babel-preset-env - npm Package Compare versions

Comparing version 1.6.0 to 1.6.1

CHANGELOG.md

 # Changelog
 
+## v1.6.1 (2017-10-17)
+
+### :bug: Bug Fix
+
+- Update compat table to fix two small issues ([#445](https://github.com/babel/babel-preset-env/pull/445)) (@danez)
+
+ES6 destructuring is not fully supported in Edge 15 and the polyfill required again. `es6.math.imul` is supported on Android as of version 4.4
+
+- Add polyfills for ES6 static Object methods ([#441](https://github.com/babel/babel-preset-env/pull/441)) (@danez)
+
+Functions such as `Object.keys`, `Object.freeze`, ...do already exist in ES5, but their behaviour changed in ES6. `babel-preset-env` with `builtIns: true` now adds the core-js polyfills for this methods if the browser only supports the ES5 variant of the version (like IE11 for example)
+
+- Normalize module format of plugins/built-ins data ([#376](https://github.com/babel/babel-preset-env/pull/376)) (@rtsao)
