Make sure that invariants of type versioning are maintained: * Superclasses
|
|
always have their version number assigned before subclasses * The version
|
|
tag is always zero if the tag is not valid. * The version tag is always
|
|
non-zero if the tag is valid.

Strings interned with :func:`sys.intern` are again garbage-collected when no

|
longer used, as per the documentation. Strings interned with the C function
|
|
:c:func:`PyUnicode_InternInPlace` are still immortal. Internals of the
|
|
string interning mechanism have been changed. This may affect performance
|
|
and identities of :class:`str` objects.
