   780  
   781  __BACKWARDS INCOMPATIBILITIES:__
   782  
   783   * client/template: When rendering a task template, only task environment variables are included by default. [[GH-6055](https://github.com/hashicorp/nomad/issues/6055)]
   784   * client/template: When rendering a task template, the `plugin` function is no longer permitted by default and will raise an error. [[GH-6075](https://github.com/hashicorp/nomad/issues/6075)]
   785   * client/template: When rendering a task template, path parameters for the `file` function will be restricted to the task directory by default. Relative paths or symlinks that point outside the task directory will raise an error. [[GH-6075](https://github.com/hashicorp/nomad/issues/6075)]
   786  
   787  IMPROVEMENTS:

   850  ## 0.9.2 (June 5, 2019)
   851  
   852  SECURITY:
   853  
   854   * driver/exec: Fix privilege escalation issue introduced in Nomad 0.9.0.  In
   855     Nomad 0.9.0 and 0.9.1, exec tasks by default run as `nobody` but with
   856     elevated capabilities, allowing tasks to perform privileged linux operations
   857     and potentially escalate permissions. (CVE-2019-12618)
   858     [[GH-5728](https://github.com/hashicorp/nomad/pull/5728)]
   859  
   860  __BACKWARDS INCOMPATIBILITIES:__
   861  
   862   * api: The `api` package removed `Config.SetTimeout` and `Config.ConfigureTLS` functions, intended
   863     to be used internally only. [[GH-5275](https://github.com/hashicorp/nomad/pull/5275)]
   864   * api: The [job deployments](https://www.nomadproject.io/api/jobs.html#list-job-deployments) endpoint
   865     now filters out deployments associated with older instances of the job. This can happen if jobs are
   866     purged and recreated with the same id. To get all deployments irrespective of creation time, add
   867     `all=true`. The `nomad job deployment`CLI also defaults to doing this filtering. [[GH-5702](https://github.com/hashicorp/nomad/issues/5702)]
   868   * client: The format of service IDs in Consul has changed. If you rely upon
   869     Nomad's service IDs (*not* service names; those are stable), you will need
   870     to update your code.  [[GH-5536](https://github.com/hashicorp/nomad/pull/5536)]
   871   * client: The format of check IDs in Consul has changed. If you rely upon
   872     Nomad's check IDs you will need to update your code.  [[GH-5536](https://github.com/hashicorp/nomad/pull/5536)]
   873   * client: On startup a client will reattach to running tasks as before but
   874     will not restart exited tasks. Exited tasks will be restarted only after the
   875     client has reestablished communication with servers. System jobs will always
   876     be restarted. [[GH-5669](https://github.com/hashicorp/nomad/pull/5669)]

   940  
   941  ## 0.9.0 (April 9, 2019)
   942  
   943  __BACKWARDS INCOMPATIBILITIES:__
   944  
   945   * core: Drop support for CentOS/RHEL 6. glibc >= 2.14 is required.
   946   * core: Switch to structured logging using
   947     [go-hclog](https://github.com/hashicorp/go-hclog). If you have tooling that
   948     parses Nomad's logs, the format of logs has changed and your tools may need
   949     updating.
   950   * core: IOPS as a resource is now deprecated
   951     [[GH-4970](https://github.com/hashicorp/nomad/issues/4970)]. Nomad continues
   952     to parse IOPS in jobs to allow job authors time to remove iops from their
   953     jobs.
   954   * core: Allow the != constraint to match against keys that do not exist [[GH-4875](https://github.com/hashicorp/nomad/pull/4875)]
   955   * client: Task config validation is more strict in 0.9. For example unknown
   956     parameters in stanzas under the task config were ignored in previous
   957     versions but in 0.9 this will cause a task failure.
   958   * client: Task config interpolation requires names to be valid identifiers
   959     (`node.region` or `NOMAD_DC`). Interpolating other variables requires a new
   960     indexing syntax: `env[".invalid.identifier."]`. [[GH-4843](https://github.com/hashicorp/nomad/issues/4843)]
   961   * client: Node metadata variables must have valid identifiers, whether
   962     specified in the config file (`client.meta` stanza) or on the command line
   963     (`-meta`). [[GH-5158](https://github.com/hashicorp/nomad/pull/5158)]
   964   * driver/lxc: The LXC driver is no longer packaged with Nomad and is instead
   965     distributed separately as a driver plugin. Further, the LXC driver codebase
   966     is now in a separate
   967     [repository](https://github.com/hashicorp/nomad-driver-lxc). If you are using
   968     LXC, please follow the 0.9.0 upgrade guide as you will have to install the
   969     LXC driver before conducting an in-place upgrade to Nomad 0.9.0 [[GH-5162](https://github.com/hashicorp/nomad/issues/5162)]
   970  
   971  FEATURES:
   972  
   973   * **Affinities and Spread**: Jobs may now specify affinities towards certain
   974     node attributes. Affinities act as soft constraints, and inform the
   975     scheduler that the job has a preference for certain node properties. The new
   976     spread stanza informs the scheduler that allocations should be spread across a
   977     specific property such as datacenter or availability zone. This is useful to
   978     increase failure tolerance of critical applications.
   979   * **System Job Preemption**: System jobs may now preempt lower priority
   980     allocations. The ability to place system jobs on all targeted nodes is
   981     critical since system jobs often run applications that provide services for
   982     all allocations on the node.
   983   * **Driver Plugins**: Nomad now supports task drivers as plugins. Driver
   984     plugins operate the same as built-in drivers and can be developed and
   985     distributed independently from Nomad.
   986   * **Device Plugins**: Nomad now supports scheduling and mounting devices via
   987     device plugins. Device plugins expose hardware devices such as GPUs to Nomad
   988     and instruct the client on how to make them available to tasks. Device
   989     plugins can expose the health of devices, the devices attributes, and device

