Subject [VOTE] Release Apache Mesos 1.2.0 (rc2)
Date Fri, 24 Feb 2017 09:14:32 GMT
Dear Mesos developers and users,

Please vote on releasing the following candidate as Apache Mesos 1.2.0.

1.2.0 includes the following:
  * [MESOS-5931] - **Experimental** Support auto backend in Mesos
    prefering overlayfs then aufs. Please note that the bind backend needs
to be
    specified explicitly through the agent flag
    since it requires the sandbox already existed.

  * [MESOS-6402] - **Experimental** Add rlimit support to Mesos
    The isolator adds support for setting POSIX resource limits (rlimits)
    containers launched using the Mesos containerizer. POSIX rlimits can be
    to control the resources a process can consume. See `docs/`
    for details.

  * [MESOS-6419] - **Experimental** Teardown unregistered frameworks. The
    now treats recovered frameworks very similarly to frameworks that are
    but currently disconnected. For example, recovered frameworks will be
    via the normal "frameworks" key when querying HTTP endpoints. This
means there
    is no longer a concept of "orphan tasks": if the master knows about a
task, the
    task will be running under a framework. Similarly, "teardown"
operations on
    recovered frameworks will now work correctly.

  * [MESOS-6460] - **Experimental** Container Attach and Exec. This feature
    new Agent APIs for attaching a remote client to the stdin, stdout, and
    of a running Mesos task, as well as an API for launching new processes
    the same container as a running Mesos task and attaching to its stdin,
    and stderr. At a high level, these APIs mimic functionality similar to
    attach and docker exec. The primary motivation for such functionality
is to
    enable users to debug their running Mesos tasks.

  * [MESOS-6758] - **Experimental** Support 'Basic' auth docker private
    on Mesos Containerizer. Until now, the mesos containerizer always
    Bearer auth, but we now also support basic auth for private registries.
    note that the AWS ECS uses Basic authorization but it does not work yet
due to
    the redirect issue MESOS-5172.
