July 2025 performance summary for SUNET/puppet-sunet. Focused on cross-database compatibility and code quality, delivering stability improvements while maintaining forward momentum for MariaDB environments. Implemented a MariaDB compatibility workaround by disabling SQLAlchemy RETURNING across supported MariaDB/MySQL configurations, followed by a series of stability-driven reversions to revert that workaround when the baseline was validated. Completed targeted code cleanup, reduced API surface noise by removing unused parameters, and fixed typos in UI and documentation. Business impact includes reduced deployment risk in MariaDB environments, clearer API behavior, and improved developer and user experience through cleaner code and text. Key themes: reliability, cross-database compatibility, and maintainability.
