May 2025 performance summary: Focused on delivering high-value features, stabilizing the codebase, and improving user-facing documentation. The NURBS Surface Miniapp received arbitrary-resolution sampling and enhanced visualization capabilities, with a new jittering option. CI/build and repository hygiene improvements were applied across mfem/mfem and related dfem/minisurface code, including documentation updates and file renames to improve stability and maintainability. The dFEM minimal surface was moved to a miniapp, and install docs were updated for Enzyme on RHEL9. Workshop content was corrected (broken hyperlink) and seminar pages were refreshed with up-to-date speaker details, slides, and recordings. Overall impact: higher visualization fidelity, reduced maintenance burden, and more accessible, accurate materials for users and collaborators.
