This latest release of Xi has a couple of significant enhancements.
Xi’s BuddyPress code is now enabled from an option inside the Theme Options page. You no longer need to edit functions.php to enable BuddyPress support for Xi.
New Show Posts/Pages Shortcode
The ThemeLoom widgets that come with Xi are proving popular among users as they provide a really flexible way to construct content. Well, now we have added a new shortcode to give access to the Show Pages/Posts widget inside any post or page. So now you can create blocks of posts/pages with or without thumbs inside a page or post. Just click the new Visual Editor button to insert the shortcode and see the support pages for details.
These two new features along with a few minor fixes are included in version 1.4 of Xi. You can download the latest version from Your Loom.
