+version 1.3.9 (2012/02/17) ------------------------------------------------------------
+                                                                         Thanks to Gerv
+
+  ENHANCEMENT
+    * Better detection of mobile device in the event cookies are not available.
+
+      If cookies are unavailable AI resorts to basic UA sniffing.
+
+      Previously AI assumed all devices are mobile and searched the UA string for a
+      desktop OS. If found it overrode $mobile_first. However, this meant tablet
+      devices got mobile sized images as their OS is not a desktop OS.
+
+      Now switched to assume the device is a desktop, but AI searches the UA string for
+      'mobile' to switch to mobile first. All current mobile browsers behave in this
+      way, meaning mobiles still get mobile resolution, but tablets and desktop get
+      the largest configured resolution.
+
+    * Removed $mobile_first as it is no longer needed (see above)
