javascript - 什么是 ECMAScript Editon 5.1，它有什么用？

Question

我刚刚偶然发现了这个(在浏览 ECMA 网站时):

http://www.ecma-international.org/activities/Languages/Draft%20Standard%20ECMA-262%205.1%20edition.pdf

它说 here 5.1 版将于 2011 年 6 月取代第 5 版。

我的问题是:这个版本 5.1 是什么，为什么要发布它？ (第5版有问题吗？)

编辑:我发现了这个:

ECMAScript 5.1 is a maintenance revision of the ECMAScript 5 specification. It corrects technical and editorial errors and its content is identical to the proposed ISO edition of the ES5 specification. This is intended to be the final draft, subject to approval by TC39 and the completion of the ISO standardization process.

更新:

作为JavaScript Weekly在今天的时事通讯中发布，ECMAScript 5.1 已经获得批准，并且可以在 ECMAScript 的主页上下载:

The ISO edition of the ES5 specification incorporates a number of editorial and technical corrections including those listed in the current ES5 errata.

换句话说，ECMAScript 5.1 是 5.0 的修订版，修正了文档本身的一些错误。正如本文后面提到的:

Keep in mind that this is only a maintenance revision of the ES5 specification. It contains no new language or library features. TC39 is continuing its longer term work on “ECMAScript Harmony” which is intended to be the next version to include any new features.
