+2. License Grants and Conditions
+--------------------------------
+
+2.1. Grants
+
+Each Contributor hereby grants You a world-wide, royalty-free,
+non-exclusive license:
+
+(a) under intellectual property rights (other than patent or trademark)
+    Licensable by such Contributor to use, reproduce, make available,
+    modify, display, perform, distribute, and otherwise exploit its
+    Contributions, either on an unmodified basis, with Modifications, or
+    as part of a Larger Work; and
+
+(b) under Patent Claims of such Contributor to make, use, sell, offer
+    for sale, have made, import, and otherwise transfer either its
+    Contributions or its Contributor Version.
+
+2.2. Effective Date
+
+The licenses granted in Section 2.1 with respect to any Contribution
+become effective for each Contribution on the date the Contributor first
+distributes such Contribution.
+
+2.3. Limitations on Grant Scope
+
+The licenses granted in this Section 2 are the only rights granted under
+this License. No additional rights or licenses will be implied from the
+distribution or licensing of Covered Software under this License.
+Notwithstanding Section 2.1(b) above, no patent license is granted by a
+Contributor:
+
+(a) for any code that a Contributor has removed from Covered Software;
+    or
+
+(b) for infringements caused by: (i) Your and any other third party's
+    modifications of Covered Software, or (ii) the combination of its
+    Contributions with other software (except as part of its Contributor
+    Version); or
+
+(c) under Patent Claims infringed by Covered Software in the absence of
+    its Contributions.
+
+This License does not grant any rights in the trademarks, service marks,
+or logos of any Contributor (except as may be necessary to comply with
+the notice requirements in Section 3.4).
+
+2.4. Subsequent Licenses
+
+No Contributor makes additional grants as a result of Your choice to
+distribute the Covered Software under a subsequent version of this
+License (see Section 10.2) or under the terms of a Secondary License (if
+permitted under the terms of Section 3.3).
+
+2.5. Representation
+
+Each Contributor represents that the Contributor believes its
+Contributions are its original creation(s) or it has sufficient rights
+to grant the rights to its Contributions conveyed by this License.
+
+2.6. Fair Use
+
+This License is not intended to limit any rights You have under
+applicable copyright doctrines of fair use, fair dealing, or other
+equivalents.
+
+2.7. Conditions
+
+Sections 3.1, 3.2, 3.3, and 3.4 are conditions of the licenses granted
+in Section 2.1.
+
+3. Responsibilities
+-------------------
+
+3.1. Distribution of Source Form
+
+All distribution of Covered Software in Source Code Form, including any
+Modifications that You create or to which You contribute, must be under
+the terms of this License. You must inform recipients that the Source
+Code Form of the Covered Software is governed by the terms of this
+License, and how they can obtain a copy of this License. You may not
+attempt to alter or restrict the recipients' rights in the Source Code
+Form.
+
+3.2. Distribution of Executable Form
+
+If You distribute Covered Software in Executable Form then:
+
+(a) such Covered Software must also be made available in Source Code
+    Form, as described in Section 3.1, and You must inform recipients of
+    the Executable Form how they can obtain a copy of such Source Code
+    Form by reasonable means in a timely manner, at a charge no more
+    than the cost of distribution to the recipient; and
+
+(b) You may distribute such Executable Form under the terms of this
+    License, or sublicense it under different terms, provided that the
+    license for the Executable Form does not attempt to limit or alter
+    the recipients' rights in the Source Code Form under this License.
+
+3.3. Distribution of a Larger Work
+
+You may create and distribute a Larger Work under terms of Your choice,
+provided that You also comply with the requirements of this License for
+the Covered Software. If the Larger Work is a combination of Covered
+Software with a work governed by one or more Secondary Licenses, and the
+Covered Software is not Incompatible With Secondary Licenses, this
+License permits You to additionally distribute such Covered Software
+under the terms of such Secondary License(s), so that the recipient of
+the Larger Work may, at their option, further distribute the Covered
+Software under the terms of either this License or such Secondary
+License(s).
