### Commits

## 2017-04-14, Version 0.5.0, @drenter

### Notable changes

- Add DataDog support (mostly copied from the update-for-docker branch)
- Add support for `DATADOG_APIKEY` and `DATADOG_APPKEY` for above
- Add support for new `METRICS_ENABLED` environment variable, to explicitly control enabling and disabling metrics
- Add support for new `METRICS_INTERVAL` and `METRICS_FLUSH_FREQ` enviroment variables, either can be used to control the flush interval.
- Fixed a memory leak
- Update dependencies
- NOTE: The required parameters for configuration have slightly changed.  Where before only an `app` property was required, now both `appName` and `appType` should be used, where `appType` is something like `"api"` or `"fe"`.  Note that a corresponding `APPTYPE` environment variable is also supported.
