- Added a new data structure `ScheduleChanges` to represent changes when a university document is republished. - Implemented methods to read and write changes to a local JSON file. - Enhanced the `Repository` class to detect changes between the current and fresh timetable versions. - Updated the `MainViewModel` to expose changes to the UI and handle marking changes as seen. - Created UI components for displaying changes in both Home and Settings screens. - Added support for changes in iOS views, including a new `ChangesCard` and `ChangesSheet`. - Implemented logic to compare timetable versions and identify added, removed, and changed lessons.
