January 2026 highlights: strengthened reliability and maintainability across two repositories. In apache/datafusion-sandbox, fixed epoch calculation for interval types (extract(epoch)) to return total seconds, with regression tests added (date_part.slt) to ensure long-term correctness. In apache/auron, performed Rust code quality cleanup addressing Clippy format and string lint issues to improve readability without changing behavior. These efforts improve query accuracy for time-based analytics and reduce future defect risk, while elevating overall Rust code health and maintainability.
