 ## [0.22.0] - Apr. 14, 2026
 
 The highlight of this release is the full migration of `dpctl.tensor` submodule to sister project [`dpnp`](https://github.com/IntelPython/dpnp), shrinking the size of the package tremendously, by between 93% and 96%. The `__sycl_usm_array_interface__` is still supported, with `dpctl` serving as curator of the protocol.
