Feb 1, 2025February 2025 (molgenis/molgenis-emx2) focused on enhancing configurability, robustness, and data integrity. Key features delivered include a settings-driven footer system replacing the static Footer.vue, with demo-page integration, enabling non-developers to tailor UI footers via application settings; and an Improved input validation framework with integer/decimal checks and early long-validation refactor to catch issues sooner. A critical bug fix ensured biobank selections remain robust when services/collections are missing by treating them as empty arrays, preventing runtime errors and improving selection logic.
