestroyWhileProvisioning is flaky.
* [MESOS-5114] - Flags::parse does not handle empty string correctly.
Release Notes - Mesos - Version 0.28.0
--------------------------------------
This release contains the following new features:
* [MESOS-4343] - A new cgroups isolator for enabling the net_cls subsystem in
Linux. The cgroups/net_cls isolator allows operators to provide network
performance isolation and network segmentation for containers within a Mesos
cluster. To enable the cgroups/net_cls isolator, append `cgroups/net_cls` to
the `--isolation` flag when starting the slave. Please refer to
docs/mesos-containerizer.md for more details.
* [MESOS-4687] - The implementation of scalar resource values (e.g., "2.5
CPUs") has changed. Mesos now reliably supports resources with up to three
decimal digits of precision (e.g., "2.501 CPUs"); resources with more than
three decimal digits of precision will be rounded. Internally, resource math
is now done using a fixed-point format that supports three decimal digits of
precision, and then converted to/from floating point for input and output,
respectively. Frameworks that do their own resource math and manipulate
fractional resources may observe differences in roundoff error and numerical
precision.
* [MESOS-4479] - Reserved resources can now optionally include "labels".
Labels are a set of key-value pairs that can be used to associate metadata
with a reserved resource. For example, frameworks can use this feature to
distinguish between two reservations for the same role at the same agent
that are intended for different purposes.
* [MESOS-2840] - **Experimental** support for container images in Mesos
containerizer (a.k.a. Unified Containerizer). This allows frameworks to
launch Docker/Appc containers using Mesos containerizer without relying on
docker daemon (engine) or rkt. The isolation of the containers is done using
isolators. Please refer to docs/container-image.md for currently supported
features and limitations.
* [MESOS-4793] - **Experimental** support for v1 Executor HTTP API. This
allows executors to send HTTP requests to the /api/v1/executor agent
endpoint without the need for an executor driver. Please refer to
docs/executor-http-api.md for more details.
* [MESOS-4370] Added support for service discovery of Docker containers that
use Docker Remote API v1.21.
Additional API Changes:
* [MESOS-4066] - Agent should not return partial state when a request is made
to /state endpoint during recovery.
* [MESOS-4547] - Introduce TASK_KILLING state.
* [MESOS-4712] - Remove 'force' field from the Subscribe Call in v1
Scheduler API.
* [MESOS-4591] - Change the object of ReserveResources and CreateVolume ACLs
to `roles`.
* [MESOS-3583] - Add stream IDs for HTTP schedulers.
* [MESOS-4427] - Ensure ip_address in state.json (from NetworkInfo) is valid.
All Issues:
** Bug
* [MESOS-1187] - precision errors with allocation calculations
* [MESOS-1469] - No output from review bot on timeout

Release Notes - Mesos - Version 0.24.1
--------------------------------------
* This is a bug fix release.
All Issues:
** Bug
* [MESOS-2986] - Docker version output is not compatible with Mesos
* [MESOS-3136] - COMMAND health checks with Marathon 0.10.0 are broken
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.
Additional API Changes:
* [MESOS-2293] - Implement the scheduler endpoint on master.
* [MESOS-3135] - Publish MasterInfo to ZK using JSON.
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.
