[WIP] 1.0

[zloirock]

• Add Observable if it will be enough stable Awaiting results of the July TC39 meeting - will be discussed Observable API.
• Add logic for well-known symbols if it will be enough fast:
  • Symbol.match
  • Symbol.replace
  • Symbol.split
  • Symbol.search
• Actualize and optimize work with iterables:
  • Optimize Map, Set, WeakMap, WeakSet constructors, Promise.all, Promise.race for default Array Iterator.
  • Optimize Array.from for default Array Iterator.
  • Add core.getIteratorMethod helper.
• Use enumerable properties in shimmed instances - collections, iterators, etc for optimize performance.
• Add support native constructors to Reflect.construct with 2 arguments.
• Add support native constructors to Function#bind shim with new.
• Remove obsolete .clear methods native Weak-collections.
• Final cleaning non-standard features:
  • Move $for to separate library. This work for syntax - for-of loop and comprehensions.
  • Move Date#{format, formatUTC} to separate library. Standard way for this - ECMA-402.
  • Remove Math methods from Number.prototype. Slight sugar for simple Math methods calling.
  • Remove {Array#, Array, Dict}.turn.
  • Remove core.global.
• Use ToNumber instead of ToLength in Number Iterator, Array.from(2.5) will be [0, 1, 2] instead of [0, 1].
• Maximum modularity, split to submodules:
  • es6.reflect
  • es6.regexp
  • es6.math
  • es6.number
  • es7.object.to-array
  • core.object
  • core.string
  • core.iter-helpers
  • Internal modules ($, $.iter, etc)
• Fix Nested setTimeout calls cause invalid Promise unhandled rejection message #85 - invalid Promise unhandled rejection message in nested setTimeout.
• Fix Unable to execute core-js in firefox's content_script environment #86 - support FF extensions.
• Fix Number constructor issue #89 - behavior Number constructor in strange case.
• Add to README "missing polyfills" section.
• Refactoring.

Something else?

[Awk34]

"Refactoring" is pretty broad... Are you referencing a specific refactoring task(s)?

[zloirock]

@Awk34 "refactoring" here isn't something concrete - is a task for me inspect all library code and rewrite all required before release. If you have concrete ideas for next release - you can propose them here.

[andreypopp]

Probably https://github.com/whatwg/fetch but maybe I misunderstand the scope of core-js?

[zloirock]

@andreypopp already opened #25. Possible, but not in this release.
