- Introduced a new specification for adding an optional contact email field to events, including front-end output and compatibility testing. - Added a comprehensive design document for multi-day event occurrences, detailing the new occurrence data model, validation, normalization, and calendar architecture. - Created specifications for ACF field-key switching compatibility and local ACF override compatibility to ensure seamless integration with existing themes. - Implemented a desktop calendar view toggle design, allowing users to switch between calendar and list views, with persistent preferences and responsive behavior.
