During March 2026, Michael Trossbach focused on improving RFC3986 compliance for Airflow connection types in the apache/airflow repository. He addressed a bug where underscores in connection type identifiers caused non-compliance, implementing logic to normalize and validate these identifiers according to RFC3986 standards. Michael enhanced the warning system to check pre-normalized connection types and coalesce missing values, ensuring robust handling of both URI and non-URI connections. His work included expanding unit test coverage and making minor refactors to support static analysis. The project relied on Python for back end development and unit testing, demonstrating careful attention to standards compliance.
