Mar 1, 2026

March 2026 monthly summary for rust-lang/rust-project-goals: Delivered a targeted roadmap/template overhaul centered on Project Zero, including structural revisions (design axioms before outcomes), consolidation of key use cases into a succinct aspirational statement, and routing goals through the new ROADMAP ROWS directive with what-and-why metadata. Re-scoped and renamed roadmaps to emphasize Project Zero, introduced The Borrow Checker Within, and redefined Polonius-related goals (Renamed Polonius to Stabilize and model Polonius Alpha; added a Full Polonius future row) to align with the overall soundness initiative. Introduced TaskTree to generalize subgoals and fix task owners for 2026+ goals, added subgoals to roadmap-tagged goals, and created specific-deliverable subgoals for several areas to improve granularity and accountability. Enhanced highlight reporting with HIGHLIGHT TABLE and HIGHLIGHT CREDITS directives, added narrative prose for highlights, and surfaced contributors under each highlight table to improve transparency and team recognition. Improved quality and governance across the board: cargo fmt, dynamic heading handling, robust first_sentence parsing, RFC generation/documentation pipeline, and injected task owners into roadmap metadata to improve traceability and maintainability, delivering clearer progress signals to stakeholders and stronger business value.
