## Changelog
##### 2.0.0 - 2015.12.24
- added implementations and fixes [Typed Arrays](https://github.com/zloirock/core-js#ecmascript-6-typed-arrays)-related features
- `ArrayBuffer`, `ArrayBuffer.isView`, `ArrayBuffer#slice`
- `DataView` with all getter / setter methods
- `Int8Array`, `Uint8Array`, `Uint8ClampedArray`, `Int16Array`, `Uint16Array`, `Int32Array`, `Uint32Array`, `Float32Array` and `Float64Array` constructors
- `%TypedArray%.{for, of}`, `%TypedArray%#{copyWithin, every, fill, filter, find, findIndex, forEach, indexOf, includes, join, lastIndexOf, map, reduce, reduceRight, reverse, set, slice, some, sort, subarray, values, keys, entries, @@iterator, ...}`
- added [`System.global`](https://github.com/zloirock/core-js#ecmascript-7-proposals), [proposal](https://github.com/tc39/proposal-global), [November TC39 meeting](https://github.com/rwaldron/tc39-notes/tree/master/es7/2015-11/nov-19.md#systemglobal-jhd)
- added [`Error.isError`](https://github.com/zloirock/core-js#ecmascript-7-proposals), [proposal](https://github.com/ljharb/proposal-is-error), [November TC39 meeting](https://github.com/rwaldron/tc39-notes/tree/master/es7/2015-11/nov-19.md#jhd-erroriserror)
- added [`Math.{iaddh, isubh, imulh, umulh}`](https://github.com/zloirock/core-js#ecmascript-7-proposals), [proposal](https://gist.github.com/BrendanEich/4294d5c212a6d2254703)
- `RegExp.escape` moved from the `es7` to the non-standard `core` namespace, [July TC39 meeting](https://github.com/rwaldron/tc39-notes/blob/master/es7/2015-07/july-28.md#62-regexpescape) - too slow, but it's condition of stability, [#116](https://github.com/zloirock/core-js/issues/116)
- [`Promise`](https://github.com/zloirock/core-js#ecmascript-6-promise)
- some performance optimisations
- added basic support [`rejectionHandled` event / `onrejectionhandled` handler](https://github.com/zloirock/core-js#unhandled-rejection-tracking) to the polyfill
- removed usage `@@species` from `Promise.{all, race}`, [November TC39 meeting](https://github.com/rwaldron/tc39-notes/tree/master/es7/2015-11/nov-18.md#conclusionresolution-2)
- some improvements [collections polyfills](https://github.com/zloirock/core-js#ecmascript-6-collections)
- `O(1)` and preventing possible leaks with frozen keys, [#134](https://github.com/zloirock/core-js/issues/134)
- correct observable state object keys
- renamed `String#{padLeft, padRight}` -> [`String#{padStart, padEnd}`](https://github.com/zloirock/core-js#ecmascript-7-proposals), [proposal](https://github.com/tc39/proposal-string-pad-start-end), [November TC39 meeting](https://github.com/rwaldron/tc39-notes/tree/master/es7/2015-11/nov-17.md#conclusionresolution-2) (they want to rename it on each meeting?O_o), [#132](https://github.com/zloirock/core-js/issues/132)
- added [`String#{trimStart, trimEnd}` as aliases for `String#{trimLeft, trimRight}`](https://github.com/zloirock/core-js#ecmascript-7-proposals), [proposal](https://github.com/sebmarkbage/ecmascript-string-left-right-trim), [November TC39 meeting](https://github.com/rwaldron/tc39-notes/tree/master/es7/2015-11/nov-17.md#conclusionresolution-2)
- added [annex B HTML methods](https://github.com/zloirock/core-js#ecmascript-6-string) - ugly, but also [the part of the spec](http://www.ecma-international.org/ecma-262/6.0/#sec-string.prototype.anchor)
- added little fix for [`Date#toString`](https://github.com/zloirock/core-js#ecmascript-6-date) - `new Date(NaN).toString()` [should be `'Invalid Date'`](http://www.ecma-international.org/ecma-262/6.0/#sec-todatestring)
- added [`{keys, values, entries, @@iterator}` methods to DOM collections](https://github.com/zloirock/core-js#iterable-dom-collections) which should have [iterable interface](https://heycam.github.io/webidl/#idl-iterable) or should be [inherited from `Array`](https://heycam.github.io/webidl/#LegacyArrayClass) - `NodeList`, `DOMTokenList`, `MediaList`, `StyleSheetList`, `CSSRuleList`.
- removed Mozilla `Array` generics - [deprecated and will be removed from FF](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array#Array_generic_methods), [looks like strawman is dead](http://wiki.ecmascript.org/doku.php?id=strawman:array_statics), available [alternative shim](https://github.com/plusdude/array-generics)
- removed `core.log` module
- CommonJS API
- added entry points for [virtual methods](https://github.com/zloirock/core-js#commonjs-and-prototype-methods-without-global-namespace-pollution)
- added entry points for [stages proposals](https://github.com/zloirock/core-js#ecmascript-7-proposals)
- some other minor changes
- [custom build from external scripts](https://github.com/zloirock/core-js#custom-build-from-external-scripts) moved to the separate package for preventing problems with dependencies
- changed `$` prefix for internal modules file names because Team Foundation Server does not support it, [#129](https://github.com/zloirock/core-js/issues/129)
- additional fix for `SameValueZero` in V8 ~ Chromium 39-42 collections
- additional fix for FF27 `Array` iterator
- removed usage shortcuts for `arguments` object - old WebKit bug, [#150](https://github.com/zloirock/core-js/issues/150)
- `{Map, Set}#forEach` non-generic, [#144](https://github.com/zloirock/core-js/issues/144)
- many other improvements
