There was a problem hiding this comment.
Code changes, LGTM. Would be good to modify the release fragment and rename (we have an expired category).

Create NumPy 1.x and 2.x compatible versions of np.where and np.reshape np.where: When only condition is provided, np.where(condition) is a shorthand for np.asarray(condition).nonzero(). NumPy 2.1.0rc0 disallows 0D input arrays in nonzero, so np.atleast_1d is used here to remain compatible with NumPy 1.x. See numpy/numpy#26268. np.reshape: NumPy 2.1.0rc1 added shape and copy arguments to numpy.reshape. Both newshape and shape keywords are supported (use shape as newshape will be deprecated). Besides, shape cannot be None now. To remain behavior with NumPy 1.x, we now use asarray to create an ndarray. See numpy/numpy#26292. PiperOrigin-RevId: 676587056

…meric` This commit removes deprecated functionality and cleans up outdated code paths: - Removed the deprecated `style` parameter from `array2string` in `numpy/_core/arrayprint.py`, along with its related documentation and tests. - Replaced the deprecation warning for `np.sum` called on generators with a `TypeError` in `numpy/_core/fromnumeric.py`, since this behavior is now unsupported. - Removed a leftover docstring that was intended to be deleted in PR numpy#26268.
