## 0.9.0 (Unreleased)
__BACKWARDS INCOMPATIBILITIES:__
* core: Switch to structured logging using [go-hclog](https://github.com/hashicorp/go-hclog)
* core: IOPS as a resource is now deprecated [[GH-4970](https://github.com/hashicorp/nomad/issues/4970)]
* core: Allow the != constraint to match against keys that do not exist [[GH-4875](https://github.com/hashicorp/nomad/pull/4875)]

* client: Node metadata variables must have valid identifiers, whether
specified in the config file (`client.meta` stanza) or on the command line
(`-meta`). [[GH-5158](https://github.com/hashicorp/nomad/pull/5158)]
* driver/lxc: The LXC driver is no longer packaged with Nomad and is instead
distributed separately as a driver plugin. Further, the LXC driver codebase
is now in a separate
[repository](https://github.com/hashicorp/nomad-driver-lxc). If you are using
LXC, please follow the 0.9.0 upgrade guide as you will have to install the
LXC driver before conducting an in-place upgrade to Nomad 0.9.0 [[GH-5162](https://github.com/hashicorp/nomad/issues/5162)]
FEATURES:
* **Affinities and Spread**: Job's may now specify affinities towards certain
node attributes. Affinities act as soft constraints, and inform the scheduler
that a preference for certain node properties exists. The new spread stanza
informs the scheduler that allocations should be spread across a specific
property such as datacenter or availability zone. This is useful to increase
failure tolerance of critical applications.
* **System Job Preemption**: System jobs may now preempt lower priority
allocations. The ability to place system jobs on all targeted nodes is
critical since system jobs often run applications that provide services for
all allocations on the node.
* **Driver Plugins**: Nomad now supports task drivers as plugins. Driver
plugins operate the same as built-in drivers and can be developed and
distributed independently from Nomad.
* **Device Plugins**: Nomad now supports scheduling and mounting devices via
device plugins. Device plugins expose hardware devices such as GPUs to Nomad
and instruct the client on how to make them available to tasks. Device
plugins can expose the health of devices, the devices attributes, and device
usage statistics. Device plugins can be developed and distributed
independently from Nomad.
* **Nvidia GPU Device Plugin**: Nomad builds-in a Nvidia GPU device plugin to
add out of the box support for scheduling Nvidia GPUs.
* **Client Refactor**: Major focus has been put in this release to refactor the
Nomad Client codebase. The goal of the refactor has been to make the
codebase more modular to increase developer velocity and testability.
* **Mobile UI Views:** The side-bar navigation, breadcrumbs, and various other page
elements are now responsively resized and repositioned based on your browser size.
* **Job Authoring from the UI:** It is now possible to plan and submit new jobs, edit
existing jobs, stop and start jobs, and promote canaries all from the UI.
* **Improved Stat Tracking in UI:** The client detail, allocation detail, and task
detail pages now have line charts that plot CPU and Memory usage changes over time.
* **Structured Logging**: Nomad now uses structured logging with the ability to
output logs in a JSON format.
IMPROVEMENTS:
* core: Added advertise address to client node meta data [[GH-4390](https://github.com/hashicorp/nomad/issues/4390)]

according to different node attributes [[GH-4512](https://github.com/hashicorp/nomad/issues/4512)]

target percentages across failure domains such as datacenter or rack [[GH-4512](https://github.com/hashicorp/nomad/issues/4512)]
