Core and builtins ----------------- +- Made omitted callback and None equivalent for weakref.ref() and + weakref.proxy(); the None case wasn't handled correctly in all + cases. + +- Fixed problem where PyWeakref_NewRef() and PyWeakref_NewProxy() + assumed that initial existing entries in an object's weakref list + would not be removed while allocating a new weakref object. Since + GC could be invoked at that time, however, that assumption was + invalid. In a truly obscure case of GC being triggered during + creation for a new weakref object for an referent which already + has a weakref without a callback which is only referenced from + cyclic trash, a memory error can occur. This consistently created a + segfault in a debug build, but provided less predictable behavior in + a release build. + - input() builtin function now respects compiler flags such as __future__ statements.
