The first SmartMenus jQuery update is now available as we release v0.9.2. There is an important fix in "sm-core-css.css" for an issue in Chrome which could prevent the page scroll bar(s) from appearing even if the page is big enough to require scrolling. It also includes some fixes for the mouse/touch input detection code for the upcoming IE 11 which features updated Pointer Events support. So it's a recommended update for all users.
Apart from the code tweaks, a new theme is now also available. Named "sm-clean" it's basically a simple clean looking theme that features visual carets for the horizontal main menu popups.
