Describe the issue:

The API for np.reshape was modified to accept all the arguments from the Array API in #26292, but there was a side effect which was not reported in the release notes of v2.1.0.

The issue is that the order argument could previously be passed by position, but now it is keyword-only.

Reproduce the code example:

import numpy as np

np.reshape(np.arange(4), (2, 2), "C")

Error message:

On v2.0.1: nothing, not even a warning

On v2.1.0:
File "/dev/np_reshape.py", line 3, in <module>
    np.reshape(np.arange(4), (2, 2), "C")
TypeError: reshape() takes from 1 to 2 positional arguments but 3 were given

Python and NumPy Versions:

2.1.0
3.12.4 (main, Jun 6 2024, 18:26:44) [GCC 11.4.0]

Runtime Environment:

No response

Context for the issue:

I don't think it's a bad thing to have to specify the order by keyword, but I think in this case the change was not intended as:

• there was no warning in previous version,
• there was nothing in the release notes about this,
• in the stubs, passing order by position is valid, but not at runtime.
