* Fix elm_conform didn't change indicator mode when create.
+2013-03-06 ChunEon Park (Hermet)
+
+ * Add elm_object_item_signal_callback_add(), elm_object_item_signal_callback_del().
+
* Add omit feature to elm_index.
* Add elm_transit_smooth_set(), elm_transit_smooth_get()
* Add edje_object_message_signal_process before edje_object_size_min_restricted_calc.
+ * Add elm_object_item_signal_callback_add(), elm_object_item_signal_callback_del().
Improvements:
