## 0.23.0

*Features*
- New command: `kubernetes-render` is a tool for rendering ERB templates to raw Kubernetes YAML. It's useful for seeing what `kubernetes-deploy` does before actually invoking `kubectl` on the rendered YAML. It's also useful for outputting YAML that can be passed to other tools, for validation or introspection purposes. ([#375](https://github.com/Shopify/kubernetes-deploy/pull/375/files))
- **[Breaking change]** This release completes the conversion of `kubernetes-deploy` StatsD metrics to `distribution`s, which was done for `kubernetes-restart` and `kubernetes-run` in v0.22.0.
- Several new distribution metrics are available to give insight into the timing of each step of the deploy process: `KubernetesDeploy.validate_configuration.duration`, `KubernetesDeploy.discover_resources.duration`, `KubernetesDeploy.validate_resources.duration`, `KubernetesDeploy.initial_status.duration`, `KubernetesDeploy.create_ejson_secrets.duration`, `KubernetesDeploy.apply_all.duration`, `KubernetesDeploy.sync.duration`
- **[Breaking change]** `KubernetesDeploy.resource.duration` no longer includes `sha` or `resource` tags. ([#392](https://github.com/Shopify/kubernetes-deploy/pull/392))

*Enhancements*
- Roles are now predeployed before RoleBindings ([#380](https://github.com/Shopify/kubernetes-deploy/pull/380))
- Several performance enhancements for deploys to namespaces with hundreds of resources.
- KubernetesDeploy no longer modifies the global StatsD configuration when used as a gem ([#384](https://github.com/Shopify/kubernetes-deploy/pull/384))

*Bug fixes*
- Handle out-of-order arrival of entries from different streams when processing logs ([#401](https://github.com/Shopify/kubernetes-deploy/pull/401))

## 0.22.0

*Features*
- **[Breaking change]** `kubernetes-restart` now produces StatsD `distribution` instead of `metric`.
Dashboards that used these metrics will need to be updated. ([#374](https://github.com/Shopify/kubernetes-deploy/pull/374))
- `kubernetes-run` now produces StatsD `distribution` to aid in tracking usage ([#374](https://github.com/Shopify/kubernetes-deploy/pull/374))

*Enhancements*
- Predeploy RoleBinding before unmanaged pods ([#354](https://github.com/Shopify/kubernetes-deploy/pull/354))

*Bug Fixes*
- Fixed bug in `kubernetes-restart` that caused "Pod spec does not contain a template
 container called 'task-runner'" error message to not be printed
 ([#371](https://github.com/Shopify/kubernetes-deploy/pull/371))

*Other*
- Kubernetes 1.8 is no longer officially supported as of this version

## 0.21.1

*Enhancements*
- Improved failure detection for job resources. ([#355](https://github.com/Shopify/kubernetes-deploy/pull/355))
- Unmanaged pods are now immediately identified as failed if they are evicted, preempted or deleted out of band. This is especially important to `kubernetes-run`. ([#353](https://github.com/Shopify/kubernetes-deploy/pull/353))

*Other*
- Relaxed our `googleauth` dependency. ([#333](https://github.com/Shopify/kubernetes-deploy/pull/333))

## 0.21.0

*Features*
- **[Breaking change]** `kubernetes-run` now streams container logs and waits for the pod to succeed or fail **by default**. You can disable this using `--skip-wait`, or you can use `--max-watch-seconds=seconds` to set a time limit on the watch. ([#337](https://github.com/Shopify/kubernetes-deploy/pull/337))


*Other*
- Kubernetes 1.7 is no longer officially supported as of this version

## 0.20.6

*Enhancements*
- All resources marked as prunable will now be added to the prune whitelist ([#326](https://github.com/Shopify/kubernetes-deploy/pull/326))
- Improve deploy status detection by ensuring we examine the correct generation ([#325](https://github.com/Shopify/kubernetes-deploy/pull/325))


## 0.20.5
*Enhancements*
- Add Job resource class ([#295](https://github.com/Shopify/kubernetes-deploy/pull/296))
- Add CustomResourceDefinition resource class ([#306](https://github.com/Shopify/kubernetes-deploy/pull/306))
- Officially support Kubernetes 1.10 ([#308](https://github.com/Shopify/kubernetes-deploy/pull/308))
- SyncMediator will only batch fetch resources when there is a sufficiently large enough set of resources
being tracked ([#316](https://github.com/Shopify/kubernetes-deploy/pull/316))
- Allow CRs to be pruned based on `kubernetes-deploy.shopify.io/prunable` annotation on the custom resource definitions ([312](https://github.com/Shopify/kubernetes-deploy/pull/312))
- Add HorizontalPodAutoscaler resource class ([#305](https://github.com/Shopify/kubernetes-deploy/pull/305))

*Bug Fixes*
- Prevent crash when STATSD_IMPLEMENTATION isn't set. ([#3242](https://github.com/Shopify/kubernetes-deploy/pull/324))

*Enhancements*
- Don't consider pod preempting a failure ([#317](https://github.com/shopify/kubernetes-deploy/pull/317))

### 0.20.3
*Enhancements*
- Evictions are recoverable so prevent them from triggering fast failure detection ([#293](https://github.com/Shopify/kubernetes-deploy/pull/293)).
- Use YAML.safe_load over YAML.load_file ([#295](https://github.com/Shopify/kubernetes-deploy/pull/295)).

