Core and Builtins
-----------------
-- Issue #16345: Fix an infinite loop when ``fromkeys`` on a dict subclass
- received a nonempty dict from the constructor.
-
-- Issue #16197: Update winreg docstrings and documentation to match code.
- Patch by Zachary Ware.
-
-- Issue #14700: Fix buggy overflow checks when handling large precisions and

+ Py_TPFLAGS_TYPE_SUBCLASS ((1 << 31). PyType_GetFlags() result type is
+ now unsigned too (unsigned long, instead of long).

- created using PyType_FromSpec().
+- Fix segfaults on setting __qualname__ on builtin types and attempting to
+ delete it on any type.

- the module name that was not interned.
+- Issue #15965: Explicitly cast `AT_FDCWD` as (int). Required on Solaris 10

- allocating path buffers on the heap instead of the stack.

+ Patch by Felipe Cruz.

+ subscriptable.
