Jan 1, 2025January 2025 (2025-01) focused on strengthening the Cognite SDK Python’s stability, security, and developer experience. Delivered major dependency upgrades with removal of obsolete backport dependencies for Python ≥3.9, enhancing security and compatibility. Improved the client update experience with a robust version checker, updated to 7.71.1, and refactored update-fetching and comparison logic to reliably notify users of available SDK updates. Expanded datapoints API reliability by adding instance_id support to retrieve_latest and hardening behavior when ignore_unknown_ids is True, preventing KeyError/RuntimeError. Introduced a skip_already_deleted option in ResultSetExpression to control soft-deleted results and updated the version accordingly. Strengthened error handling in update paths to enforce instance_id precedence and clearly report conflicts. Fixed enum value casing in data modeling dumps, updated AI Documents API docs, and improved error handling. Simplified user profile retrieval after AUTH-1293 by removing redundant sorting/casting for consistent ordering. Overall impact: increased security, compatibility, and reliability; clearer upgrade paths for developers; more predictable data queries and API behavior; better documentation and data modeling correctness. Demonstrated skills include Python dependency management, API design enhancements, robust error handling, data modeling, and documentation improvements.
