* **New Feature**
* Decorators based on [@wycat's](https://github.com/wycats) [stage 1 proposal](https://github.com/wycats/javascript-decorators).
* Class property initializers based on [@jeffmo's](https://github.com/jeffmo) [stage 0 proposal](https://gist.github.com/jeffmo/054df782c05639da2adb).
* Export extensions based on [@leebyron's](https://github.com/leebyron) [stage 1 proposal](https://github.com/leebyron/ecmascript-more-export-from).
* UMD module formatter now supports globals.
* Add `es3.runtime`, `optimisation.react.inlineElements` and `optimisation.react.constantElements` transformers.
* Add stage option that replaces the experimental one.
* Allow ES7 transformer to be enabled via `optional` instead of only via `stage`.
* Infer string quotes to use in the code generator.
* Consider `export { foo as default };` to be the same as `export default foo;`.
* Add `nonStandard` option that can be set to `false` to remove parser support for JSX and Flow.
* Add `jsxPragma` option.
* Automatically generate CLI options based on internal API options.
* Add support for `.babelrc` on absolute paths.
* **Internal**
* Export `options` in browser API.
* Rewritten parser.
* Don't block hoist when runtime transformer is enabled in system module formatter.
* Rewritten the internal traversal and node replacement API to use "paths" that abstracts out node relationships.
* **Polish**
* JSX output is now more inline with the official JSX transformer.
* Hoist block scoping IIFE - this improves memory usage and performance.
* Better IIFE detection - references are now checked to see if they're referencing the binding we're searching for.
* Check for import reassignments in constants transformer.
* Make method definitions with expression bodies illegal.
* Save register cache on tick instead of `SIGINT`.
* Enable strict mode on babel-node eval flag.
* **Bug Fixes**
* Add support for live bindings. This change also increases the reliablity of export specifier renaming.
* Add support for super update and non equals assignment expressions.
* Rename shadow constructor binding in classes.
* Seed next iteration bindings with previous fresh bindings when reassinging loop block scoped variables.
* Fix new expression spread referencing the wrong constructor.
* Call `resolveModuleSource` on dynamic imports.
* Added `param` to list of duplicate declaration kinds.
* **Breaking Changes**
* The Babel playground has been removed.
* ES7 Abstract References have been removed.
* Experimental option has been removed in favor of a stage option.
