+## 6.5.0 (2016-02-07)
+
+Happy Superbowl Sunday! There's many contributors (17 + core) this release!
+
+### A traversal per preset
+
+[@DmitrySoshnikov](https://github.com/DmitrySoshnikov) added a new option you can put in your `.babelrc`!
+
+```js
+{
+  passPerPreset: true,
+  presets: [
+    {
+      plugins: ['plugin-1']
+    },
+    'preset-2',
+    {
+      plugins: ['plugin-2']
+    }
+  ]
+}
+// this will create 3 traversals
+```
+
+`passPerPreset: true` will modify how babel traverses through plugins. Instead of a single traversal in which all plugins/presets are merged together, each preset will get their own traversal.
+
+This allows users to have a specific order to how presets/plugins are applied and can help avoid potential collisions between plugins (and probably some known issues).
+
+Depending on usage, we will switch the way this is used to instead define a explicit preset-level config flag (rather than the current global one).
+

+
+### More Speeeeeeed

+
+[@gzzhanghao](https://github.com/gzzhanghao) made some awesome changes to improve our code generator's performance (`babel-generator`). The original issue is [here](https://phabricator.babeljs.io/T6884).
+
+Based on his test (on parsing `jquery.js`), performance improved ~3x.
+
+```
+===== origin/master (ms) =====
+babylon 265
+babel generator 2238 <-- old
+acorn 107
+escodegen 355
+esprima 95
+escodegen 322
+===== Optimized (ms) =====
+babylon 296
+babel generator 662 <-- new
+acorn 113
+escodegen 355
+esprima 106
+escodegen 317
+```
+
+A big change had to do with keeping `this.last` as an instance variable in the buffer instead of `this.buf[this.buf.length -1]`.
+
+> You can read more about his changes [here](https://github.com/babel/babel/pull/3283#discussion-diff-50198857).  Hoping to see more PR's like this!
+
+We will try to setup some perf tests soon to track these stats for the future (or you can help!). 
+
+#### New Feature
+
++ `babel-core`
+  + [#3168](https://github.com/babel/babel/pull/3168) Use the `babelrc` option in `babel-register`. ([@CrocoDillon](https://github.com/CrocoDillon))
++ `babel-core`
+  + [#3281](https://github.com/babel/babel/pull/3281) `passPerPreset` option in `.babelrc`: if `true`, babel will create a new traversal for each preset. ([@DmitrySoshnikov](https://github.com/DmitrySoshnikov))
++ `babel-helper-transform-fixture-test-runner`, `babel-plugin-transform-react-jsx-source`
+  + [#3285](https://github.com/babel/babel/pull/3285) Hoist the current file name (an absolute path) for `transform-react-jsx-source` . ([@frantic](https://github.com/frantic))
+  
+This plugin (useful for tooling) will turn
+
+```js
+// this/file.js
+<sometag />
+```
+
+into 
+
+```js
+var _jsxFileName = "this/file.js"; // the output will be an absolute path
+var x = <sometag __source={{
+  fileName: _jsxFileName,
+  lineNumber: 1
+}} />;
+```
+
++ `babel-template`
+  + [#3304](https://github.com/babel/babel/pull/3304) Allow passing in `babylon` options into `babel-template`. (issue [T7046](phabricator.babeljs.io/T7046)) ([@jamestalmage](https://github.com/jamestalmage))
++ `babel-core`
+  + [#3313](https://github.com/babel/babel/pull/3313) Add `babel.analyze` - an api sugar for getting back metadata from babel. ([@kittens](https://github.com/kittens))
+
+```js
+// analyse not analyze :D
+// usage
+babel.analyse("foobar;", {}, {
+  Program: function (path) {
+    path.mark("category", "foobar");
+  }
+}).marked[0].message // outputs "foobar"
+```
+
++ `babylon`
+  + [#3319](https://github.com/babel/babel/pull/3319) Add support for leading pipes in Flow type alias RHS syntax ([@jeffmo](https://github.com/jeffmo))
+  
+```js
+// allows for either `|` or `&`
+type union =
+ | {type: "A"}
+ | {type: "B"}
+;
+```
+
+> This was added in [flow](https://github.com/facebook/flow/) in [`7fb56ee9d8`](https://github.com/facebook/flow/commit/7fb56ee9d87517973b4ab32f180ff968c99dded5).
