Dependency deprecation warning: travis-deploy-once (npm)

On registry `https://registry.npmjs.org/`, the "latest" version (v5.0.11) of dependency `travis-deploy-once` has the following deprecation notice:

`We recommend to use Travis Build Stages instead`

Marking the latest version of an npm package as deprecated results in the entire package being considered deprecated, so contact the package author you think this is a mistake.

Affected package file(s): `package.json`

If you don't care about this, you can close this issue and not be warned about `travis-deploy-once`'s deprecation again. If you would like to completely disable all future deprecation warnings then add the following to your config:

```
"suppressNotifications": ["deprecationWarningIssues"]
```

Start with package.json and inspect how travis-deploy-once is used in the project’s Travis configuration. Read the Travis Build Stages recommendation linked by the deprecation notice; done means the warning is addressed through a migration, or the issue is closed if no migration is wanted.
