Also -// added the <jQuery.param.fragment.noEscape> method, and reworked the -// <hashchange event (BBQ)> 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 <jQuery hashchange event> 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 <hashchange event> -// 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 <jQuery hashchange event> -// plugin for more information. Also added the <jQuery.bbq.removeState> -// method and added additional <jQuery.deparam> 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 <jQuery.param.querystring> and <jQuery.param.fragment> -// 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.
