-- Issue #16197: Update winreg docstrings and documentation to match code.
+- Issue #16086: PyTypeObject.tp_flags and PyType_Spec.flags are now unsigned
+ (unsigned long and unsigned int) to avoid an undefined behaviour with
+ Py_TPFLAGS_TYPE_SUBCLASS ((1 << 31). PyType_GetFlags() result type is
+ now unsigned too (unsigned long, instead of long).
+
+ - Fix segfaults on setting __qualname__ on builtin types and attempting to
+ delete it on any type.
+
+- Issue #14625: Rewrite the UTF-32 decoder. It is now 3x to 4x faster. Patch
+ written by Serhiy Storchaka.
+
+ - Issue #16271: Fix strange bugs that resulted from __qualname__ appearing in a
+ class's __dict__ and on type.
