Nanowbind

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

* PyPy 7.3.10 or newer is now supported subject to `certain limitations
<https://github.com/wjakob/nanobind/blob/master/docs/pypy.rst>`__. (commits
`f935f93
<https://github.com/wjakob/nanobind/commit/f935f93b9d532a5ef1f385445f328d61eb2af97f>`__
and `b343bbd
<https://github.com/wjakob/nanobind/commit/b343bbd11c12b55bbc00492445c743cae18b298f>`__).
* Three changes that reduce the binary size and improve runtime performance of
binding libraries. (commits `07b4e1fc
<https://github.com/wjakob/nanobind/commit/07b4e1fc9e94eeaf5e9c2f4a63bdb275a25c82c6>`__,

<https://github.com/wjakob/nanobind/commit/9a803796cb05824f9df7593edb984130d20d3755>`__,
and `cba4d285
<https://github.com/wjakob/nanobind/commit/cba4d285f4e23b888dfcccc656c221414138a2b7>`__).
* Fixed a reference leak in ``python_error::what()`` (commit `61393ad
<https://github.com/wjakob/nanobind/commit/61393ad3ce3bc68d195a1496422df43d5fb45ec0>`__).
* Adopted a new policy for function type annotations. (commit `c855c90 <https://github.com/wjakob/nanobind/commit/c855c90fc91d180f7c904c612766af6a84c017e3>`__).
* Improved the effectiveness of link-time-optimization when building extension modules
with the ``NB_STATIC`` flag. This leads to smaller binaries. (commit `f64d2b9
<https://github.com/wjakob/nanobind/commit/f64d2b9bb558afe28cf6909e4fa47ebf720f62b3>`__).
* Nanobind now relies on standard mechanisms to inherit the ``tp_traverse`` and
``tp_clear`` type slots instead of trying to reimplement the underlying
CPython logic (commit `efa09a6b
<https://github.com/wjakob/nanobind/commit/efa09a6bf6ac27f790b2c96389c2da42d4bc176b>`__).
* Moved nanobind internal data structures from ``builtins`` to Python
interpreter state dictionary. (issue `96
<https://github.com/wjakob/nanobind/issues/96>`__, commit `ca23da7
<https://github.com/wjakob/nanobind/commit/ca23da72ce71a45318f1e59474c9c2906fce5154>`__).
* Various minor fixes and improvements.

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

* Caster for untyped ``void *`` pointers. (commit `6455fff

``nb::class_<T>::def_readwrite_static()`` (PR `94
<https://github.com/wjakob/nanobind/pull/94>`__).

traversal through inter-language callbacks (PR `95
<https://github.com/wjakob/nanobind/pull/95>`__).

construction. (commit `38ba18a
<https://github.com/wjakob/nanobind/commit/38ba18a835cfcd561efb4b4c640ee5c6d525decb>`__).

Python's cyclic garbage collector. (commit `662e1b9
<https://github.com/wjakob/nanobind/commit/662e1b9311e693f84c58799a67064d4a44bb706a>`__).
* Added a workaround for spurious reference leak warnings caused by other
extension modules in conjunction with ``typing.py`` (commit `5e11e80
<https://github.com/wjakob/nanobind/commit/5e11e8032f777c0a34abd437dc6e84a909907c91>`__).

`384f4a
<https://github.com/wjakob/nanobind/commit/384f4ada1f3f08486fb03427227878ddbbcaad43>`__).

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

* Fixed undefined behavior that could lead to crashes when nanobind types were
freed. (commit `39266e
<https://github.com/wjakob/nanobind/commit/39266ef0b0ccd7fa3e9237243a6c97ba8db2cd2a>`__).
