   209  __BACKWARDS INCOMPATIBILITIES:__
   210  
   211   * api: The `api` package removed `Config.SetTimeout` and `Config.ConfigureTLS` functions, intended
   212     to be used internally only. [[GH-5275](https://github.com/hashicorp/nomad/pull/5275)]
   213   * api: The [job deployments](https://www.nomadproject.io/api/jobs.html#list-job-deployments) endpoint
   214     now filters out deployments associated with older instances of the job. This can happen if jobs are
   215     purged and recreated with the same id. To get all deployments irrespective of creation time, add
   216     `all=true`. The `nomad job deployment`CLI also defaults to doing this filtering. [[GH-5702](https://github.com/hashicorp/nomad/issues/5702)]
   217   * client: The format of service IDs in Consul has changed. If you rely upon

   222   * client: On startup a client will reattach to running tasks as before but
   223     will not restart exited tasks. Exited tasks will be restarted only after the
   224     client has reestablished communication with servers. System jobs will always
   225     be restarted. [[GH-5669](https://github.com/hashicorp/nomad/pull/5669)]

   289  
   290  ## 0.9.0 (April 9, 2019)
   291  
   292  __BACKWARDS INCOMPATIBILITIES:__
   293  
   294   * core: Drop support for CentOS/RHEL 6. glibc >= 2.14 is required.
   295   * core: Switch to structured logging using
   296     [go-hclog](https://github.com/hashicorp/go-hclog). If you have tooling that
   297     parses Nomad's logs, the format of logs has changed and your tools may need
   298     updating.
   299   * core: IOPS as a resource is now deprecated
   300     [[GH-4970](https://github.com/hashicorp/nomad/issues/4970)]. Nomad continues
   301     to parse IOPS in jobs to allow job authors time to remove iops from their
   302     jobs.
   303   * core: Allow the != constraint to match against keys that do not exist [[GH-4875](https://github.com/hashicorp/nomad/pull/4875)]
   304   * client: Task config validation is more strict in 0.9. For example unknown
   305     parameters in stanzas under the task config were ignored in previous
   306     versions but in 0.9 this will cause a task failure.
   307   * client: Task config interpolation requires names to be valid identifiers
   308     (`node.region` or `NOMAD_DC`). Interpolating other variables requires a new
   309     indexing syntax: `env[".invalid.identifier."]`. [[GH-4843](https://github.com/hashicorp/nomad/issues/4843)]
   310   * client: Node metadata variables must have valid identifiers, whether
   311     specified in the config file (`client.meta` stanza) or on the command line
   312     (`-meta`). [[GH-5158](https://github.com/hashicorp/nomad/pull/5158)]
   313   * driver/lxc: The LXC driver is no longer packaged with Nomad and is instead
   314     distributed separately as a driver plugin. Further, the LXC driver codebase
   315     is now in a separate
   316     [repository](https://github.com/hashicorp/nomad-driver-lxc). If you are using
   317     LXC, please follow the 0.9.0 upgrade guide as you will have to install the
   318     LXC driver before conducting an in-place upgrade to Nomad 0.9.0 [[GH-5162](https://github.com/hashicorp/nomad/issues/5162)]
   319  
   320  FEATURES:
   321  
   322   * **Affinities and Spread**: Jobs may now specify affinities towards certain
   323     node attributes. Affinities act as soft constraints, and inform the
   324     scheduler that the job has a preference for certain node properties. The new
   325     spread stanza informs the scheduler that allocations should be spread across a
   326     specific property such as datacenter or availability zone. This is useful to
   327     increase failure tolerance of critical applications.
   328   * **System Job Preemption**: System jobs may now preempt lower priority
   329     allocations. The ability to place system jobs on all targeted nodes is
   330     critical since system jobs often run applications that provide services for
   331     all allocations on the node.
   332   * **Driver Plugins**: Nomad now supports task drivers as plugins. Driver
   333     plugins operate the same as built-in drivers and can be developed and
   334     distributed independently from Nomad.
   335   * **Device Plugins**: Nomad now supports scheduling and mounting devices via
   336     device plugins. Device plugins expose hardware devices such as GPUs to Nomad
   337     and instruct the client on how to make them available to tasks. Device
   338     plugins can expose the health of devices, the devices attributes, and device
   339     usage statistics. Device plugins can be developed and distributed
   340     independently from Nomad.
   341   * **Nvidia GPU Device Plugin**: Nomad builds-in a Nvidia GPU device plugin to
   342     add out-of-the-box support for scheduling Nvidia GPUs.
   343   * **Client Refactor**: Major focus has been put in this release to refactor the
   344     Nomad Client codebase. The goal of the refactor has been to make the
   345     codebase more modular to increase developer velocity and testability.
   346   * **Mobile UI Views:** The side-bar navigation, breadcrumbs, and various other page
   347     elements are now responsively resized and repositioned based on your browser size.
   348   * **Job Authoring from the UI:** It is now possible to plan and submit new jobs, edit
   349     existing jobs, stop and start jobs, and promote canaries all from the UI.
   350   * **Improved Stat Tracking in UI:** The client detail, allocation detail, and task
   351     detail pages now have line charts that plot CPU and Memory usage changes over time.
   352   * **Structured Logging**: Nomad now uses structured logging with the ability to
   353     output logs in a JSON format.

