Calendaring features and CalDAV support

The software introduced practical improvements that matter in daily use: you can set multiple alarms for a single event, CalDAV support and server interoperability were strengthened, and overall stability, performance, and memory usage saw measurable gains. These changes make scheduling and updating entries faster and more dependable when you work with calendars hosted on compatible services. citeturn2view0