+
+3.4. Notices
+
+You may not remove or alter the substance of any license notices
+(including copyright notices, patent notices, disclaimers of warranty,
+or limitations of liability) contained within the Source Code Form of
+the Covered Software, except that You may alter any license notices to
+the extent required to remedy known factual inaccuracies.
+
+3.5. Application of Additional Terms
+
+You may choose to offer, and to charge a fee for, warranty, support,
+indemnity or liability obligations to one or more recipients of Covered
+Software. However, You may do so only on Your own behalf, and not on
+behalf of any Contributor. You must make it absolutely clear that any
+such warranty, support, indemnity, or liability obligation is offered by
+You alone, and You hereby agree to indemnify every Contributor for any
+liability incurred by such Contributor as a result of warranty, support,
+indemnity or liability terms You offer. You may include additional
+disclaimers of warranty and limitations of liability specific to any
+jurisdiction.
+
+4. Inability to Comply Due to Statute or Regulation
+---------------------------------------------------
+
+If it is impossible for You to comply with any of the terms of this
+License with respect to some or all of the Covered Software due to
+statute, judicial order, or regulation then You must: (a) comply with
+the terms of this License to the maximum extent possible; and (b)
+describe the limitations and the code they affect. Such description must
+be placed in a text file included with all distributions of the Covered
+Software under this License. Except to the extent prohibited by statute
+or regulation, such description must be sufficiently detailed for a
+recipient of ordinary skill to be able to understand it.
+
+5. Termination
+--------------
+
+5.1. The rights granted under this License will terminate automatically
+if You fail to comply with any of its terms. However, if You become
+compliant, then the rights granted under this License from a particular
+Contributor are reinstated (a) provisionally, unless and until such
+Contributor explicitly and finally terminates Your grants, and (b) on an
+ongoing basis, if such Contributor fails to notify You of the
+non-compliance by some reasonable means prior to 60 days after You have
+come back into compliance. Moreover, Your grants from a particular
+Contributor are reinstated on an ongoing basis if such Contributor
+notifies You of the non-compliance by some reasonable means, this is the
+first time You have received notice of non-compliance with this License
+from such Contributor, and You become compliant prior to 30 days after
+Your receipt of the notice.
+
+5.2. If You initiate litigation against any entity by asserting a patent
+infringement claim (excluding declaratory judgment actions,
+counter-claims, and cross-claims) alleging that a Contributor Version
+directly or indirectly infringes any patent, then the rights granted to
+You by any and all Contributors for the Covered Software under Section
+2.1 of this License shall terminate.
+
+5.3. In the event of termination under Sections 5.1 or 5.2 above, all
+end user license agreements (excluding distributors and resellers) which
+have been validly granted by You or Your distributors under this License
+prior to termination shall survive termination.

+# gstwebrtc-api
+
+[![License: MPL 2.0](https://img.shields.io/badge/License-MPL_2.0-brightgreen.svg)](https://opensource.org/licenses/MPL-2.0)
+
+Javascript API used to integrate GStreamer WebRTC streams produced and consumed by webrtcsink and webrtcsrc elements
+into a web browser or a mobile WebView.
+
+This API allows a complete 360º interconnection between GStreamer and web interfaces for realtime streaming using the
+WebRTC protocol.
+
+This API is released under the Mozilla Public License Version 2.0 (MPL-2.0) that can be found in the LICENSE-MPL-2.0
+file or at https://opensource.org/licenses/MPL-2.0
+
+Copyright (C) 2022 Igalia S.L. <<info@igalia.com>><br>
+Author: Loïc Le Page <<llepage@igalia.com>>
+
+It includes external source code from [webrtc-adapter](https://github.com/webrtcHacks/adapter) that is embedded with
+the API. The webrtc-adapter BSD 3-Clause license is available at
+https://github.com/webrtcHacks/adapter/blob/master/LICENSE.md
+
+Webrtc-adapter is Copyright (c) 2014, The WebRTC project authors, All rights reserved.<br>
+Copyright (c) 2018, The adapter.js project authors, All rights reserved.
