Also +// added the method, and reworked the +// internal "add" method to be compatible with +// changes made to the jQuery 1.4.2 special events API. +// 1.1.1 - (1/22/2010) Integrated v1.1, which fixes an +// obscure IE8 EmulateIE7 meta tag compatibility mode bug. +// 1.1 - (1/9/2010) Broke out the jQuery BBQ event.special +// functionality into a separate plugin for users who want just the +// basic event & back button support, without all the extra awesomeness +// that BBQ provides. This plugin will be included as part of jQuery BBQ, +// but also be available separately. See +// plugin for more information. Also added the +// method and added additional examples. +// 1.0.3 - (12/2/2009) Fixed an issue in IE 6 where location.search and +// location.hash would report incorrectly if the hash contained the ? +// character. Also and +// will no longer parse params out of a URL that doesn't contain ? or #, +// respectively. +// 1.0.2 - (10/10/2009) Fixed an issue in IE 6/7 where the hidden IFRAME caused +// a "This page contains both secure and nonsecure items." warning when +// used on an https:// page. +// 1.0.1 - (10/7/2009) Fixed an issue in IE 8.
