+## v6.18.0 (2016-10-24)
+
+#### :rocket: New Feature
+* `babel-generator`, `babel-plugin-transform-flow-strip-types`
+  * [#4697](https://github.com/babel/babel/pull/4697) Add variance node type and generate property variance annotations. ([@samwgoldman](https://github.com/samwgoldman))
+
+Check out the [flow docs](https://flowtype.org/docs/variance.html) for more info:
+
+```js
+type T = { +p: T };
+interface T { -p: T };
+declare class T { +[k:K]: V };
+class T { -[k:K]: V };
+class C2 { +p: T = e };
+```
+
+* `babel-core`, `babel-traverse`
+  * [#4746](https://github.com/babel/babel/pull/4746) Support ObjectExpression in static path evaluation. ([@motiz88](https://github.com/motiz88))
+
+```js
+// in
+['a' + 'b']: 10 * 20, 'z': [1, 2, 3]}
+// out
+{ab: 200, z: [1, 2, 3]}
+```
+
+* `babel-plugin-syntax-dynamic-import`, `babel-preset-stage-2`
+  * [#4699](https://github.com/babel/babel/pull/4699) [import()] Initial support for dynamic-import. ([@kesne](https://github.com/kesne))
+
+Parser support was added in https://github.com/babel/babylon/releases/tag/v6.12.0.
+
+Just the plugin to enable it in babel.
+
+```js
+// install
+$ npm install babel-plugin-syntax-dynamic-import --save-dev
+```
+
+or use the new `parserOpts`
+
+```js
+// .babelrc
+{
+  "parserOpts": {
+    "plugins": ['dynamicImport']
+  }
+}
+```
+
+* `babel-helper-builder-react-jsx`, `babel-plugin-transform-react-jsx`
+  * [#4655](https://github.com/babel/babel/pull/4655) Add `useBuiltIns` option to helper-builder-react-jsx. ([@existentialism](https://github.com/existentialism))
+
+Previously we added a `useBuiltIns` for object-rest-spread so that it use the native/built in version if you use a polyfill or have it supported natively.
+
+This change just uses the same option from the plugin to be applied with spread inside of jsx.
+
+```js
+// in
+var div = <Component {...props} foo="bar" />
+// out
+var div = React.createElement(Component, Object.assign({}, props, { foo: "bar" }));
+```
+
+* `babel-generator`, `babel-traverse`, `babel-types`
+  * [#4724](https://github.com/babel/babel/pull/4724) Add `EmptyTypeAnnotation`. ([@samwgoldman](https://github.com/samwgoldman))
+

+
+Added in flow [here](https://github.com/facebook/flow/commit/c603505583993aa953904005f91c350f4b65d6bd) and in babylon [here](https://github.com/babel/babylon/pull/171).
+
+```js
+function f<T>(x: empty): T {
+  return x;
+}
+f(); // nothing to pass...
+```
+
+* `babel-traverse`
+  * [#4758](https://github.com/babel/babel/pull/4758) Make getBinding ignore labels; add Scope#getLabel, Scope#hasLabel, Scope#registerLabel. ([@kangax](https://github.com/kangax))
+
+Track `LabeledStatement` separately (not part of bindings).

+
+```
+ReferenceError: [BABEL] /test.js: Unknown option: base.loose2. Check out http://babeljs.io/docs/usage/options/ for more information about options.
+
+A common cause of this error is the presence of a configuration options object without the corresponding preset name. Example:
+
+Invalid:
+  `{ presets: [{option: value}] }`
+Valid:
+  `{ presets: ["pluginName", {option: value}] }`
+
+For more detailed information on preset configuration, please see http://babeljs.io/docs/plugins/#pluginpresets-options.