+
+## Building the API
+
+The GstWebRTC API uses [Webpack](https://webpack.js.org/) to bundle all source files and dependencies together.
+
+You only need to install [Node.js](https://nodejs.org/en/) to run all commands.
+
+On first time, install the dependencies by calling:
+```shell
+$ npm install
+```
+
+Then build the bundle by calling:
+```shell
+$ npm run make
+```
+
+It will build and compress the code into the *dist/* folder, there you will find the following files:
+- *gstwebrtc-api-[version].min.js* which is the only file you need to include in your web application to use the API,
+  if you are manually adding the .js file to your webpage. It already embeds all dependencies.
+- *gstwebrtc-api-[version].min.js.map* which is useful for debugging the API code, you need to put it in the same
+  folder as the API script on your web server if you want to allow debugging, else you can just ignore it.
+- *gstwebrtc-api-[version].esm.js, which is the ES module variant of this library. You probably don't need to use
+  this directly - it will be automatically used by your build system if you install this package via npm. See below.
+- *gstwebrtc-api-[version].esm.js.map* which is the source map for the ES module variant mentioned above.
+
+The API documentation is created into the *docs/* folder. It is automatically created when building the whole API.
+
+If you want to build the documentation only, you can call:
+```shell
+$ npm run docs
+```
+
+If you only want to build the API without the documentation, you can call:
+```shell
+$ npm run build
+```
+
+## Packaging the API
+
+You can create a portable package of the API by calling:
+```shell
+$ npm pack
+```
+
+It will create a *gstwebrtc-api-[version].tgz* file that contains all source code, documentation and built API. This
+portable package can be installed as a dependency in any Node.js project by calling:
+```shell
+$ npm install gstwebrtc-api-[version].tgz
+```
+
+## Testing and debugging the API
+
+To easily test and debug the GstWebRTC API, you just need to:
+1. launch the webrtc signalling server by calling (from the repository *gst-plugins-rs* root folder):
+   ```shell
+   $ cargo run --bin gst-webrtc-signalling-server
+   ```
+2. launch the GstWebRTC API server by calling (from the *net/webrtc/gstwebrtc-api* sub-folder):
+   ```shell
+   $ npm start
+   ```
+
+It will launch a local HTTPS server listening on port 9090 and using an automatically generated self-signed
+certificate.
+
+With this server you can test the reference example shipped in *index.html* from a web browser on your local computer
+or a mobile device.
+
+## Interconnect with GStreamer pipelines
+
+Once the signalling and gstwebrtc-api servers launched, you can interconnect the streams produced and consumed from
+the web browser with GStreamer pipelines using the webrtcsink and webrtcsrc elements.
+
+### Consume a WebRTC stream produced by the gstwebrtc-api
+
+On the web browser side, click on the *Start Capture* button and give access to the webcam. The gstwebrtc-api will
+start producing a video stream.
+
+The signalling server logs will show the registration of a new producer with the same *peer_id* as the *Client ID*
+that appears on the webpage.
+
+Then launch the following GStreamer pipeline:
+```shell
+$ gst-launch-1.0 playbin3 uri=gstwebrtc://[signalling server]?peer-id=[client ID of the producer]
+```
+
+Using the local signalling server, it will look like this:
+```shell
+$ gst-launch-1.0 playbin3 uri=gstwebrtc://127.0.0.1:8443?peer-id=e54e5d6b-f597-4e8f-bc96-2cc3765b6567
+```
+
+The underlying *uridecodebin* element recognizes the *gstwebrtc://* scheme as a WebRTC stream compatible with the
+gstwebrtc-api and will correctly use a *webrtcsrc* element to manage this stream.
