New Features:

• A new self._pybind11_conduit_v1_() method is automatically added to all py::class_-wrapped types, to enable type-safe interoperability between different independent Python/C++ bindings systems, including pybind11 versions with different PYBIND11_INTERNALS_VERSION's. Supported on pybind11 2.11.2, 2.12.1, and 2.13.6+. #5296

Bug fixes:

• Using __cpp_nontype_template_args instead of __cpp_nontype_template_parameter_class. #5330
• Properly translate C++ exception to Python exception when creating Python buffer from wrapped object. #5324

Documentation:

• Adds an answer (FAQ) for "What is a highly conclusive and simple way to find memory leaks?". #5340
