 ### Removed
 
 * Removed support for arrays of 2-dimensional vectors in `dpnp.cross`, which now requires (arrays of) 3-dimensional vectors and raises `ValueError` otherwise [#2950](https://github.com/IntelPython/dpnp/pull/2950)
+* Removed `dpnp.row_stack` in favor of `dpnp.vstack` [#2956](https://github.com/IntelPython/dpnp/pull/2956)
