Oct 1, 2024October 2024 monthly summary for langchain-ai/delta-rs: Focused on stabilizing release readiness and preserving backward compatibility by rolling back deprecated S3 key configuration changes. Implemented a targeted rollback of the S3 key config deprecation, removing the newly added constants for assume role ARN and role session name and eliminating corresponding environment variable settings in the test setup to align with deprecated keys. Ensured test suites reflect the rollback and maintain codebase stability without introducing breaking changes for users.
