replaced fix JSON.stringify + Symbol behavior from .toJSON method to wrapping JSON.stringify - little more correct, compat-table/642
fixed typo which broke tasks scheduler in WebWorkers in old FF, #114

added browser Promise rejection hook, #106
added correct IsRegExp logic to String#{includes, startsWith, endsWith} and RegExp constructor, @@match case, example
updated String#leftPad with proposal: string filler truncated from the right side
replaced V8 Object.assign - its properties order not only incorrect, it is non-deterministic and it causes some problems
fixed behavior with deleted in getters properties for Object.{assign,entries, values}, example
fixed Math.sinh with very small numbers in V8 near Chromium 38
some other fixes and optimizations

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

fixed support Node.js domains in Promise, #103

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

added more correct microtask implementation for Promise

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

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

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.

removed / from RegExp.escape escaped characters
