jQuery 1.8.1 has compatibility workaround for custom pseudo-selectors
The developers also advise users not to use Quirks mode because "jQuery has never supported Quirks mode and we do not perform any testing in Quirks". Doing so can affect values such as
$("window").height(). Furthermore, they recommend that users use the new version with jQuery UI 1.8.23 and jQuery Mobile 1.1.1 or later for the best compatibility. The announcement blog post contains a full list of fixes and changes in the update.
Version 1.8.1 of jQuery can be downloaded from the jQuery CDN (Code Delivery Network) as an uncompressed debug build or as a compressed and minimised version for production use; source code is available from the project's GitHub repository. jQuery is dual-licensed under the MIT Licence and the GPLv2.
