2.1.0 - 2016.02.09
-
API:
- ES5 polyfills are split and logic, used in other polyfills, moved to internal modules
- All entry point works in ES3 environment like IE8- without
core-js/(library/)es5
- Added all missed single entry points for ES5 polyfills
- Separated ES5 polyfills moved to the ES6 namespace. Why?
- Mainly, for prevent duplication features in different namespaces - logic of most required ES5 polyfills changed in ES6+:
- Already added changes for:
Object
statics - should accept primitives, new whitespaces lists inString#trim
,parse(Int|float)
,RegExp#toString
logic,String#split
, etc - Should be changed in the future:
@@species
andToLength
logic inArray
methods,Date
parsing,Function#bind
, etc - Should not be changed only several features like
Array.isArray
andDate.now
- Some ES5 polyfills required for modern engines
- All old entry points should work fine, but in the next major release API can be changed
-
Object.getOwnPropertyDescriptors
moved to the stage 3, January TC39 meeting - Added
umd
option for custom build process, #169 - Returned entry points for
Array
statics, removed in2.0

subclassing bug causes unhandled rejection on feature detection, #159 - Added fix for very specific environments with global
window === null
2.0.2 - 2016.01.04
- Temporarily removed
length
validation fromUint8Array
constructor wrapper. Reason - bug inws
module (->socket.io
) which passes toBuffer
constructor ->Uint8Array
float and uses theV8
bug for conversion to int (by the spec should be thrown an error). It creates problems for many people. I hope, it will be returned after fixing this bug inV8
