- update to 2.12.0:
  * pybind11 now supports compiling for NumPy 2.
    However, if you experience issues you can define
    PYBIND11_NUMPY_1_ONLY to disable the new support for now, but
    this will be removed in the future. #5050
  * pybind11/gil_safe_call_once.h was added (it needs to be
    included explicitly). The primary use case is GIL-safe
    initialization of C++ static variables. #4877
  * Support move-only iterators in py::make_iterator,
    py::make_key_iterator, py::make_value_iterator. #4834
  * Two simple py::set_error() functions were added and the
    documentation was updated accordingly. In particular,
    py::exception<>::operator() was deprecated (use one of the
    new functions instead). The documentation for py::exception<>
    was further updated to not suggest code that may result in
    undefined behavior. #4772
  * Removes potential for Undefined Behavior during process
    teardown. #4897
  * Improve compatibility with the nvcc compiler (especially CUDA
    12.1/12.2). #4893
  * pybind11/numpy.h now imports NumPy's multiarray and _internal
    submodules with paths depending on the installed version of
    NumPy (for compatibility with NumPy 2). #4857
  * Builtins collections names in docstrings are now consistently
    rendered in lowercase (list, set, dict, tuple), in accordance
    with PEP 585. #4833
  * Added py::typing::Iterator<T>, py::typing::Iterable<T>. #4832
  * Render py::function as Callable in docstring. #4829
  * Also bump PYBIND11_INTERNALS_VERSION for MSVC, which unlocks
    two new features without creating additional

- update to 2.10.4:
  * ``python3 -m pybind11`` gained a ``--version`` option (prints
    the version and exits).
  * Fix a warning when pydebug is enabled on Python 3.11.
  * Ensure ``gil_scoped_release`` RAII is non-copyable.
  * Ensure the tests dir does not show up with new versions of
    setuptools.
  * Better stacklevel for a warning in setuptools helpers.

- update to 2.9.2:
  * Enum now has an ``__index__`` method on Python <3.8 too.
  * Local internals are now cleared after finalizing the interpreter.
  * Better support for Python 3.11 alphas.
  * ``PYBIND11_TYPE_CASTER`` now uses fully qualified symbols, so it can be used
    outside of ``pybind11::detail``.
  * Some fixes for PyPy 3.9.
  * Fixed a potential memleak in PyPy in ``get_type_override``.
  * Fix usage of ``VISIBILITY_INLINES_HIDDEN``.
  * Uses ``sysconfig`` module to determine installation locations on Python >=
    3.10, instead of ``distutils`` which has been deprecated.
  * Support Catch 2.13.5+ (supporting GLIBC 2.34+).
  * Fix test failures with numpy 1.22 by ignoring whitespace when comparing
    ``str()`` of dtypes.

- update to 2.9.1:
  * If possible, attach Python exception with py::raise_from to TypeError when
    casting from C++ to Python. This will give additional info if Python
    exceptions occur in the caster.
  * Add a mapping of C++11 nested exceptions to their Python exception
    equivalent using py::raise_from. This attaches the nested exceptions in
    Python using the __cause__ field. 
  * Propagate Python exception traceback using raise_from if a pybind11
    function runs out of overloads.
  * py::multiple_inheritance is now only needed when C++ bases are hidden from
    pybind11.
  * Allow py::args to be followed by other arguments; the remaining arguments
    are implicitly keyword-only, as if a py::kw_only{} annotation had been
    used.
  * Fix a rare warning about extra copy in an Eigen constructor.
  * Fix caching of the C++ overrides.
  * Add missing std::forward calls to some cpp_function overloads.
  * Support PyPy 7.3.7 and the PyPy3.8 beta. Test python-3.11 on PRs with the python dev label.
  * Replace usage of deprecated Eigen::MappedSparseMatrix with Eigen::Map<Eigen::SparseMatrix<...>> for Eigen 3.3+.
  * Tweaks to support Microsoft Visual Studio 2022.

- udpate to 2.8.1:
  * The simple namespace creation shortcut added in 2.8.0 was deprecated due to
    usage of CPython internal API, and will be removed soon.
  * Add C++ Exception type to throw and catch ``AttributeError``.
  * Fixed the potential for dangling references when using properties with
  ``std::optional`` types.
  * Modernize usage of ``PyCodeObject`` on Python 3.9+ (moving toward support for
    Python 3.11a1)
  * A long-standing bug in ``eigen.h`` was fixed (originally PR #3343). The bug
    was unmasked by newly added ``static_assert``'s in the Eigen 3.4.0 release.
  * Support multiple raw inclusion of CMake helper files
  * Fix harmless warning on upcoming CMake 3.22.
  * Fix 2.8.0 regression with MSVC 2017 + C++17 mode + Python 3.
  * Fix 2.8.0 regression that caused undefined behavior (typically
    segfaults) in ``make_key_iterator``/``make_value_iterator`` if dereferencing
    the iterator returned a temporary value instead of a reference.
