   468  
   469  SECURITY:

   471   * driver/exec: Fix privilege escalation issue introduced in Nomad 0.9.0.  In
   472     Nomad 0.9.0 and 0.9.1, exec tasks by default run as `nobody` but with
   473     elevated capabilities, allowing tasks to perform privileged linux operations
   474     and potentially escalate permissions. (CVE-2019-12618)

   480     to be used internally only. [[GH-5275](https://github.com/hashicorp/nomad/pull/5275)]
   481   * api: The [job deployments](https://www.nomadproject.io/api/jobs.html#list-job-deployments) endpoint
   482     now filters out deployments associated with older instances of the job. This can happen if jobs are
   483     purged and recreated with the same id. To get all deployments irrespective of creation time, add

   557  
   558  ## 0.9.0 (April 9, 2019)
   559  
   560  __BACKWARDS INCOMPATIBILITIES:__
   561  
   562   * core: Drop support for CentOS/RHEL 6. glibc >= 2.14 is required.
   563   * core: Switch to structured logging using
   564     [go-hclog](https://github.com/hashicorp/go-hclog). If you have tooling that
   565     parses Nomad's logs, the format of logs has changed and your tools may need
   566     updating.
   567   * core: IOPS as a resource is now deprecated
   568     [[GH-4970](https://github.com/hashicorp/nomad/issues/4970)]. Nomad continues
   569     to parse IOPS in jobs to allow job authors time to remove iops from their
   570     jobs.
   571   * core: Allow the != constraint to match against keys that do not exist [[GH-4875](https://github.com/hashicorp/nomad/pull/4875)]
   572   * client: Task config validation is more strict in 0.9. For example unknown
   573     parameters in stanzas under the task config were ignored in previous
   574     versions but in 0.9 this will cause a task failure.
   575   * client: Task config interpolation requires names to be valid identifiers
   576     (`node.region` or `NOMAD_DC`). Interpolating other variables requires a new
   577     indexing syntax: `env[".invalid.identifier."]`. [[GH-4843](https://github.com/hashicorp/nomad/issues/4843)]
   578   * client: Node metadata variables must have valid identifiers, whether
   579     specified in the config file (`client.meta` stanza) or on the command line
   580     (`-meta`). [[GH-5158](https://github.com/hashicorp/nomad/pull/5158)]
   581   * driver/lxc: The LXC driver is no longer packaged with Nomad and is instead
   582     distributed separately as a driver plugin. Further, the LXC driver codebase
   583     is now in a separate
   584     [repository](https://github.com/hashicorp/nomad-driver-lxc). If you are using
   585     LXC, please follow the 0.9.0 upgrade guide as you will have to install the
   586     LXC driver before conducting an in-place upgrade to Nomad 0.9.0 [[GH-5162](https://github.com/hashicorp/nomad/issues/5162)]
   587  
   588  FEATURES:
   589  
   590   * **Affinities and Spread**: Jobs may now specify affinities towards certain
   591     node attributes. Affinities act as soft constraints, and inform the
   592     scheduler that the job has a preference for certain node properties. The new
   593     spread stanza informs the scheduler that allocations should be spread across a
   594     specific property such as datacenter or availability zone. This is useful to
   595     increase failure tolerance of critical applications.
   596   * **System Job Preemption**: System jobs may now preempt lower priority
   597     allocations. The ability to place system jobs on all targeted nodes is
   598     critical since system jobs often run applications that provide services for
   599     all allocations on the node.
   600   * **Driver Plugins**: Nomad now supports task drivers as plugins. Driver
   601     plugins operate the same as built-in drivers and can be developed and
   602     distributed independently from Nomad.
   603   * **Device Plugins**: Nomad now supports scheduling and mounting devices via
   604     device plugins. Device plugins expose hardware devices such as GPUs to Nomad
   605     and instruct the client on how to make them available to tasks. Device
   606     plugins can expose the health of devices, the devices attributes, and device
   607     usage statistics. Device plugins can be developed and distributed
   608     independently from Nomad.
   609   * **Nvidia GPU Device Plugin**: Nomad builds-in a Nvidia GPU device plugin to
   610     add out-of-the-box support for scheduling Nvidia GPUs.
   611   * **Client Refactor**: Major focus has been put in this release to refactor the
   612     Nomad Client codebase. The goal of the refactor has been to make the
   613     codebase more modular to increase developer velocity and testability.
   614   * **Mobile UI Views:** The side-bar navigation, breadcrumbs, and various other page
   615     elements are now responsively resized and repositioned based on your browser size.
   616   * **Job Authoring from the UI:** It is now possible to plan and submit new jobs, edit
   617     existing jobs, stop and start jobs, and promote canaries all from the UI.
   618   * **Improved Stat Tracking in UI:** The client detail, allocation detail, and task
   619     detail pages now have line charts that plot CPU and Memory usage changes over time.
   620   * **Structured Logging**: Nomad now uses structured logging with the ability to
   621     output logs in a JSON format.
   622  
   623  IMPROVEMENTS:

