Dec 1, 2025December 2025 (2025-12) monthly summary for duckdb/duckdb-web focuses on documentation improvements to enhance developer experience and reduce ambiguity around histogram usage. The month’s work centered on clarifying examples and constraints in the docs, rather than implementing new features or fixing major bugs. This aligns with business goals of faster onboarding, better API understanding, and reduced support overhead. Key outcomes include improved guidance for histogram vs histogram_exact usage and explicit notes about formatting constraints (e.g., padding not combinable with thousands separator in SQL formatting functions). These changes help developers write correct queries straight away and decrease friction in using histogram functions.
