February 2026: Delivered foundational build-system enhancements and compatibility wrappers to strengthen dependency management and Python rule integration across Intel-tensorflow/xla and Intel-tensorflow/tensorflow. Implemented a third-party dependency pathway and added compatibility wrappers for rules_python to support non-standard attributes without modifying source BUILD files, enabling smoother TensorFlow build integration and cross-repo reuse. Refined the build process by adopting wrappers from XLA into TensorFlow to improve compatibility and maintainability across the stack.
