-NEP 49 configurable allocators
-------------------------------
-As detailed in `NEP 49`_, the function used for allocation of the data segment
-of a ndarray can be changed. The policy can be set globally or in a context.
-For more information see the NEP and the :ref:`data_memory` reference docs.
-Also add a ``NUMPY_WARN_IF_NO_MEM_POLICY`` override to warn on dangerous use
-of transfering ownership by setting ``NPY_ARRAY_OWNDATA``.

-Implementation of the NEP 47 (adopting the array API standard)
---------------------------------------------------------------
-
-An initial implementation of `NEP 47`_ (adoption the array API standard) has
-been added as ``numpy.array_api``. The implementation is experimental and will
-issue a UserWarning on import, as the `array API standard
-<https://data-apis.org/array-api/latest/index.html>`_ is still in draft state.
-``numpy.array_api`` is a conforming implementation of the array API standard,
-which is also minimal, meaning that only those functions and behaviors that
-are required by the standard are implemented (see the NEP for more info).
-Libraries wishing to make use of the array API standard are encouraged to use
-``numpy.array_api`` to check that they are only using functionality that is
-guaranteed to be present in standard conforming implementations.

-Assign the platform-specific ``c_intp`` precision via a mypy plugin

-directly from the corresponding `~numpy.finfo` attribute.

-Annotating the main Numpy namespace
---------------------------------------
-Starting from the 1.20 release, PEP 484 type annotations have been included
-for parts of the NumPy library; annotating the remaining functions being a
-work in progress. With the release of 1.22 this process has been completed for
-the main NumPy namespace, which is now fully annotated.
-
-Besides the main namespace, a limited number of sub-packages contain
-annotations as well. This includes, among others, `numpy.testing`,
-`numpy.linalg` and `numpy.random` (available since 1.21).

-Change in generation of random 32 bit floating point variates
--------------------------------------------------------------
-There was bug in the generation of 32 bit floating point values from
-the uniform distribution that would result in the least significant
-bit of the random variate always being 0.  This has been fixed.
-
-This change affects the variates produced by the `random.Generator`
-methods ``random``, ``standard_normal``, ``standard_exponential``, and
-``standard_gamma``, but only when the dtype is specified as
-``numpy.float32``.
