-### Language features
-* Added support for [configuration-specific imports](https://github.com/munificent/dep-interface-libraries/blob/master/Proposal.md).
-  On the VM and dart2js, they can be enabled with `--conditional-directives`.

-  The analyzer requires an additional option in an `options` file:
-  ```yaml
-  analyzer:
-    language:
-      enableConditionalDirectives: true
-  ```
-  Then run the analyzer with `--options=<path-to-options-file>`.
