+
+The IDNA codec decoder used on DNS hostnames by :mod:`socket` or
+:mod:`asyncio` related name resolution functions no longer involves a
+quadratic algorithm. This prevents a potential CPU denial of service if an
+out-of-spec excessive length hostname involving bidirectional characters
+were decoded. Some protocols such as :mod:`urllib` http ``3xx`` redirects
+potentially allow for an attacker to supply such a name.
+
+Individual labels within an IDNA encoded DNS name will now raise an error
+early during IDNA decoding if they are longer than 1024 unicode characters
+given that each decoded DNS label must be 63 or fewer characters and the
+entire decoded DNS name is limited to 255. Only an application presenting a
+hostname or label consisting primarily of :rfc:`3454` section 3.1 "Nothing"
+characters to be removed would run into of this new limit. See also
+:rfc:`5894` section 6 and :rfc:`3491`.

+The docs clearly say that ``PyImport_Inittab``,
+:c:func:`PyImport_AppendInittab`, and :c:func:`PyImport_ExtendInittab`
+should not be used after :c:func:`Py_Initialize` has been called. We now
+enforce this for the two functions.  Additionally, the runtime now uses an
+internal copy of ``PyImport_Inittab``, to guard against modification.

+
+When calling into Python code from C code, through
+:c:func:`PyEval_EvalFrameEx` or a related C-API function, a shim frame in
+inserted into the call stack. This occurs in the
+``_PyEval_EvalFrameDefault()`` function. The extra frame should be invisible
+to all Python and most C extensions, but out-of-process profilers and
+debuggers need to be aware of it. These shim frames can be detected by
+checking ``frame->owner == FRAME_OWNED_BY_CSTACK``.
+
+Extensions implementing their own interpreters using PEP 523 need to be
+aware of this shim frame and the changes to the semantics of
+:opcode:`RETURN_VALUE`, :opcode:`YIELD_VALUE`, and
+:opcode:`RETURN_GENERATOR`, which now clear the frame.

+Some configurable capabilities of sub-interpreters have changed. They always
+allow subprocesses (:mod:`subprocess`) now, whereas before subprocesses
+could be optionally disaallowed for a sub-interpreter. Instead
+:func:`os.exec` can now be disallowed. Disallowing daemon threads is now
+supported.  Disallowing all threads is still allowed, but is never done by
+default. Note that the optional restrictions are only available through
+``_Py_NewInterpreterFromConfig()``, which isn't a public API. They do not
+affect the main interpreter, nor :c:func:`Py_NewInterpreter`.
