@@ -5,6 +5,135 @@ All notable changes to this project will be documented in this file.

+## [2.14.0] — 2026-07-06
+
+### Added
+- Restore events from a backup file. The backup section of Settings can now read
+  events back **in** from an `.ics` file, not just write one out: pick a file,
+  choose which calendar to import into, and Calendula adds the events — skipping
+  any that are already there and telling you how many it skipped. Export gained a
+  per-calendar selector at the same time, so you can back up just the calendars
+  you pick instead of everything at once ([#32]).
+- Week numbers in Month view. A new **Week numbers** setting (off by default)
+  adds a slim gutter down the left of the Month grid showing the calendar-week
+  number for each row, sized to match the day cells. Handy if you plan or refer
+  to dates by week number ([#25]).
+- Tap a date header to open that day. In Week and Agenda view, tapping a date
+  header now opens that date in Day view — the same drill-in that Month view and
+  the agenda widget already offered, so every view behaves the same way. It makes
+  jumping to a specific day quicker: switch to Week, swipe to the week you want,
+  then tap the date to open it. Thanks to @ptab for the suggestion ([#37]).
+- An early Simplified Chinese translation. Calendula has started speaking
+  Simplified Chinese, contributed as a community translation through
+  [Calendula's Weblate](https://weblate.dev.jeanlucmakiola.de/projects/calendula/).
+  It is still an early effort, so many parts of the app show in English until it
+  fills out — you can already pick it under Settings → Language or in Android's
+  per-app language settings. Thanks to
+  [zh-cn](https://weblate.dev.jeanlucmakiola.de/user/zh-cn/) for getting it
+  started; help finishing it is very welcome.
+
+### Changed
+- Long event titles wrap in the edit screen. When editing an event, a long title
+  now wraps onto multiple lines instead of being clipped to a single line, so you
+  can see and edit the whole thing ([#33]).
+
+## [2.13.1] — 2026-07-06
+
+### Added
+- Create events from other apps and widgets. Calendula now registers the
+  standard "insert event" intent (`ACTION_INSERT` on the calendar events type),
+  so other apps and home-screen widgets — such as the Todo Agenda widget — can
+  hand off to Calendula to create a new event. It opens the new-event form
+  prefilled with whatever they passed (title, start/end time, all-day, location,
+  description, recurrence), and picks your last-used or first writable calendar.
+  Thanks to @dschuermann for the suggestion ([#30]).
+
+### Fixed
+- Some recurring events could not be opened. Events in a series that started
+  before 1970 — for example yearly birthdays or anniversaries synced over CalDAV
+  — showed "Something went wrong" instead of opening, because their stored start
+  time is a negative value that was wrongly treated as invalid. They now open
+  normally and appear in search again. A related case (an event whose stored end
+  precedes its start) is now kept and openable instead of failing the same way.
+  Thanks to @dschuermann for the report ([#34]).
+- The time picker now follows your 24-hour setting. With Calendula set to
+  24-hour time, the clock dial for choosing an event's start and end time still
+  showed AM/PM instead of a 24-hour dial; it now matches your setting (and the
+  same fix applies to the all-day reminder time in Settings). Thanks to
+  @abrossimow for the report ([#27]).
+
+## [2.13.0] — 2026-07-03
+
+### Added
+- Calendula now speaks Spanish and Italian. Both arrived as community
+  translations through [Calendula's Weblate](https://weblate.dev.jeanlucmakiola.de/projects/calendula/)
+  — a **huge thank you** to
+  [kikerw](https://weblate.dev.jeanlucmakiola.de/user/kikerw/) for the Spanish
+  translation and to
+  [corrent](https://weblate.dev.jeanlucmakiola.de/user/corrent/) for the Italian
+  one! Pick your language under Settings → Language or in Android's per-app
+  language settings. Strings added in this very release may still show in
+  English until the translations catch up. Want Calendula in your language?
+  Translating happens entirely in the browser — every contribution is welcome.
+- See your contacts' birthdays and anniversaries in your calendar. A new,
+  **optional** feature (Settings → Contact special dates) mirrors your contacts'
+  birthdays, anniversaries and other dates into local "Birthdays",
+  "Anniversaries" and "Other dates" calendars that stay in sync as your contacts
+  change. Each is a normal local calendar, so you set its colour, visibility and
+  reminders the usual way — new birthdays even start with a reminder a week before
+  *and* on the day. The title format is yours to customise (`{name}`, `{year}`).
+  This is the first feature to use the contacts permission: it is requested only
+  when you turn the feature on, everything stays on your device (Calendula has no
+  internet access), and your contacts are only ever read, never changed. Thanks
+  to @moonj for the suggestion ([#15]).
+- Set more than one default reminder per calendar. A calendar's default
+  reminders — and the global defaults under Settings → Notifications — can now
+  hold several lead times instead of just one, so new events can start with, say,
+  a reminder a week before *and* one on the day. The reminder pickers are now
+  multi-select; per-calendar overrides can still inherit the global default or
+  turn reminders off entirely. Thanks to @moonj for the suggestion ([#14]).
+- Widget headers now open the app. Tapping the month/year title on the month
+  widget opens the app on the month view, and tapping the "Upcoming" title on
+  the agenda widget opens it on your default view — so there's a one-tap way
+  back into the app that lands where you'd expect, instead of only through a day
+  or event. On the month widget, tapping anywhere on a day — not just the small
+  date number — now opens that day, and the "today" button snaps the grid back
+  to the current month in place. Thanks to @rgz46vic and @ptab for the
+  suggestions ([#18], [#20]).
+- Make Calendula's text your own. Settings → Appearance gains **Headings font**
+  and **Body font** pickers: keep the system default, choose a bundled face
+  (Atkinson Hyperlegible, Lora, JetBrains Mono — each previewed in its own
+  face), or load any `.ttf`/`.otf` file from your device, independently per
+  role. Font size and colour stay with Android's accessibility scaling and the
+  app theme, as discussed on the issue. Thanks to @abrossimow for the
+  suggestion ([#19]).
+- Choose what the view-switch button cycles through. Settings → Appearance now
+  lets you pick which views the top-right quick-switch button rotates between
+  and drag them into your preferred order; views you switch off stay reachable
+  from the navigation menu, which can be reordered the same way. Thanks to
+  @abrossimow for the suggestion ([#24]).
+
+### Fixed
+- Month widget arrows and "today" button work again. On release builds the
+  prev/next-month arrows and the jump-to-today control on the month widget did
+  nothing when tapped — code shrinking had stripped the tap handlers behind
+  them. They respond again. Thanks to @rgz46vic for the report ([#18]).
+- Disabled calendars no longer notify. Reminders for events in a calendar you
+  have disabled (Settings → Calendars) are now suppressed instead of still
+  popping up — matching how a disabled calendar's events already stay hidden
+  everywhere else in the app ([#17]).
+- Editing a single occurrence of a recurring event works again. Choosing **Only
+  this event** and saving a change to one event in a repeating series silently
+  did nothing — the change was rejected and the edit form simply reappeared with
+  nothing applied. The edited occurrence is now stored correctly, so the change
+  lands on just that one event and leaves the rest of the series untouched
+  ([#16]).
+- Every calendar can be picked when creating an event. The event editor's
+  calendar picker was a fixed-height dialog, so with many calendars anything
+  past the first nine or so was simply unreachable. It is now a full-screen,
+  scrollable list grouped by account, with each calendar's colour shown.
+  Thanks to @dschuermann for the report ([#29]).
