+ for the integer formats ('bBhHiIlLqQ'). In the following, '*'
+ represents any of '=', '<', '>'.
+
+ - Packing a float now always gives a Deprecation Warning.
+ Previously it only warned for 'I', 'L', '*B', '*H', '*I', '*L'.
+
+ - If x is not an int, long or float, then packing x will always
+ result in struct.error. Previously an x with an __int__ method
+ could be packed by 'b', 'B', 'h', 'H', 'i', 'l', '*b', '*h'
+ ,'*i', '*l', and an x with a __long__ method could be packed by
+ 'q', 'Q', '*q', '*Q'; for x with neither __int__ nor __long__,
+ TypeError used to be raised (with a confusing error message) for
+ 'I', 'L', '*B', '*H', '*I', '*L', and struct.error in other cases.
