Let's add more details:
Suggested change
| * Using the `.T` property on non-2D `dpnp.ndarray` is deprecated. Use `self.transpose()` or `self.mT` instead [#2681](https://github.com/IntelPython/dpnp/pull/2681) | |
| * `dpnp.ndarray.T` property is deprecated for not two-dimensional array to be compatible with the Python array API standard. To achieve a similar behavior when ``a.ndim != 2``, either ``a.transpose()``, or ``a.mT`` (swaps the last two axes only), or ``dpnp.permute_dims(a, range(a.ndim)[::-1])`` can be used.
