It would be nice if you would add a notice into the commit info that the "emblem_woe_change" option is not featured anymore and that the new option to use the option "disable_change_emblem" instead.
Otherwise you could parse it for backward compatability and store the value(yes/no) according to the bitmask(which would be 1=during WoE) into the new option field.
