    12  ## 0.9.0 (April 9, 2019)
    13  
    14  __BACKWARDS INCOMPATIBILITIES:__
    15  
    16   * core: Drop support for CentOS/RHEL 6. glibc >= 2.14 is required.
    17   * core: Switch to structured logging using
    18     [go-hclog](https://github.com/hashicorp/go-hclog). If you have tooling that
    19     parses Nomad's logs, the format of logs has changed and your tools may need
    20     updating.
    21   * core: IOPS as a resource is now deprecated
    22     [[GH-4970](https://github.com/hashicorp/nomad/issues/4970)]. Nomad continues
    23     to parse IOPS in jobs to allow job authors time to remove iops from their
    24     jobs.
    25   * core: Allow the != constraint to match against keys that do not exist [[GH-4875](https://github.com/hashicorp/nomad/pull/4875)]
    26   * client: Task config validation is more strict in 0.9. For example unknown
    27     parameters in stanzas under the task config were ignored in previous
    28     versions but in 0.9 this will cause a task failure.
    29   * client: Task config interpolation requires names to be valid identifiers
    30     (`node.region` or `NOMAD_DC`). Interpolating other variables requires a new
    31     indexing syntax: `env[".invalid.identifier."]`. [[GH-4843](https://github.com/hashicorp/nomad/issues/4843)]
    32   * client: Node metadata variables must have valid identifiers, whether
    33     specified in the config file (`client.meta` stanza) or on the command line
    34     (`-meta`). [[GH-5158](https://github.com/hashicorp/nomad/pull/5158)]
    35   * driver/lxc: The LXC driver is no longer packaged with Nomad and is instead
    36     distributed separately as a driver plugin. Further, the LXC driver codebase
    37     is now in a separate
    38     [repository](https://github.com/hashicorp/nomad-driver-lxc). If you are using
    39     LXC, please follow the 0.9.0 upgrade guide as you will have to install the
    40     LXC driver before conducting an in-place upgrade to Nomad 0.9.0 [[GH-5162](https://github.com/hashicorp/nomad/issues/5162)]
    41  
    42  FEATURES:
    43  
    44   * **Affinities and Spread**: Jobs may now specify affinities towards certain
    45     node attributes. Affinities act as soft constraints, and inform the
    46     scheduler that the job has a preference for certain node properties. The new
    47     spread stanza informs the scheduler that allocations should be spread across a
    48     specific property such as datacenter or availability zone. This is useful to
    49     increase failure tolerance of critical applications.
    50   * **System Job Preemption**: System jobs may now preempt lower priority
    51     allocations. The ability to place system jobs on all targeted nodes is
    52     critical since system jobs often run applications that provide services for
    53     all allocations on the node.
    54   * **Driver Plugins**: Nomad now supports task drivers as plugins. Driver
    55     plugins operate the same as built-in drivers and can be developed and
    56     distributed independently from Nomad.
    57   * **Device Plugins**: Nomad now supports scheduling and mounting devices via
    58     device plugins. Device plugins expose hardware devices such as GPUs to Nomad
    59     and instruct the client on how to make them available to tasks. Device
    60     plugins can expose the health of devices, the devices attributes, and device
    61     usage statistics. Device plugins can be developed and distributed
    62     independently from Nomad.
    63   * **Nvidia GPU Device Plugin**: Nomad builds-in a Nvidia GPU device plugin to
    64     add out-of-the-box support for scheduling Nvidia GPUs.
    65   * **Client Refactor**: Major focus has been put in this release to refactor the
    66     Nomad Client codebase. The goal of the refactor has been to make the
    67     codebase more modular to increase developer velocity and testability.
    68   * **Mobile UI Views:** The side-bar navigation, breadcrumbs, and various other page
    69     elements are now responsively resized and repositioned based on your browser size. 
    70   * **Job Authoring from the UI:** It is now possible to plan and submit new jobs, edit
    71     existing jobs, stop and start jobs, and promote canaries all from the UI.
    72   * **Improved Stat Tracking in UI:** The client detail, allocation detail, and task 
    73     detail pages now have line charts that plot CPU and Memory usage changes over time.
    74   * **Structured Logging**: Nomad now uses structured logging with the ability to
    75     output logs in a JSON format.
    76

   322  __BACKWARDS INCOMPATIBILITIES:__
   323   * cli: node drain now blocks until the drain completes and all allocations on
   324     the draining node have stopped. Use -detach for the old behavior.
   325   * client: Periods (`.`) are no longer replaced with underscores (`_`) in
   326     environment variables as many applications rely on periods in environment
   327     variable names. [[GH-3760](https://github.com/hashicorp/nomad/issues/3760)]
   328   * client/metrics: The key emitted for tracking a client's uptime has changed

   336     allows jobs to specify how quickly task groups can be drained. A `-force`
   337     option can be used to emulate the old drain behavior.
   338   * jobspec: The default values for restart policy have changed. Restart policy
   339     mode defaults to "fail" and the attempts/time interval values have been
   340     changed to enable faster server side rescheduling. See [restart
   341     stanza](https://www.nomadproject.io/docs/job-specification/restart.html) for
   342     more information.
   343   * jobspec: Removed compatibility code that migrated pre Nomad 0.6.0 Update
