curses.color_pair() now raises OverflowError for a pair number too large to be packed, instead of silently masking it to a different pair. The attr argument of the character-cell and attribute methods (addch, addstr, attron, attrset and others) now goes through the checked attr converter, so an out-of-range or non-integer attribute is rejected rather than silently truncated.
