UILocalize's UpdateText gone?

[ENAY]

On some old code, I was changing the text of a Label by changing its keycode.
eg

Prologue_Text_Slider.GetComponentInChildren<UILocalize>().key = key_name;

However the text did not actually update until I called this:-

Prologue_Text_Slider.GetComponentInChildren<UILocalize>().UpdateText(key_name);

Unfortunately after updating NGUI, this UpdateText function is now gone, deleting this line means now the text no longer changes. Has this function been changed to something else?

UILocalize.Localize().
