Jul 1, 2025July 2025 monthly summary for knime/webapps-common. Focused on stabilizing dropdown UX and clarifying value display for edge cases. Delivered two targeted bug fixes with user-facing impact and completed release hygiene tasks to improve traceability. Key outcomes included: (1) robust handling of empty possible values in dropdowns with an empty-state presentation and a patch addressing Python node loading animation when values are empty; CHANGELOG updated; version bumps applied. (2) Improved display logic for SingleSelectControl when a selected value ID cannot be matched to available options, showing the raw value to avoid confusion. (3) Release hygiene: version bumps and changelog updates to ensure visibility of changes across downstream consumers.
