 #### NOTE: To upgrade to jQuery 3.0, you first need version 1.12.x or 2.2.x. If you're using an older version, first upgrade to one of these versions using [jQuery Migrate 1.x](https://github.com/jquery/jquery-migrate/tree/1.x-stable#readme), to resolve any compatibility issues. For more information about the changes made in jQuery 3.0, see the [upgrade guide](https://jquery.com/upgrade-guide/3.0/) and [blog post](https://blog.jquery.com/2016/06/09/jquery-3-0-final-released/).

 The development version of the plugin displays warnings in the browser console. Older browsers such as IE9 doesn't support the console interface. No messages will be generated unless you include a debugging library such as [Firebug Lite](https://getfirebug.com/firebuglite) before including the jQuery Migrate plugin. Developers can also inspect the `jQuery.migrateWarnings` array to see what error messages have been generated.