+
+The *gstwebrtc://* scheme is used for normal WebSocket connections to the signalling server, and the *gstwebrtcs://*
+scheme for secured connections over SSL or TLS.
+
+### Produce a GStreamer WebRTC stream consumed by the gstwebrtc-api
+
+Launch the following GStreamer pipeline:
+```shell
+$ gst-launch-1.0 videotestsrc ! agingtv ! webrtcsink meta="meta,name=native-stream"
+```
+
+By default *webrtcsink* element uses *ws://127.0.0.1:8443* for the signalling server address, so there is no need
+for more arguments. If you're hosting the signalling server elsewhere, you can specify its address by adding
+`signaller::uri="ws[s]://[signalling server]"` to the list of *webrtcsink* properties.
+
+Once the GStreamer pipeline launched, you will see the registration of a new producer in the logs of the signalling
+server and a new remote stream, with the name *native-stream*, will appear on the webpage.
+
+You just need to click on the corresponding entry to connect as a consumer to the remote native stream.
+
+### Produce a GStreamer interactive WebRTC stream with remote control
+
+Launch the following GStreamer pipeline:
+```shell
+$ gst-launch-1.0 wpesrc location=https://gstreamer.freedesktop.org/documentation ! queue ! webrtcsink enable-control-data-channel=true meta="meta,name=web-stream"
+```
+
+Once the GStreamer pipeline launched, you will see a new producer with the name *web-stream*. When connecting to this
+producer you will see the remote rendering of the web page. You can interact remotely with this web page, controls are
+sent through a special WebRTC data channel while the rendering is done remotely by the
+[wpesrc](https://gstreamer.freedesktop.org/documentation/wpe/wpesrc.html) element.

+
+> Wrap words to a specified length.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install --save word-wrap
+```
+
+## Usage
+
+```js
+var wrap = require('word-wrap');
+
+wrap('Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat.');
+```
+
+Results in:
+
+```
+  Lorem ipsum dolor sit amet, consectetur adipiscing
+  elit, sed do eiusmod tempor incididunt ut labore
+  et dolore magna aliqua. Ut enim ad minim veniam,
+  quis nostrud exercitation ullamco laboris nisi ut
+  aliquip ex ea commodo consequat.
+```
+
+## Options

+
+### options.width
+
+Type: `Number`
+
+Default: `50`
+
+The width of the text before wrapping to a new line.
+
+**Example:**
+
+```js
+wrap(str, {width: 60});
+```
+
+### options.indent
+
+Type: `String`
+
+Default: `` (none)
+
+The string to use at the beginning of each line.
+
+**Example:**
+
+```js
+wrap(str, {indent: '      '});
+```
+
+### options.newline
+
+Type: `String`
+
+Default: `\n`
+
+The string to use at the end of each line.
+
+**Example:**
+
+```js
+wrap(str, {newline: '\n\n'});
+```
+
+### options.escape
+
+Type: `function`
+
+Default: `function(str){return str;}`
+
+An escape function to run on each line after splitting them.
+
+**Example:**
+
+```js
+var xmlescape = require('xml-escape');
+wrap(str, {
+  escape: function(string){
+    return xmlescape(string);
+  }
+});
+```
+
+### options.trim
+
+Type: `Boolean`
+
+Default: `false`
+
+Trim trailing whitespace from the returned string. This option is included since `.trim()` would also strip the leading indentation from the first line.
+
+**Example:**
+
+```js
+wrap(str, {trim: true});
+```
+
+### options.cut
+
+Type: `Boolean`
+
+Default: `false`
+
+Break a word between any two letters when the word is longer than the specified width.
