Changes include:
- Several important bug fixes to Function Declaration Instantiation
- Updated RegExp so that subclasses that over-ride exec semantics don’t have to also over-ride match/replace/search
- disallowed a line break between ArrowParameters and the ⇒
- Adjust Array.prototype.reverse and Array.prototype.unshift to eliminate several unnecessary MOP calls that were exposed if the array is a proxy
- Object.assign now accepts multiple source arguments
- arguments object now have an @@iterator own property
- %TypedArray% constructors now processes iterables as an argument.
- Changed length property value of Symbol, Map, Set, WeakSet, WeakMap to 1 to be consistent with most other built-in constructors
- Added Annex B item about var declarations in catch clauses that binding the same name as a catch parameter
- Array.from/typedArray.from now calls filter function with two arguments.
- Eliminated static semantic rules that made the following an early error function({x}){var x} or generator(x) {var x}. A var declaration now can always be the same name as a formal parameter
- Made for (let x in x), etc. a TDZ violation
- further tweaking of super related productions in MemberExpression and NewExpression
- Bug fix in GetBindingValue to make TDZ work. Accessing an uninitialized binding always throws and is not conditional on strict mode.
- Started update of Annex A. Lexical grammar updated
- Resolved bugs: 2729, 2727, 2724-2722, 2714-2713, 2711-2706, 2695-2688, 2685, 2681-2660, 2658-2657, 2655-2654, 2652-2649, 2647-2640, 2638-2637, 2635-2613, 2611, 2608-2607, 2605-2604, 2600, 2573, 2566, 2561, 2558-2557, 2551, 2548-2547, 2537, 2528-2526, 2477, 2445, 2443, 2337, 2314, 2154, 2010, 1540, 1114
