* Replaced the deprecated `nd_item::barrier()` member calls in the `accumulators` and `gemm` kernels with the SYCL 2020 `sycl::group_barrier()` free function [#3006](https://github.com/IntelPython/dpnp/pull/3006)
* Changed `dpnp.broadcast_arrays` and `dpnp.tensor.broadcast_arrays` to return a tuple instead of a list, aligning with the 2025.12 Python array API spec [#2944](https://github.com/IntelPython/dpnp/pull/2944)
* Bumped the default minimum required DPC++ compiler version to `2026.1.1` and migrated to the OpenCL ICD loader from the conda-forge `ocl-icd-system` (Linux) and `khronos-opencl-icd-loader` (Windows) packages [#2905](https://github.com/IntelPython/dpnp/pull/2905)
* Linked the `dpnp_backend_c` library against only the MKL SYCL domains it uses (`BLAS`, `RNG`, `VM`) [#3012](https://github.com/IntelPython/dpnp/pull/3012)