+
+**Example:**
+
+```js
+wrap(str, {cut: true});
+```

+
+## 6.16.0 (2017-02-23)
+
+### :rocket: New Feature
+
+***ESTree*** compatibility as plugin ([#277](https://github.com/babel/babylon/pull/277)) (Daniel Tschinder)
+
+We finally introduce a new compatibility layer for ESTree. To put babylon into ESTree-compatible mode the new plugin `estree` can be enabled. In this mode the parser will output an AST that is compliant to the specs of [ESTree](https://github.com/estree/estree/)
+
+We highly recommend everyone who uses babylon outside of babel to use this plugin. This will make it much easier for users to switch between different ESTree-compatible parsers. We so far tested several projects with different parsers and exchanged their parser to babylon and in nearly all cases it worked out of the box. Some other estree-compatible parsers include `acorn`, `esprima`, `espree`, `flow-parser`, etc.
+
+To enable `estree` mode simply add the plugin in the config:
+```json
+{
+  "plugins": [ "estree" ]
+}
+```
+
+If you want to migrate your project from non-ESTree mode to ESTree, have a look at our [Readme](https://github.com/babel/babylon/#output), where all deviations are mentioned.
+
+Add a parseExpression public method ([#213](https://github.com/babel/babylon/pull/213)) (jeromew)
+
+Babylon exports a new function to parse a single expression
+
+```js
+import { parseExpression } from 'babylon';
+
+const ast = parseExpression('x || y && z', options);
+```
+
+The returned AST will only consist of the expression. The options are the same as for `parse()`
+
+Add startLine option ([#346](https://github.com/babel/babylon/pull/346)) (Raphael Mu)
+
+A new option was added to babylon allowing to change the initial linenumber for the first line which is usually `1`.
+Changing this for example to `100` will make line `1` of the input source to be marked as line `100`, line `2` as `101`, line `3` as `102`, ...
+
+Function predicate declaration ([#103](https://github.com/babel/babylon/pull/103)) (Panagiotis Vekris)
+
+Added support for function predicates which flow introduced in version 0.33.0
+
+```js
+declare function is_number(x: mixed): boolean %checks(typeof x === "number");
+```
+
+Allow imports in declare module ([#315](https://github.com/babel/babylon/pull/315)) (Daniel Tschinder)
+
+Added support for imports within module declarations which flow introduced in version 0.37.0
+
+```js
+declare module "C" {
+  import type { DT } from "D";
+  declare export type CT = { D: DT };
+}
+```
+
+### :eyeglasses: Spec Compliance
+
+Forbid semicolons after decorators in classes ([#352](https://github.com/babel/babylon/pull/352)) (Kevin Gibbons)
+
+This example now correctly throws an error when there is a semicolon after the decorator:
+
+```js
+class A {
+@a;
+foo(){}
+}
+```
+
+Keywords are not allowed as local specifier ([#307](https://github.com/babel/babylon/pull/307)) (Daniel Tschinder)
+
+Using keywords in imports is not allowed anymore:
+
+```js
+import { default } from "foo";
+import { a as debugger } from "foo";
+```
+
+Do not allow overwritting of primitive types ([#314](https://github.com/babel/babylon/pull/314)) (Daniel Tschinder)
+
+In flow it is now forbidden to overwrite the primitive types `"any"`, `"mixed"`, `"empty"`, `"bool"`, `"boolean"`, `"number"`, `"string"`, `"void"` and `"null"` with your own type declaration.
+
+Disallow import type { type a } from … ([#305](https://github.com/babel/babylon/pull/305)) (Daniel Tschinder)
+
+The following code now correctly throws an error
+
+```js
+import type { type a } from "foo";
+```
+
+Don't parse class properties without initializers when classProperties is disabled and Flow is enabled ([#300](https://github.com/babel/babylon/pull/300)) (Andrew Levine)
+
+Ensure that you enable the `classProperties` plugin in order to enable correct parsing of class properties. Prior to this version it was possible to parse them by enabling the `flow` plugin but this was not intended the behaviour.
+
+If you enable the flow plugin you can only define the type of the class properties, but not initialize them.
+
+Fix export default async function to be FunctionDeclaration ([#324](https://github.com/babel/babylon/pull/324)) (Daniel Tschinder)
+
+Parsing the following code now returns a `FunctionDeclaration` AST node instead of `FunctionExpression`.
