Given that 2.7 has now been end-of-life for two and a half years, I don't think we need such a detailed explanation here anymore of the differences between Python 2 and Python 3.

@@ -2502,16 +2502,6 @@ The representation of bytes objects uses the literal format (``b'...'``)
 since it is often more useful than e.g. ``bytes([46, 46, 46])``.  You can
 always convert a bytes object into a list of integers using ``list(b)``.

-   For Python 2.x users: In the Python 2.x series, a variety of implicit
-   conversions between 8-bit strings (the closest thing 2.x offers to a
-   built-in binary data type) and Unicode strings were permitted. This was a
-   backwards compatibility workaround to account for the fact that Python
-   originally only supported 8-bit text, and Unicode text was a later
-   addition. In Python 3.x, those implicit conversions are gone - conversions
-   between 8-bit binary data and Unicode text must be explicit, and bytes and
-   string objects will always compare unequal.