  1248  
  1249  ## 0.8.0 (April 12, 2018)
  1250  
  1251  __BACKWARDS INCOMPATIBILITIES:__
  1252   * cli: node drain now blocks until the drain completes and all allocations on
  1253     the draining node have stopped. Use -detach for the old behavior.
  1254   * client: Periods (`.`) are no longer replaced with underscores (`_`) in
  1255     environment variables as many applications rely on periods in environment
  1256     variable names. [[GH-3760](https://github.com/hashicorp/nomad/issues/3760)]
  1257   * client/metrics: The key emitted for tracking a client's uptime has changed
  1258     from "uptime" to "client.uptime". Users monitoring this metric will have to
  1259     switch to the new key name [[GH-4128](https://github.com/hashicorp/nomad/issues/4128)]
  1260   * discovery: Prevent absolute URLs in check paths. The documentation indicated
  1261     that absolute URLs are not allowed, but it was not enforced. Absolute URLs
  1262     in HTTP check paths will now fail to validate. [[GH-3685](https://github.com/hashicorp/nomad/issues/3685)]
  1263   * drain: Draining a node no longer stops all allocations immediately: a new
  1264     [migrate stanza](https://www.nomadproject.io/docs/job-specification/migrate.html)
  1265     allows jobs to specify how quickly task groups can be drained. A `-force`
  1266     option can be used to emulate the old drain behavior.
  1267   * jobspec: The default values for restart policy have changed. Restart policy
  1268     mode defaults to "fail" and the attempts/time interval values have been
  1269     changed to enable faster server side rescheduling. See [restart
  1270     stanza](https://www.nomadproject.io/docs/job-specification/restart.html) for
  1271     more information.
  1272   * jobspec: Removed compatibility code that migrated pre Nomad 0.6.0 Update
  1273     stanza syntax. All job spec files should be using update stanza fields
  1274     introduced in 0.7.0

  1358  ## 0.7.1 (December 19, 2017)
  1359  
  1360  __BACKWARDS INCOMPATIBILITIES:__
  1361   * client: The format of service IDs in Consul has changed. If you rely upon
  1362     Nomad's service IDs (*not* service names; those are stable), you will need
  1363     to update your code.  [[GH-3632](https://github.com/hashicorp/nomad/issues/3632)]
  1364   * config: Nomad no longer parses Atlas configuration stanzas. Atlas has been
  1365     deprecated since earlier this year. If you have an Atlas stanza in your
  1366     config file it will have to be removed.
  1367   * config: Default minimum CPU configuration has been changed to 100 from 20. Jobs
  1368     using the old minimum value of 20 will have to be updated.
  1369   * telemetry: Hostname is now emitted via a tag rather than within the key name.
  1370     To maintain old behavior during an upgrade path specify
  1371     `backwards_compatible_metrics` in the telemetry configuration.
