 ## NVIDIA NeMo Curator 1.0.0
 
 This major release represents a fundamental architecture shift from [Dask](https://www.dask.org/) to [Ray](https://www.ray.io/), expanding NeMo Curator to support multimodal data curation with new [video](https://docs.nvidia.com/nemo/curator/latest/curate-video/index.html) and [audio](https://docs.nvidia.com/nemo/curator/latest/curate-audio/index.html) capabilities. This refactor enables unified backend processing, better heterogeneous computing support, and enhanced autoscaling for dynamic workloads.
