Where can I find changelog of JavaScript?

Question

I would like to see list of changes that were made in every version of JavaScript. I would also be interested in what is planned to be added in JavaScript and when a new realease is planned.

Do you know any site where this info can be found?

Thank you

It would be cool to see an exact revision/feature history. Like, did for() come before, after or along with while() – Sucrase

1. The standard it is based around: Ecmascript specs: http://www.ecma-international.org/publications/standards/Ecma-262.htm

2. Firefox specifics: MDC javascript docs including differences in javascript versions: https://developer.mozilla.org/en/javascript

3. IE specifics: MSDN library, scripting area: http://msdn.microsoft.com/en-us/library/ff729665(v=VS.94).aspx

The only comparison/changelog you should care about are the differences between ES3 & ES5. Also can you find any information/changelogs for chrome/safari/opera ? – Food

Where are the differences between the versions? – Supraliminal

JavaScript is a dialect of ECMAScript, have a look at the Wikipedia page of ECMAScript for a version history. You can find the full documentation on the official ECMAScript page.
