Jun 1, 2025June 2025 — Delivered core feature enhancements, API cleanups, and build reliability improvements for gismo/gismo, driving faster iteration cycles, more robust mesh integration, and lower maintenance cost. Key features delivered include: range-based element iteration enabling clean loops and potential runtime gains; anonymous namespaces for qu-nodes to reduce symbol collisions; a new is_arithmetic template utility to simplify trait checks; and enhanced Element API with localId() access and updated setIntegrationDomain. API cleanup removed deprecated updateElement and unused includes to streamline public surface. Build and IO improvements (i/o cleanup, runner tag enablement, and wheel build fixes) improved packaging reliability. Bug fixes across division handling, generic fixes, and refinement improvements boosted correctness and stability. Together these changes reduce risk, accelerate development, and lay groundwork for future performance optimizations such as mult_expr specialization.
