+Use 64-bit integer size on 64-bit platforms in fallback lapack_lite
+-------------------------------------------------------------------
+
+Use 64-bit integer size on 64-bit platforms in the fallback LAPACK library,
+which is used when the system has no LAPACK installed, allowing it to deal with
+linear algebra for large arrays.

+Removed ``multiarray.int_asbuffer``
+-----------------------------------
+
+As part of the continued removal of Python 2 compatibility,
+``multiarray.int_asbuffer`` was removed. On Python 3, it threw a
+``NotImplementedError`` and was unused internally. It is expected that there
+are no downstream use cases for this method with Python 3.

+Better support for ``const`` dimensions in API functions
+--------------------------------------------------------
+The following functions now accept a constant array of ``npy_intp``:
+
+* `PyArray_BroadcastToShape`
+* `PyArray_IntTupleFromIntp`
+* `PyArray_OverflowMultiplyList`
+
+Previously the caller would have to cast away the const-ness to call these
+functions.
