Rev30, the December 24, 2014 draft specification for ECMAScript 6 is now available at: 
http://wiki.ecmascript.org/doku.php?id=harmony:specification_drafts#december_24_2014_draft_rev_30 

Change Summary

	• Made it a runtime error to try to create a subclass of a generator function via a class declaration or class expression.
	• Correct bugs in String.prototype.match/replace/search/split in the logic for double dispatching to a RegExp agument
	• Added language in 8.4 making it explicit that ES Jobs always run to completion
	• Class name is in TDZ during extends clause evaluation
	• Added static semantics that correctly validates statement label usage.
	• Array.prototype.concat/push/splice throw TypeError if new length would be 2^53 or greater. (Bug 3409)
	• Defined the Annex B (B.1.3) lexical grammar extensions for recognizing legacy HTML-like comments
	• Added a forbidden extension item that forbids supporting HTML-line comments within modules.
	• Additional early error for super() in non-constructor methods. (Already had an error for new super()).
	• Object.prototype.toString now uses IsArray to when testing for built-in exotic array instances.
	• IsArray abstract operation now longer throws if argument is a revoked proxy. It just returns false.
	• Simplified and corrected early error naming rules for module exports
	• Fixed several left-to-right evaluation order initialization bugs in various declaration forms
	• Resolved bugs: 3476-3445, 3443, 3441-3434, 3430-428, 3425-418, 3416-3411, 3409-3407, 3405-3404, 3396, 3306, 3284,
