 * Changed `dpnp.atleast_1d`, `dpnp.atleast_2d`, `dpnp.atleast_3d`, and `dpnp.ogrid` to return a tuple of arrays instead of a list [#2965](https://github.com/IntelPython/dpnp/pull/2965)
 * Improved performance of `dpnp.fft` functions for complex strided input by avoiding oversized allocations and extra copies [#2939](https://github.com/IntelPython/dpnp/pull/2939)
 * Refreshed `dpnp` documentation styling with the Furo theme [#2934](https://github.com/IntelPython/dpnp/pull/2934)
