What minifier was used to generate the official JQuery "minified" version?

Question

I need to edit the current JQuery library 1.4.x (and completely rename the JQuery "object/function") in a high conflicting environment.

My question is, with what minifier has the official JQuery minified version been generated. Where can I find this minifier? (As I want to use it for minifing my version too).

Thank you! Tim

Answer 1

According to the offical release notes it is the Google Closure Compiler.

UPDATE:

As of jQuery 1.5 they are using UglifyJS (ticket) instead of the Google Closure Compiler.

Answer 2

I believe it is Google Closure: Google Closure minifier online?