   598  ## 0.8.0 (April 12, 2018)
   599  
   600  __BACKWARDS INCOMPATIBILITIES:__
   601   * cli: node drain now blocks until the drain completes and all allocations on
   602     the draining node have stopped. Use -detach for the old behavior.
   603   * client: Periods (`.`) are no longer replaced with underscores (`_`) in
   604     environment variables as many applications rely on periods in environment
   605     variable names. [[GH-3760](https://github.com/hashicorp/nomad/issues/3760)]
   606   * client/metrics: The key emitted for tracking a client's uptime has changed
   607     from "uptime" to "client.uptime". Users monitoring this metric will have to
   608     switch to the new key name [[GH-4128](https://github.com/hashicorp/nomad/issues/4128)]
   609   * discovery: Prevent absolute URLs in check paths. The documentation indicated
   610     that absolute URLs are not allowed, but it was not enforced. Absolute URLs
   611     in HTTP check paths will now fail to validate. [[GH-3685](https://github.com/hashicorp/nomad/issues/3685)]
   612   * drain: Draining a node no longer stops all allocations immediately: a new
   613     [migrate stanza](https://www.nomadproject.io/docs/job-specification/migrate.html)
   614     allows jobs to specify how quickly task groups can be drained. A `-force`
   615     option can be used to emulate the old drain behavior.
   616   * jobspec: The default values for restart policy have changed. Restart policy
   617     mode defaults to "fail" and the attempts/time interval values have been
   618     changed to enable faster server side rescheduling. See [restart
   619     stanza](https://www.nomadproject.io/docs/job-specification/restart.html) for
   620     more information.
   621   * jobspec: Removed compatibility code that migrated pre Nomad 0.6.0 Update
   622     stanza syntax. All job spec files should be using update stanza fields
   623     introduced in 0.7.0

  1521  __BACKWARDS INCOMPATIBILITIES:__
  1522    * Stdout and Stderr log files of tasks have moved from task/local to
  1523      alloc/logs [[GH-851](https://github.com/hashicorp/nomad/issues/851)]
  1524    * Any users of the runtime environment variable `$NOMAD_PORT_` will need to
  1525      update to the new `${NOMAD_ADDR_}` variable [[GH-704](https://github.com/hashicorp/nomad/issues/704)]
  1526    * Service names that include periods will fail validation. To fix, remove any
  1527      periods from the service name before running the job [[GH-770](https://github.com/hashicorp/nomad/issues/770)]
  1528    * Task resources are now validated and enforce minimum resources. If a job
  1529      specifies resources below the minimum they will need to be updated [[GH-739](https://github.com/hashicorp/nomad/issues/739)]
  1530    * Node ID is no longer specifiable. For users who have set a custom Node
  1531      ID, the node should be drained before Nomad is updated and the data_dir

  1533    * Users of custom restart policies should update to the new syntax which adds
  1534      a `mode` field. The `mode` can be either `fail` or `delay`. The default for
  1535      `batch` and `service` jobs is `fail` and `delay` respectively [[GH-594](https://github.com/hashicorp/nomad/issues/594)]
  1536    * All jobs that interpret variables in constraints or driver configurations
  1537      will need to be updated to the new syntax which wraps the interpreted
  1538      variable in curly braces. (`$node.class` becomes `${node.class}`) [[GH-760](https://github.com/hashicorp/nomad/issues/760)]
