May 2025: Standardized checkpoint storage for instadeepai/Mava by removing the 'path' attribute and introducing a 'rel_dir' attribute to specify relative directories for saving/loading checkpoints, centralizing storage locations in the logger configuration. This reduces configuration drift across environments, improves reproducibility, and simplifies deployment/CI pipelines. The work demonstrates strong configuration hygiene, refactoring discipline, and improved lifecycle management of model checkpoints.
