  "message": "Fix memory leak: clear managed dict in pybind11_object_dealloc on Python 3.13+          (#5999)\n\n* fix: clear managed dict in pybind11_object_dealloc on Python 3.13+\n\nOn Python 3.14, PyObject_GC_Del (tp_free) no longer implicitly clears\nthe managed dict of objects with Py_TPFLAGS_MANAGED_DICT. Without an\nexplicit PyObject_ClearManagedDict() call before tp_free(), objects\nstored in the __dict__ of py::dynamic_attr() instances have their\nrefcounts permanently abandoned, causing memory leaks — capsule\ndestructors for numpy arrays (and other objects) never run.\n\nAdds a regression test: stores a py::capsule in the __dict__ of a\nDynamicClass instance and asserts the capsule destructor is called\nwhen the instance is deleted.\n\n* [tests]: mark test_dynamic_attr_dealloc_frees_dict_contents to be strict\u003dFalse xfail on PYPY\n\n* [docs]: clarify Python version comments in pybind11_object_dealloc\n\nDistinguish between when the API is available (3.13+, where\nPyObject_ClearManagedDict was introduced) and when the leak actually\nmanifests (3.14+, where tp_free stopped implicitly clearing the\nmanaged dict).\n\n---------\n\nCo-authored-by: Yury Matveev \u003cyury.matveev@desy.de\u003e",
