Jan 1, 2025January 2025 — Focused on API clarity and data integrity around object representation in Oscar.jl. Implemented a developer-facing documentation update that warns against mutating data or generating cached information as a side effect of printing objects. This prevents subtle bugs in data representation and aligns printing semantics with expectations, improving reproducibility and maintainability. No functional feature releases or bug fixes were deployed this month; the primary accomplishment is documentation-driven risk reduction and clearer API semantics for developers and users.
