Starting with Neuron 2.28, all NKI Library kernels will migrate to the new ``nki.*`` namespace. The new ``nki.*`` namespace introduces changes to NKI APIs and language constructs that improve usability and performance. This transition ensures consistency across all NKI kernels and allows us to focus development efforts on a single, modern namespace. See :doc:`the NKI Kernel Migration Guide ` for more information.