### 0.20.0

*Features*
- Automatically add all Kubernetes namespace labels to StatsD tags ([#278](https://github.com/Shopify/kubernetes-deploy/pull/278))

*Bug Fixes*
- Prevent calling sleep with a negative value ([#273](https://github.com/Shopify/kubernetes-deploy/pull/273))
- Prevent no-op redeploys of bad code from hanging forever ([#262](https://github.com/Shopify/kubernetes-deploy/pull/262))

### 0.18.1
*Enhancements*
- Change the way the resource watcher fetches resources to make it more efficient for large deploys. Deploys with hundreds of resources are expected to see a measurable performance improvement from this change. ([#251](https://github.com/Shopify/kubernetes-deploy/pull/251))

### 0.18.0
*Features*
- kubernetes-restart and kubernetes-deploy use exit code 70 when a
deploy fails due to one or more resources failing to deploy in time.
([#244](https://github.com/Shopify/kubernetes-deploy/pull/244))

*Bug Fixes*
- Handle deploying thousands of resources at a time, previously kubernetes-deploy would fail with
 `Argument list too long - kubectl (Errno::E2BIG)`. ([#257](https://github.com/Shopify/kubernetes-deploy/pull/257))

### 0.17.0
*Enhancements*

- Add the `--cascade` flag when we force replace a resource. ([#250](https://github.com/Shopify/kubernetes-deploy/pull/250))

### 0.16.0
**Important:** This release changes the officially supported Kubernetes versions to v1.7 through v1.9. Other versions may continue to work, but we are no longer running our test suite against them.

*Features*
- Support partials to reduce duplication in yaml files ([#207](https://github.com/Shopify/kubernetes-deploy/pull/207))

*Bug Fixes*
- Handle podless deamon sets properly ([#242](https://github.com/Shopify/kubernetes-deploy/pull/242))

### 0.15.2
*Enhancements*
- Print warnings if kubernetes server version is not supported ([#237](https://github.com/Shopify/kubernetes-deploy/pull/237)).
- Possible via env var to disable fetching logs and/or events on deployment failure ([#239](https://github.com/Shopify/kubernetes-deploy/pull/239)).
- The `kubernetes-deploy.shopify.io/required-rollout` annotation now takes a percent (e.g. 90%) ([#240](https://github.com/Shopify/kubernetes-deploy/pull/240)).

### 0.15.1
*Enhancements*
- Fetch debug events and logs for failed resources in parallel ([#238](https://github.com/Shopify/kubernetes-deploy/pull/238))

### 0.15.0
*Bug Fixes*
- None

*Enhancements*
- Support for cronjob resource ([#206](https://github.com/Shopify/kubernetes-deploy/pull/206])).
- Make it possible to override the tool's hard timeout for one specific resource via the `kubernetes-deploy.shopify.io/timeout-override`
annotation ([#232](https://github.com/Shopify/kubernetes-deploy/pull/232)).
- Make it possible to modify how many replicas need to be updated and available before a deployment is considered
successful via the `kubernetes-deploy.shopify.io/required-rollout` annotation ([#208](https://github.com/Shopify/kubernetes-deploy/pull/208)).

### 0.14.1
*Bug Fixes*
- Make deployments whose pods crash because of CreateContainerConfigError fail fast in 1.8+ too (they would previously time out).
- Fix crashes when deploying ExternalName services or services without selectors ([#211](https://github.com/Shopify/kubernetes-deploy/pull/211))
- Predeploy ServiceAccount resources ([#221](https://github.com/Shopify/kubernetes-deploy/pull/221))

*Enhancements*
- Make it possible to pass bindings (via the --bindings flag) for which the value contains commas or is a JSON encoded hash ([#219](https://github.com/Shopify/kubernetes-deploy/pull/219))
- Support KUBECONFIG referencing multiple files ([#222](https://github.com/Shopify/kubernetes-deploy/pull/222))

### 0.14.0
*Bug Fixes*
- Fix incorrect timeouts occasionally observed on deployments using progressDeadlineSeconds in Kubernetes <1.7.7

*Enhancements*
- Renamed `KubernetesDeploy::Runner` (which powers `exe/kubernetes-deploy`) to `KubernetesDeploy::DeployTask`. This increases consistency between our primary class names and avoids confusion with `KubernetesDeploy::RunnerTask` (which powers `exe/kubernetes-run`).
- Improved output related to timeouts. For deployments, both failure and timeout output now mentions the referenced replica set.
- Small improvements to the reliability of the success polling.
- EjsonSecretProvisioner no longer logs kubectl command output (which may contain secret data) when debug-level logging is enabled.

### 0.13.0
*Features*

### 0.12.12
*Bug Fixes*
- Fix an issue deploying Shopify's internal custom resources.

### 0.12.11
*Bug Fixes*

### 0.12.10
*Enhancement*
- Log reason if deploy times out due to `progressDeadlineSeconds` being exceeded

### 0.12.9
*Bug Fixes*
- Retry discovering namespace and kubernetes context
- Expose real error during namespace discovery

### 0.12.8
*Bug Fixes*
- Force deployment to use its own hard timeout instead of relying on the replica set
