Base64 decoder (see binascii.a2b_base64(), base64.b64decode(), etc)
no longer ignores excess data after the first padded quad in non-strict
(default) mode. Instead, in conformance with RFC 4648, it ignores the
pad character, "=", if it is present before the end of the encoded data.
Add base32 encoder and decoder functions implemented in
C to the binascii module and use them to greatly improve the
performance and reduce the memory usage of the existing
base32 codec functions in the base64 module.
* Add the alphabet parameter in functions b2a_base64(), a2b_base64(),
b2a_base85(), and a2b_base85().
* And a number of "*_ALPHABET" constants.
* Remove b2a_z85() and a2b_z85().
Fix also error handling in _BINARY_OP_ADD_FLOAT,
_BINARY_OP_SUBTRACT_FLOAT and _BINARY_OP_MULTIPLY_FLOAT opcodes.
PyStackRef_FromPyObjectSteal() must not be called with a NULL
pointer.
The DIALECT_GETATTR macro in dialect_new() unconditionally called
PyErr_Clear() when PyObject_GetAttrString() failed, which suppressed
all exceptions including MemoryError, KeyboardInterrupt, and
RuntimeError. Now only AttributeError is cleared; other exceptions
propagate via the existing error handling path.

* Add the c_init_default attribute which is used to initialize the C variable
if the default is not explicitly provided.
* Add the c_default_init() method which is used to derive c_default from
default if c_default is not explicitly provided.
* Explicit c_default and py_default are now almost always have precedence
over the generated value.
* Add support for bytes literals as default values.
* Improve support for str literals as default values (support non-ASCII
and non-printable characters and special characters like backslash or quotes).
* Fix support for str and bytes literals containing trigraphs, "/*" and "*/".
* Improve support for default values in converters "char" and "int(accept={str})".
* Converter "int(accept={str})" now requires 1-character string instead of
integer as default value.
* Add support for non-None default values in converter "Py_buffer": NULL,
str and bytes literals.
* Improve error handling for invalid default values.
* Rename Null to NullType for consistency.
* calling it with non-ASCII string format will now raise a ValueError
instead of UnicodeEncodeError
* calling it with non-ASCII bytes format will now raise a ValueError
instead of struct.error
* getting the format attribute of uninitialized object will now raise
an AttributeError instead of RuntimeError.
* Convert DEOPT_IFs to EXIT_IFs for guards. Keep DEOPT_IF for intentional drops to the interpreter.
* Modify BINARY_OP_SUBSCR_LIST_INT and STORE_SUBSCR_LIST_INT to handle negative indices, to keep EXIT_IFs and DEOPT_IFs in different uops
* Struct.__new__() will require a mandatory argument (format)
* Calls of __init__() method with a different format argument on initialized
Struct are deprecated
