   174  ## 0.8.0 (April 12, 2018)
   175  
   176  __BACKWARDS INCOMPATIBILITIES:__
   177   * cli: node drain now blocks until the drain completes and all allocations on
   178     the draining node have stopped. Use -detach for the old behavior.
   179   * client: Periods (`.`) are no longer replaced with underscores (`_`) in
   180     environment variables as many applications rely on periods in environment
   181     variable names. [[GH-3760](https://github.com/hashicorp/nomad/issues/3760)]
   182   * client/metrics: The key emitted for tracking a client's uptime has changed
   183     from "uptime" to "client.uptime". Users monitoring this metric will have to
   184     switch to the new key name [[GH-4128](https://github.com/hashicorp/nomad/issues/4128)]
   185   * discovery: Prevent absolute URLs in check paths. The documentation indicated
   186     that absolute URLs are not allowed, but it was not enforced. Absolute URLs
   187     in HTTP check paths will now fail to validate. [[GH-3685](https://github.com/hashicorp/nomad/issues/3685)]
   188   * drain: Draining a node no longer stops all allocations immediately: a new
   189     [migrate stanza](https://www.nomadproject.io/docs/job-specification/migrate.html)
   190     allows jobs to specify how quickly task groups can be drained. A `-force`
   191     option can be used to emulate the old drain behavior.
   192   * jobspec: The default values for restart policy have changed. Restart policy
   193     mode defaults to "fail" and the attempts/time interval values have been
   194     changed to enable faster server side rescheduling. See [restart
   195     stanza](https://www.nomadproject.io/docs/job-specification/restart.html) for
   196     more information.
   197   * jobspec: Removed compatibility code that migrated pre Nomad 0.6.0 Update
   198     stanza syntax. All job spec files should be using update stanza fields
   199     introduced in 0.7.0
   200     [[GH-3979](https://github.com/hashicorp/nomad/pull/3979/files)]

   285  __BACKWARDS INCOMPATIBILITIES:__
   286   * client: The format of service IDs in Consul has changed. If you rely upon

   292   * config: Default minimum CPU configuration has been changed to 100 from 20. Jobs
   293     using the old minimum value of 20 will have to be updated.

  1105      specifies resources below the minimum they will need to be updated [[GH-739](https://github.com/hashicorp/nomad/issues/739)]
  1106    * Node ID is no longer specifiable. For users who have set a custom Node
  1107      ID, the node should be drained before Nomad is updated and the data_dir

  1109    * Users of custom restart policies should update to the new syntax which adds
  1110      a `mode` field. The `mode` can be either `fail` or `delay`. The default for
  1111      `batch` and `service` jobs is `fail` and `delay` respectively [[GH-594](https://github.com/hashicorp/nomad/issues/594)]
  1112    * All jobs that interpret variables in constraints or driver configurations
  1113      will need to be updated to the new syntax which wraps the interpreted
  1114      variable in curly braces. (`$node.class` becomes `${node.class}`) [[GH-760](https://github.com/hashicorp/nomad/issues/760)]
