 Changelog
 ======
 
+v1.31 (2012-05-02) - Easier to use callbacks (+ optional "active" class for the next/prev buttons when animating slides. If you need this functionality, open the unminified version and search for "Adds active class during slide animation" and remove comments around it).
+
 v1.3 (2012-04-26) - Three new options: "random", "pause", "pauseControls" + small bug fixes.
 
 v1.25 (2012-04-19) - No more flashing of unstyled slideshow before JS has loaded. Adds also better support for cases when JavaScript isn't available.
