Arash Barghi upgraded the libcuvs dependency from version 25.12 to 26.2 across all environment configuration files in the rapidsai/cugraph repository, focusing on improving compatibility with the latest libraries and reducing build drift. He applied careful dependency management and version pinning using YAML, ensuring the upgrade was harmonized across all relevant files for consistent build and runtime stability. By documenting the change in a single, traceable commit, Arash enabled straightforward auditing and rollback if needed. This work laid the foundation for future updates, addressed potential incompatibilities, and streamlined the build process for graph analytics workloads without introducing new bugs.
