 ## [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.
 
-
 Additionally, `dpctl` build scripts were updated, removing use of `python setup.py develop` and `python setup.py install`, and `dpctl` [documentation page](https://intelpython.github.io/dpctl/latest/index.html) now supports a version dropdown.
 
 **NOTE**: Changes below which reference `tensor` were added to the `tensor` submodule prior to release, and therefore are included in the migrated `tensor` submodule in [`dpnp`](https://github.com/IntelPython/dpnp). They are included here for transparency and continuity of the submodule's history in the changelog.
