November 2025 (cowprotocol/token-lists): Delivered S3 deployment enhancements for files.cow.fi, improving reliability and automation for public assets. Key changes include the ability to upload the entire public directory to the files.cow.fi service, the option to manually trigger the S3 deployment, and an extended deployment script that deletes old/untracked files during synchronization to maintain bucket parity. Fixed drift by deleting obsolete files in S3. These changes reduce manual maintenance, improve consistency of asset delivery, and enable faster, more reliable refresh of files.
