January 2026 achievements: Consolidated CUDA 13.0-enabled release pipeline enhancements and wheel publishing for jeejeelee/vllm and red-hat-data-services/vllm-cpu. Implemented PyPI/GitHub release uploads, enabled CUDA 13.0 release image builds, and reorganized CI/CD steps into grouped, maintainable configurations. Fixed wheel upload versioning/exclusion logic to prevent incorrect uploads, improving reliability of PyPI releases. Standardized release workflows across both repos to reduce nightly release friction and improve cross-team collaboration. Result: faster, safer releases with clearer visibility and lower operational risk.
