NumPy 2.5.2 Release Notes
=========================

The NumPy 2.5.2 is a patch release that fixes bugs discovered after the 2.5.1
release. The big news is that it includes wheels for the newly released
Python 3.15.0rc1.

This release supports Python versions 3.12-3.15

C API changes
=============

``PyArray_StringDTypeObject`` is opaque under the abi3t stable ABI
------------------------------------------------------------------

The ``PyArray_StringDTypeObject`` was accidentally exposed in NumPy
2.5 when targeting the free-threading-compatible stable ABI
(``Py_TARGET_ABI3T``). ``PyArray_StringDTypeObject`` is now an opaque
struct: extensions compiled that way cannot access its fields, since
the struct layout depends on the size of the object header. Any code
that accessed ``PyArray_StringDTypeObject`` fields in an abi3t build
would have crashed, so we are making this API change in a bugfix
release.

The ``NpyString`` allocator API remains usable by passing the
descriptor object pointer, e.g.
``NpyString_acquire_allocator((PyArray_StringDTypeObject *)descr)``.
