Fixes categories that could go missing after you created an account or joined a multi-user plan, along with saved entries that stopped showing the category you filed them under. The first sync after updating puts them back, with nothing for you to do. Your entries themselves were never changed. Only the category shown against them went missing. Sharing an account no longer removes a category of your own because the person you share with has one by the same name. Both are kept.

Your Caffeinated calendars stay one calendar. Signing in on another device no longer leaves you with a second copy of the same calendar, and copies you already have are merged back together, events and all. Your events reach every device. In a calendar synced with your Caffeinated account, an event created on one device can now be edited and deleted from another, instead of the change being quietly dropped on its way to the server. A single occurrence you move or edit keeps its own place in the series, instead of overwriting the rest of it or coming back as a duplicate. Week and Days now open at the hour your day starts. Changing that hour under Day hours in Settings takes effect right away.

Your older events show up: calendars now load history as you scroll, with a new Sync history setting and a Sync diagnostics screen. Allow tasks on CalDAV calendars that accept them without advertising support, like Fastmail. Deleting a CalDAV account now removes it cleanly, and duplicates are recognized as one. Offline changes retry until they reach the server. Interface polish on iPhone and iPad.

Reminders: create one and get nudged at the time you pick. Snooze from the notification, organize with tags, and keep them apart from your events and tasks. Two new ways to see your week: Grid shows day cards at a glance, and Days is a 2-7 day timeline. Quick Add now creates reminders and to-dos from what you type, not just events. A new Font size setting scales the whole app. Fixed: CalDAV calendars added without a color no longer show unreadable text in widgets.

Fixes a problem with subscribing after a trial ends.

New Widget theme preference picks System, Light, or Dark, independently of the app's theme, so you can run Caffeinated Calendar in one mode and your widgets in the other. On Android, widget titles that disappeared on some launchers in dark mode are readable again. Events created from a task on the desktop app now ride along with sync. Tap the new Linked task chip on the event, or the Linked event chip on the task, to jump between them.

Additional widgets added, a Grid View showing the next few days and a mini-calendar, and a Tasks view. CalDAV calendars from your other devices no longer duplicate when you sign in. The 24-hour time and Week Starts On preferences are honored in notifications and the event/task editors. Caffeinated Calendar is now available for Windows, macOS, and Linux at caffeinatedcalendar.com.

Tasks got a major upgrade: a home-screen widget, subtasks with drag-to-reorder, manual ordering that persists across devices, and In Progress / Cancelled status badges. Sync is faster and more reliable. Completing a task or saving an event no longer waits on the network. Recurring CalDAV events keep their full schedule. Startup is noticeably faster. Caffeinated Calendar is now available for Windows, macOS, and Linux at caffeinatedcalendar.com.

Self-hosted CalDAV servers with self-signed certificates now work. The app asks whether to trust the certificate on first connect, and warns you if it ever changes later.

You can now send feedback, suggestions, and bug reports directly from the app drawer. Tap "Send Feedback" to share what you'd like to see next.
