Bug fixes:

• Fixed TSS key exhaustion in implicitly_convertible() when many implicit conversions are registered across large module sets. #6020

• Fixed heap-buffer-overflow in pythonbuf with undersized buffers by enforcing a minimum buffer size. #6019

• Fixed virtual-inheritance pointer offset crashes when dispatching inherited methods through virtual bases. #6017

• Fixed free(): invalid pointer crashes during interpreter shutdown with py::enum_<> by duplicating late-added def_property_static argument strings. #6015

• Fixed function_record heap-type deallocation to call PyObject_Free() and decref the type. #6010

• Hardened PYBIND11_MODULE_PYINIT and get_internals() against module-initialization crashes. #6018

• Fixed static_pointer_cast build failure with virtual inheritance in holder_caster_foreign_helpers.h. #6014

• Fixed ambiguous factory template specialization that caused compilation failures with nvcc + GCC 14. #6011

• Fixed crash in def_readwrite for non-smart-holder properties of smart-holder classes. #6008

• Fixed memory leak for py::dynamic_attr() objects on Python 3.13+ by clearing managed __dict__ contents during deallocation. #5999

• Fixed binding of noexcept and ref-qualified (&, &&) methods inherited from unregistered base classes. #5992

Internal:

Tests:

CI:
