* :c:struct:`PyLongObject` has had its internals changed for better performance.
Although the internals of :c:struct:`PyLongObject` are private, they are used
by some extension modules.
The internal fields should no longer be accessed directly, instead the API
functions beginning ``PyLong_...`` should be used instead.
Two new *unstable* API functions are provided for efficient access to the
value of :c:struct:`PyLongObject`\s which fit into a single machine word:

* :c:func:`PyUnstable_Long_IsCompact`
* :c:func:`PyUnstable_Long_CompactValue`
