## 0.3.2 (UNRELEASED)
IMPROVEMENTS:
* core: Allow count zero task groups to enable blue/green deploys [GH-931]
* core: Job Deregister forces an evaluation for the job even if it doesn't
exist [GH-981]
* core: Rename successfully finished allocations to "Complete" rather than
"Dead" for clarity [GH-975]
* cli: `alloc-status` explains restart decisions [GH-984]
* cli: Destructive commands now require confirmation [GH-983]
* cli: `alloc-status` display is less verbose by default [GH-946]
* cli: `server-members` displays the current leader in each region [GH-935]
* cli: New `inspect` command to display a submitted job's specification
[GH-952]
* cli: `node-status` display is less verbose by default and shows a node's
total resources [GH-946]
* client: Nomad fingerprinter to detect client's version [GH-965]
* client: Pass environment variables from host to exec based tasks [GH-970]
* client: Allow task's to be run as particular user [GH-950, GH-978]
* client: `artifact` block now supports downloading paths relative to the
task's directory [GH-944]
BUG FIXES:
* core: Fix issue where in-place updated allocation double counted resources
[GH-957]
* core: Prevent garbage collection of running batch jobs [GH-989]
* client: Tasks can interpret Meta set in the task group and job [GH-985]
## 0.3.1
__BACKWARDS INCOMPATIBILITIES:__
* Service names that dont conform to RFC-1123 and RFC-2782 will fail
validation. To fix, change service name to conform to the RFCs before
running the job [GH-915]
* Jobs that downloaded artifacts will have to be updated to the new syntax and
be resubmitted. The new syntax consolidates artifacts to the `task` rather
than being duplicated inside each driver config [GH-921]
IMPROVEMENTS:
* cli: Validate job file schemas [GH-900]
* client: Add environment variables for task name, allocation ID/Name/Index
[GH-869, GH-896]
* client: Starting task is retried under the restart policy if the error is
recoverable [GH-859]
* client: Allow tasks to download artifacts, which can be archives, prior to
starting [GH-921]
* config: Validate Nomad configuration files [GH-910]
* config: Client config allows reserving resources [GH-910]
* driver/docker: Support for ECR [GH-858]
* driver/docker: Periodic Fingerprinting [GH-893]
* driver/docker: Preventing port reservation for log collection on Unix platforms [GH-897]
* driver/rkt: Pass DNS information to rkt driver [GH-892]
* jobspec: Require RFC-1123 and RFC-2782 valid service names [GH-915]
BUG FIXES:
* core: No longer cancel evaluations that are delayed in the plan queue
[GH-884]
* api: Guard client/fs/ APIs from being accessed on a non-client node [GH-890]
* client: Allow dashes in variable names during interprelation [GH-857]
* client: Updating kill timeout adheres to operator specified maximum value [GH-878]
* client: Fix a case in which clients would pull but not run allocations
[GH-906]
* consul: Remove concurrent map access [GH-874]
* driver/exec: Stopping tasks with more than one pid in a cgroup [GH-855]
* executor/linux: Add /run/resolvconf/ to chroot so DNS works [GH-905]
## 0.3.0
__BACKWARDS INCOMPATIBILITIES:__
* Stdout and Stderr log files of tasks have moved from task/local to
alloc/logs [GH-851]
* Any users of the runtime environment variable `$NOMAD_PORT_` will need to
update to the new `${NOMAD_ADDR_}` varriable [GH-704]
* Service names that include periods will fail validation. To fix, remove any
periods from the service name before running the job [GH-770]
* Task resources are now validated and enforce minimum resources. If a job
specifies resources below the minimum they will need to be updated [GH-739]
* Node ID is no longer specifiable. For users who have set a custom Node
ID, the node should be drained before Nomad is updated and the data_dir
should be deleted before starting for the first time [GH-675]
* Users of custom restart policies should update to the new syntax which adds
a `mode` field. The `mode` can be either `fail` or `delay`. The default for
`batch` and `service` jobs is `fail` and `delay` respectively [GH-594]
* All jobs that interpret variables in constraints or driver configurations
will need to be updated to the new syntax which wraps the interpreted
variable in curly braces. (`$node.class` becomes `${node.class}`) [GH-760]