   850     allocation that was on a node that no longer exists
   851     [[GH-4215](https://github.com/hashicorp/nomad/issues/4215)]

   861  
   862  BUG FIXES:
   863   * client: Fix a race condition while concurrently fingerprinting and accessing
   864     the node that could cause a panic [[GH-4166](https://github.com/hashicorp/nomad/issues/4166)]
   865  
   866  ## 0.8.0 (April 12, 2018)
   867  
   868  __BACKWARDS INCOMPATIBILITIES:__
   869   * cli: node drain now blocks until the drain completes and all allocations on
   870     the draining node have stopped. Use -detach for the old behavior.
   871   * client: Periods (`.`) are no longer replaced with underscores (`_`) in
   872     environment variables as many applications rely on periods in environment
   873     variable names. [[GH-3760](https://github.com/hashicorp/nomad/issues/3760)]
   874   * client/metrics: The key emitted for tracking a client's uptime has changed
   875     from "uptime" to "client.uptime". Users monitoring this metric will have to
   876     switch to the new key name [[GH-4128](https://github.com/hashicorp/nomad/issues/4128)]
   877   * discovery: Prevent absolute URLs in check paths. The documentation indicated
   878     that absolute URLs are not allowed, but it was not enforced. Absolute URLs
   879     in HTTP check paths will now fail to validate. [[GH-3685](https://github.com/hashicorp/nomad/issues/3685)]
   880   * drain: Draining a node no longer stops all allocations immediately: a new
   881     [migrate stanza](https://www.nomadproject.io/docs/job-specification/migrate.html)
   882     allows jobs to specify how quickly task groups can be drained. A `-force`
   883     option can be used to emulate the old drain behavior.
   884   * jobspec: The default values for restart policy have changed. Restart policy
   885     mode defaults to "fail" and the attempts/time interval values have been
   886     changed to enable faster server side rescheduling. See [restart
   887     stanza](https://www.nomadproject.io/docs/job-specification/restart.html) for
   888     more information.
   889   * jobspec: Removed compatibility code that migrated pre Nomad 0.6.0 Update
   890     stanza syntax. All job spec files should be using update stanza fields
   891     introduced in 0.7.0

   908     the migrate stanza [[GH-4010](https://github.com/hashicorp/nomad/issues/4010)]
   909   * acl: Increase token name limit from 64 characters to 256 [[GH-3888](https://github.com/hashicorp/nomad/issues/3888)]

   976  
   977  __BACKWARDS INCOMPATIBILITIES:__
   978   * client: The format of service IDs in Consul has changed. If you rely upon
   979     Nomad's service IDs (*not* service names; those are stable), you will need
   980     to update your code.  [[GH-3632](https://github.com/hashicorp/nomad/issues/3632)]
   981   * config: Nomad no longer parses Atlas configuration stanzas. Atlas has been
   982     deprecated since earlier this year. If you have an Atlas stanza in your
   983     config file it will have to be removed.
   984   * config: Default minimum CPU configuration has been changed to 100 from 20. Jobs
   985     using the old minimum value of 20 will have to be updated.
   986   * telemetry: Hostname is now emitted via a tag rather than within the key name.