+
+```js
+export default async function bar() {};
+```
+

+
+### :eyeglasses: Spec Compliance
+
+Add support for Flow shorthand import type ([#267](https://github.com/babel/babylon/pull/267)) (Jeff Morrison)
+
+This change implements flows new shorthand import syntax
+and where previously you had to write this code:
+
+```js
+import {someValue} from "blah";
+import type {someType} from "blah";
+import typeof {someOtherValue} from "blah";
+```
+
+you can now write it like this:
+
+```js
+import {
+  someValue,
+  type someType,
+  typeof someOtherValue,
+} from "blah";
+```
+
+For more information look at [this](https://github.com/facebook/flow/pull/2890) pull request.
+
+flow: allow leading pipes in all positions ([#256](https://github.com/babel/babylon/pull/256)) (Vladimir Kurchatkin)
+
+This change now allows a leading pipe everywhere types can be used:
+```js
+var f = (x): | 1 | 2 => 1;
+```
+
+Throw error when exporting non-declaration ([#241](https://github.com/babel/babylon/pull/241)) (Kai Cataldo)
+
+Previously babylon parsed the following exports, although they are not valid:
+```js
+export typeof foo;
+export new Foo();
+export function() {};
+export for (;;);
+export while(foo);
+```
+
+### :bug: Bug Fix
+
+Don't set inType flag when parsing property names ([#266](https://github.com/babel/babylon/pull/266)) (Vladimir Kurchatkin)
+
+This fixes parsing of this case:
+
+```js
+const map = {
+  [age <= 17] : 'Too young'
+};
+```
+
+Fix source location for JSXEmptyExpression nodes (fixes #248) ([#249](https://github.com/babel/babylon/pull/249)) (James Long)
+
+The following case produced an invalid AST
+```js
+<div>{/* foo */}</div>
+```
+
+Use fromCodePoint to convert high value unicode entities ([#243](https://github.com/babel/babylon/pull/243)) (Ryan Duffy)
+
+When high value unicode entities (e.g. 💩) were used in the input source code they are now correctly encoded in the resulting AST.
+
+Rename folder to avoid Windows-illegal characters ([#281](https://github.com/babel/babylon/pull/281)) (Ryan Plant)
+
+Allow this.state.clone() when parsing decorators ([#262](https://github.com/babel/babylon/pull/262)) (Alex Rattray)

+Temporary rollback for erroring on trailing comma with spread (#154) (Henry Zhu)

+## v6.11.3 (2016-10-01)
+
+### :eyeglasses: Spec Compliance
+
+Add static errors for object rest (#149) ([@danez](https://github.com/danez))
+
+> https://github.com/sebmarkbage/ecmascript-rest-spread
+
+Object rest copies the *rest* of properties from the right hand side `obj` starting from the left to right.
+
+```js
+let { x, y, ...z } =  { x: 1, y: 2, z: 3 };
+// x = 1
+// y = 2
+// z = { z: 3 }
+```
+
+#### New Syntax Errors:
+
+**SyntaxError**: The rest element has to be the last element when destructuring (1:10)
+```bash
+> 1 | let { ...x, y, z } = { x: 1, y: 2, z: 3};
+    |           ^
+# Previous behavior:
+# x = { x: 1, y: 2, z: 3 }
+# y = 2
+# z = 3
+```
+
+Before, this was just a more verbose way of shallow copying `obj` since it doesn't actually do what you think.
+
+**SyntaxError**: Cannot have multiple rest elements when destructuring (1:13)
+
+```bash
+> 1 | let { x, ...y, ...z } = { x: 1, y: 2, z: 3};
+    |              ^
+# Previous behavior:
+# x = 1
+# y = { y: 2, z: 3 }
+# z = { y: 2, z: 3 }
+```
+
+Before y and z would just be the same value anyway so there is no reason to need to have both.
