+==== Enabling DPU device management with the DPU Operator
+With this release, {product-title} introduces the Data Processing Unit (DPU) Operator, enabling management of DPU devices. The DPU Operator manages components on compute nodes with DPUs, enabling the offloading of data workloads such as networking, storage, and security. This leads to improved cluster performance, reduced latency, and enhanced security, contributing to a more efficient infrastructure. For more information, see xref:../networking/networking_operators/dpu-operator/about-dpu.adoc#about-dpu-and-dpu-operator[About DPU and the DPU Operator].
