[Version Diff](https://github.com/swagger-api/swagger-ui/compare/v3.0.17...v3.0.18)

**Interface changes**: None

- Locked dependency for `swagger-client` to exact version. This should be a transparent change.
- Removed `babel-polyfill` dependency. This should make it easier to use Swagger-UI in projects that _also_ use `babel-polyfill`. (via 2599)
- Fixed untranspiled arrow function syntax in `swagger-ui-dist-package/absolute-path.js` that would cause problems with Node < 4.0.0 (via 3264)
- Explicitly pinned `yaml-js0.2.0` in order to pick up an upstream fix that should improve our compatibility with projects that use Webpack 2.0+ (via 3281)
- Fixed a bug where empty Markdown source text would cause the UI to render `undefined` as text.

[Version Diff](https://github.com/swagger-api/swagger-ui/compare/v3.0.16...v3.0.17)

**Interface changes:** None.

- Fixes an error in `swagger-ui-dist` (see 3253).
