WordPress 3.8.1 has been released. This is a maintenance releases that fixes 31 bugs found in WordPress 3.8.
Various fixes and improvements for the new dashboard design and new themes admin screen. An issue with taxonomy queries in WP_Query was resolved. And if you’ve been frustrated by submit buttons that won’t do anything when you click on them (or thought you were going crazy, like some of us), we’ve found and fixed this “dead zone” on submit buttons.
It also contains a fix for embedding tweets (by placing the URL to the tweet on its own line), which was broken due to a recent Twitter API change.
