October 2025 (2025-10) monthly summary for GenSpectrum/dashboards focusing on delivering business value through dependency modernization, UX improvements for the W-ASAP dashboard, and solid code quality. Key accomplishments include: modernization of dependencies across the batch (bumping components to 1.8.0/1.8.1 and upgrading dashboard-components to 1.8.2) to improve security, performance, and compatibility; extensive W-ASAP UI enhancements such as cov-spectrum mutation links, numerical sliders, a Zürich default city filter, enhanced date range options, and Jaccard index filtering; dynamic untracked exclusion list and a dedicated help modal to improve usability and data integrity. Architecture and quality improvements were pursued through refactors moving lapis functions into a common package, use of imported types, TSConfig improvements with React import removal, standardizing W-ASAP field names, and ApplyFilterButton and InfoBlock component refactors, complemented by ESLint cleanup and testing enhancements.
