1.1.4 - 2015.09.05

• fixed support symbols in FF34-35 Object.assign
• fixed collections iterators in FF25-26
• fixed non-generic WebKit Array.of
• some other fixes and optimizations

1.1.3 - 2015.08.29

• fixed support Node.js domains in Promise, #103

1.1.2 - 2015.08.28

• added toJSON method to Symbol polyfill and to MS Edge implementation for expected JSON.stringify result w/o patching this method
• replaced Reflect.construct implementations w/o correct support third argument
• fixed global detection with changed document.domain in ~IE8, #100

1.1.1 - 2015.08.20

• added more correct microtask implementation for Promise

1.1.0 - 2015.08.17

• updated string padding to actual proposal - renamed, minor internal changes:
  • String#lpad -> String#padLeft
  • String#rpad -> String#padRight
• added string trim functions - proposal, defacto standard - required only for IE11- and fixed for some old engines:
  • String#trimLeft
  • String#trimRight
• String#trim fixed for some engines by es6 spec and moved from es5 to single es6 module
• splitted es6.object.statics-accept-primitives
• caps for freeze-family Object methods moved from es5 to es6 namespace and joined with es6 wrappers
• es5 namespace also includes modules, moved to es6 namespace - you can use it as before
• increased MessageChannel priority in $.task, #95
• does not get global.Symbol on each getting iterator, if you wanna use alternative Symbol shim - add it before core-js
• Reflect.construct optimized and fixed for some cases
• simplified Reflect.enumerate, see this question
• some corrections in Math.acosh
• fixed Math.imul for old WebKit
• some fixes in string / RegExp well-known symbols logic
• some other fixes and optimizations

1.0.1 - 2015.07.31

• some fixes for final MS Edge, replaced broken native Reflect.defineProperty
• some minor fixes and optimizations
• changed compression client/*.min.js options for safe Function#name and Function#length, should be fixed #92

1.0.0 - 2015.07.22

• added logic for well-known symbols:
  • Symbol.match
  • Symbol.replace
  • Symbol.split
  • Symbol.search
• actualized and optimized work with iterables:
  • optimized Map, Set, WeakMap, WeakSet constructors, Promise.all, Promise.race for default Array Iterator.
  • optimized Array.from for default Array Iterator.
  • added core.getIteratorMethod helper.
• uses enumerable properties in shimmed instances - collections, iterators, etc for optimize performance.
• added support native constructors to Reflect.construct with 2 arguments.
• added support native constructors to Function#bind shim with new.
• removed obsolete .clear methods native Weak-collections.
• maximum modularity, reduced minimal custom build size, separated into submodules:
  • es6.reflect
  • es6.regexp
  • es6.math
  • es6.number
  • es7.object.to-array
  • core.object
  • core.string
  • core.iter-helpers
  • internal modules ($, $.iter, etc)
• many other optimizations
• final cleaning non-standard features:
  • moved $for to separate library. This work for syntax - for-of loop and comprehensions.
  • moved Date#{format, formatUTC} to separate library. Standard way for this - ECMA-402.
  • removed Math methods from Number.prototype. Slight sugar for simple Math methods calling.
  • removed {Array#, Array, Dict}.turn.
  • removed core.global.
• uses ToNumber instead of ToLength in Number Iterator, Array.from(2.5) will be [0, 1, 2] instead of [0, 1].
• fixed #85 - invalid Promise unhandled rejection message in nested setTimeout.
• fixed #86 - support FF extensions.
• fixed #89 - behavior Number constructor in strange case.

0.9.18 - 2015.06.17

• removed / from RegExp.escape escaped characters

0.9.17 - 2015.06.14

• updated RegExp.escape to the latest proposal
• fixed conflict with webpack dev server + IE buggy behavior

0.9.16 - 2015.06.11

• more correct order resolving thenable in Promise polyfill
• uses polyfill instead of buggy V8 Promise
