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. 354 355 IMPROVEMENTS: 356 357 * core: Added advertise address to client node meta data [[GH-4390](https://github.com/hashicorp/nomad/issues/4390)] 358 * core: Added support for specifying node affinities. Affinities allow job operators to specify weighted placement preferences according to different node attributes [[GH-4512](https://github.com/hashicorp/nomad/issues/4512)] 359 * core: Added support for spreading allocations across a specific attribute. Operators can specify spread target percentages across failure domains such as datacenter or rack [[GH-4512](https://github.com/hashicorp/nomad/issues/4512)] 360 * core: Added preemption support for system jobs. System jobs can now preempt other jobs of lower priority. See [preemption](https://www.nomadproject.io/docs/internals/scheduling/preemption.html) for more details.
