The 24px smileys, which were previously available by download-and-replace only, are now included standard. To use the new 24px smileys, just select the option on the TSE Options page. I also updated the tinyMCE popup so it would automatically keep up-to-date with new smiley additions. A couple of bugs were also fixed in this update.
