Changes will be summarized here periodically.
Version 2.12.0 (March 27, 2025)
-------------------------------
New Features:
* ``pybind11`` now supports compiling for
`NumPy 2 <https://numpy.org/devdocs/numpy_2_0_migration_guide.html>`_. Most
code shouldn't change (see :ref:`upgrade-guide-2.12` for details). 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 <https://github.com/pybind/pybind11/pull/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 <https://github.com/pybind/pybind11/pull/4877>`_
* Support move-only iterators in ``py::make_iterator``,
``py::make_key_iterator``, ``py::make_value_iterator``.
`#4834 <https://github.com/pybind/pybind11/pull/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 <https://github.com/pybind/pybind11/pull/4772>`_
Bug fixes:
* Removes potential for Undefined Behavior during process teardown.
`#4897 <https://github.com/pybind/pybind11/pull/4897>`_
* Improve compatibility with the nvcc compiler (especially CUDA 12.1/12.2).
`#4893 <https://github.com/pybind/pybind11/pull/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 <https://github.com/pybind/pybind11/pull/4857>`_
* Builtins collections names in docstrings are now consistently rendered in
lowercase (list, set, dict, tuple), in accordance with PEP 585.
`#4833 <https://github.com/pybind/pybind11/pull/4833>`_
* Added ``py::typing::Iterator<T>``, ``py::typing::Iterable<T>``.
`#4832 <https://github.com/pybind/pybind11/pull/4832>`_
* Render ``py::function`` as ``Callable`` in docstring.
`#4829 <https://github.com/pybind/pybind11/pull/4829>`_
* Also bump ``PYBIND11_INTERNALS_VERSION`` for MSVC, which unlocks two new
features without creating additional incompatibilities.
`#4819 <https://github.com/pybind/pybind11/pull/4819>`_
* Guard against crashes/corruptions caused by modules built with different MSVC
versions.
`#4779 <https://github.com/pybind/pybind11/pull/4779>`_
* A long-standing bug in the handling of Python multiple inheritance was fixed.
See PR #4762 for the rather complex details.
`#4762 <https://github.com/pybind/pybind11/pull/4762>`_
* Fix ``bind_map`` with ``using`` declarations.
`#4952 <https://github.com/pybind/pybind11/pull/4952>`_
* Qualify ``py::detail::concat`` usage to avoid ADL selecting one from
somewhere else, such as modernjson's concat.
`#4955 <https://github.com/pybind/pybind11/pull/4955>`_
* Use new PyCode API on Python 3.12+.
`#4916 <https://github.com/pybind/pybind11/pull/4916>`_
* Minor cleanup from warnings reported by Clazy.
`#4988 <https://github.com/pybind/pybind11/pull/4988>`_
* Remove typing and duplicate ``class_`` for ``KeysView``/``ValuesView``/``ItemsView``.
`#4985 <https://github.com/pybind/pybind11/pull/4985>`_
* Use ``PyObject_VisitManagedDict()`` and ``PyObject_ClearManagedDict()`` on Python 3.13 and newer.
`#4973 <https://github.com/pybind/pybind11/pull/4973>`_
* Update ``make_static_property_type()`` to make it compatible with Python 3.13.
`#4971 <https://github.com/pybind/pybind11/pull/4971>`_
.. fix(types)
* Render typed iterators for ``make_iterator``, ``make_key_iterator``,
``make_value_iterator``.
`#4876 <https://github.com/pybind/pybind11/pull/4876>`_
* Add several missing type name specializations.
`#5073 <https://github.com/pybind/pybind11/pull/5073>`_
* Change docstring render for ``py::buffer``, ``py::sequence`` and
``py::handle`` (to ``Buffer``, ``Sequence``, ``Any``).
`#4831 <https://github.com/pybind/pybind11/pull/4831>`_
* Fixed ``base_enum.__str__`` docstring.
`#4827 <https://github.com/pybind/pybind11/pull/4827>`_
* Enforce single line docstring signatures.
`#4735 <https://github.com/pybind/pybind11/pull/4735>`_
* Special 'typed' wrappers now available in ``typing.h`` to annotate tuple, dict,
list, set, and function.
`#4259 <https://github.com/pybind/pybind11/pull/4259>`_
* Create ``handle_type_name`` specialization to type-hint variable length tuples.
`#5051 <https://github.com/pybind/pybind11/pull/5051>`_
.. fix(build)
* Setting ``PYBIND11_FINDPYTHON`` to OFF will force the old FindPythonLibs mechanism to be used.
`#5042 <https://github.com/pybind/pybind11/pull/5042>`_
* Skip empty ``PYBIND11_PYTHON_EXECUTABLE_LAST`` for the first cmake run.
`#4856 <https://github.com/pybind/pybind11/pull/4856>`_
* Fix FindPython mode exports & avoid ``pkg_resources`` if
``importlib.metadata`` available.
`#4941 <https://github.com/pybind/pybind11/pull/4941>`_
* ``Python_ADDITIONAL_VERSIONS`` (classic search) now includes 3.12.
`#4909 <https://github.com/pybind/pybind11/pull/4909>`_
* ``pybind11.pc`` is now relocatable by default as long as install destinations
are not absolute paths.
`#4830 <https://github.com/pybind/pybind11/pull/4830>`_
* Correctly detect CMake FindPython removal when used as a subdirectory.
`#4806 <https://github.com/pybind/pybind11/pull/4806>`_
* Don't require the libs component on CMake 3.18+ when using
PYBIND11_FINDPYTHON (fixes manylinux builds).
`#4805 <https://github.com/pybind/pybind11/pull/4805>`_
* ``pybind11_strip`` is no longer automatically applied when
``CMAKE_BUILD_TYPE`` is unset.
`#4780 <https://github.com/pybind/pybind11/pull/4780>`_
* Support ``DEBUG_POSFIX`` correctly for debug builds.
`#4761 <https://github.com/pybind/pybind11/pull/4761>`_

deprecated APIs and their replacements, build system changes, general code
modernization and other useful information.
.. _upgrade-guide-2.12:
v2.12
=====
NumPy support has been upgraded to support the 2.x series too. The two relevant
changes are that:
* ``dtype.flags()`` is now a ``uint64`` and ``dtype.alignment()`` an
``ssize_t`` (and NumPy may return an larger than integer value for
``itemsize()`` in NumPy 2.x).
* The long deprecated NumPy function ``PyArray_GetArrayParamsFromObject``
function is not available anymore.
Due to NumPy changes, you may experience difficulties updating to NumPy 2.
Please see the [NumPy 2 migration guide](https://numpy.org/devdocs/numpy_2_0_migration_guide.html) for details.
For example, a more direct change could be that the default integer ``"int_"``
(and ``"uint"``) is now ``ssize_t`` and not ``long`` (affects 64bit windows).
If you want to only support NumPy 1.x for now and are having problems due to
the two internal changes listed above, you can define
``PYBIND11_NUMPY_1_ONLY`` to disable the new support for now. Make sure you
define this on all pybind11 compile units, since it could be a source of ODR
violations if used inconsistently. This option will be removed in the future,
so adapting your code is highly recommended.
