Hi we are upgrading jquery cookie from an early alpha version of 1.1 to 1.2. Please start upgrading your code to be compatible with jquery cookie 1.2. There is just one deprecations to notice and that is $.cookie('foo', null) is now deprecated. And replace it with Adding $.removeCookie('foo') for deleting a cookie. We are slowly upgrading to version 1.4.1 but one step at a time because it is. And please also follow this change log github.com/carhartl/jquery-cookie/blob/master/CHANGELOG.md so that we can upgrade to 1.4.1.
