The jQuery team continues to provide support for legacy browsers on the compat branch. Use the latest compat release if support for those browsers is required. See [browser support](http://jquery.com/browser-support/) for more info.
 - To use jQuery in Node, browser extensions, and other non-browser environments, use only master branch releases given the name "jquery" rather than "jquery-compat". The compat branch does not support these environments.
