 * Refactored `dpnp.fft` and `dpnp.random` submodules by removing wildcard imports and defining explicit public exports [#2649](https://github.com/IntelPython/dpnp/pull/2649)
 * Added support for the `out` keyword to accept a tuple, bringing ufunc signatures into alignment with those in NumPy [#2664](https://github.com/IntelPython/dpnp/pull/2664)
 * Unified public API definitions in `dpnp.linalg` and `dpnp.scipy` submodules [#2663](https://github.com/IntelPython/dpnp/pull/2663)
+* Aligned the signature of `dpnp.reshape` function with Python array API by making `shape` a required argument [#2673](https://github.com/IntelPython/dpnp/pull/2673)
