@ -188,6 +188,10 @@ Addresses
As described in :ref:`address_literals`, hex literals of the correct size that pass the checksum
test are of ``address`` type. No other literals can be implicitly converted to the ``address`` type.
Explicit conversions from ``bytes20`` or any integer type to ``address`` result in ``address payable``.
Explicit conversions to ``address`` are allowed only from ``bytes20`` and ``uint160``.
An ``address a`` can be converted to ``address payable`` via ``payable(a)``.
An ``address a`` can be converted explicitly to ``address payable`` via ``payable(a)``.
.. note::
Prior to version 0.8.0, it was possible to explicitly convert from any integer type (of any size, signed or unsigned) to ``address`` or ``address payable``.
Starting with in 0.8.0 only conversion from ``uint160`` is allowed.
