 # Note: the ChatZilla version and expected locale versions may not always be
 #       the same. For example, if only non-locale changes have been made, the
 #       expected locale version will stay the same. This is to make using
 #       localisations between versions easier.

 ### End of notes ###

 locale.error = You are using ChatZilla %1$S, which requires the locale version %2$S. The currently selected locale, %3$S, is version %4$S, and therefore there may be problems running ChatZilla.\n\nIt is strongly advised that you update or remove the ChatZilla locale in question.
