Sep 1, 2025September 2025 monthly summary for intel/compute-runtime focused on codebase maintenance that enables safer future changes and reduces build friction. Delivered a targeted codebase refactor to improve header organization: moved blit_properties_ext.h into a definitions subfolder and updated CMake include paths to reflect the new structure. This reduces navigation friction, mitigates header collision risks, and lays groundwork for safer, larger-scale refactors across the repository.
