Aug 1, 2025

August 2025: Delivered core UI robustness and API modernization for posit-dev/py-shiny. Highlights include input component hardening (select inputs restricted to strings to prevent HTML in labels and correct rendering of reserved HTML characters), date input flexibility (empty strings represent null/unset values with proper clearing and constraint handling via input_date, input_date_range, update_date, and update_date_range), a new full_screen option for navigation cards to ensure a consistent fullscreen UI, and a modernization of the navigation API by deprecating ui.update_navs in favor of ui.update_navset. These changes improve user experience, reduce UI edge-case bugs, and provide a clearer, future-proof API, enabling safer defaults, easier maintenance, and faster downstream development.