+
+**SyntaxError**: A trailing comma is not permitted after the rest element (1:16)
+
+```js
+let { x, y, ...z, } = obj;
+```
+
+The rationale for this is that the use case for trailing comma is that you can add something at the end without affecting the line above. Since a RestProperty always has to be the last property it doesn't make sense.

+
+## 6.10.0 (2016-09-19)
+
+> We plan to include some spec compliance bugs in patch versions. An example was the multiple default exports issue.
+
+### Spec Compliance
+
+* Implement ES2016 check for simple parameter list in strict mode ([#106](https://github.com/babel/babylon/pull/106)) (Timothy Gu)
+
+> It is a Syntax Error if ContainsUseStrict of FunctionBody is true and IsSimpleParameterList of FormalParameters is false. https://tc39.github.io/ecma262/2016/#sec-function-definitions-static-semantics-early-errors
+
+More Context: [tc39-notes](https://github.com/rwaldron/tc39-notes/blob/master/es7/2015-07/july-29.md#611-the-scope-of-use-strict-with-respect-to-destructuring-in-parameter-lists)
+
+For example:
+
+```js
+// this errors because it uses destructuring and default parameters
+// in a function with a "use strict" directive
+function a([ option1, option2 ] = []) {
+  "use strict";
+}
+ ```
+
+The solution would be to use a top level "use strict" or to remove the destructuring or default parameters when using a function + "use strict" or to.
+
+### New Feature
+
+* Exact object type annotations for Flow plugin ([#104](https://github.com/babel/babylon/pull/104)) (Basil Hosmer)
+
+Added to flow in https://github.com/facebook/flow/commit/c710c40aa2a115435098d6c0dfeaadb023cd39b8
+
+Looks like:
+
+```js
+var a : {| x: number, y: string |} = { x: 0, y: 'foo' };
+```
+
+### Bug Fixes
+
+* Include `typeParameter` location in `ArrowFunctionExpression` ([#126](https://github.com/babel/babylon/pull/126)) (Daniel Tschinder)
+* Error on invalid flow type annotation with default assignment ([#122](https://github.com/babel/babylon/pull/122)) (Dan Harper)

+* Fix Contributing guidelines [skip ci] (Daniel Tschinder)
+
+## 6.9.2 (2016-09-09)

+
+## 6.9.1 (2016-08-23)

+- The param list for type parameter declarations now consists of `TypeParameter` nodes
+- New `TypeParameter` AST Node (replaces using the `Identifier` node before)
+
+```
+interface TypeParameter <: Node {
+  bound: TypeAnnotation;
+  default: TypeAnnotation;
+  name: string;
+  variance: "plus" | "minus";
+}
+```
+
+## 6.8.0 (2016-05-02)
+
+#### New Feature
+
+##### Parse Method Parameter Decorators ([#12](https://github.com/babel/babylon/pull/12))
+
+> [Method Parameter Decorators](https://goo.gl/8MmCMG) is now a TC39 [stage 0 proposal](https://github.com/tc39/ecma262/blob/master/stage0.md).
+
+Examples:
+
+```js
+class Foo {
+  constructor(@foo() x, @bar({ a: 123 }) @baz() y) {}
+}
+
+export default function func(@foo() x, @bar({ a: 123 }) @baz() y) {}
+
+var obj = {
+  method(@foo() x, @bar({ a: 123 }) @baz() y) {}
+};
+```
+
+##### Parse for-await statements (w/ `asyncGenerators` plugin) ([#17](https://github.com/babel/babylon/pull/17))
+
+There is also a new node type, `ForAwaitStatement`.
+
+> [Async generators and for-await](https://github.com/tc39/proposal-async-iteration) are now a [stage 2 proposal](https://github.com/tc39/ecma262#current-proposals).
+
+Example:
+
+```js
+async function f() {
+  for await (let x of y);
+}
+```
