---------------

-Changes will be summarized here periodically.
+New features:
+
+* ``pybind11::detail::is_move_constructible`` can now be specialized for cases
+   in which ``std::is_move_constructible`` does not work as needed. This is
+   very similar to the long-established
+   ``pybind11::detail::is_copy_constructible``.
+  `#4631 <https://github.com/pybind/pybind11/pull/4631>`_
+
+* Introduce ``recursive_container_traits``.
+  `#4623 <https://github.com/pybind/pybind11/pull/4623>`_
+
+* ``pybind11/type_caster_pyobject_ptr.h`` was added to support automatic
+  wrapping of APIs that make use of ``PyObject *``. This header needs to
+  included explicitly (i.e. it is not included implicitly
+  with ``pybind/pybind11.h``).
+  `#4601 <https://github.com/pybind/pybind11/pull/4601>`_

+
+* Compatibility with Python 3.12 (alpha). Note that the minimum pybind11

+* With ``PYBIND11_INTERNALS_VERSION 5`` (default for Python 3.12+), MSVC builds
+  use ``std::hash<std::type_index>`` and ``std::equal_to<std::type_index>``
+  instead of string-based type comparisons. This resolves issues when binding
+  types defined in the unnamed namespace.
