### Changed

- All the modules in [`pkg/sdk`](https://github.com/operator-framework/operator-sdk/tree/master/pkg/sdk) have been combined into a single package. `action`, `handler`, `informer` `types` and `query` pkgs have been consolidated into `pkg/sdk`. [#242](https://github.com/operator-framework/operator-sdk/pull/242)
- The SDK exposes the Kubernetes clientset via `k8sclient.GetKubeClient()` #295
