CHANGELOG.md

@@ -5,6 +5,98 @@ All notable changes to this project will be documented in this file.
 The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.1.0/),
 and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).
 
+## [2.12.0] — 2026-06-28
+
+### Added
+- See past events your way. Two new settings change how events that have already
+  ended are shown. **Past events** (Settings → Appearance → Agenda) lets the
+  agenda — both in the app and the home-screen "Upcoming" widget — keep them as
+  usual, dim them, or hide them from the list entirely. **Dim completed events**
+  (Settings → Appearance) separately fades finished events in the month and week
+  views. Both are off by default, an event only counts as finished once it has
+  actually ended (events still in progress are never dimmed), and the lists
+  update on their own as the day goes on. Thanks to @ptab for the suggestion
+  ([#12]).
+
+### Changed
+- Readable titles on overlapping events. In the week and day views, events that
+  overlap split a day into slim columns where the title used to be clipped to a
+  character or two. The title now wraps across as many lines as the block can
+  fit, and the time is hidden on those narrow blocks so the name can fill the
+  space — so you can tell events apart without opening each one. Thanks to @ptab
+  for the suggestion ([#13]).
+
+## [2.11.2] — 2026-06-28
+
+### Added
+- Jump straight to typing a title. When you start a new event, Calendula now puts
+  the cursor in the title field and opens the keyboard right away, so you can type
+  the name without an extra tap. It's on by default and only affects creating an
+  event — editing never grabs focus — and a new **Focus title on new event**
+  switch (Settings → New event form) turns it off. Thanks to @abrossimow for the
+  suggestion ([#10]).
+
+## [2.11.1] — 2026-06-28
+
+### Fixed
+- Calendula can now be set as your default calendar app. It registers the
+  calendar-app intent filters the system uses, so it appears in the chooser when
+  you tap a date in a launcher or clock — and opening one takes you straight to
+  that day. Android has no way for an app to make itself the default, so you pick
+  it once from the system picker. Thanks to @abrossimow for the report ([#9]).
+
+## [2.11.0] — 2026-06-27
+
+### Added
+- Start the week on any day. The **Week starts on** setting (Settings →
+  Appearance) now offers every weekday — not just Monday or Sunday — alongside
+  the automatic, locale-based default. Thanks to @zmaherdev for the suggestion
+  ([#3]).
+- Choose a 12- or 24-hour clock. A new **Time format** setting (Settings →
+  Appearance) lets you force a 12-hour (2:00 PM) or 24-hour (14:00) clock, or
+  follow the system setting automatically. It applies everywhere times appear —
+  the week and day timelines, agenda, event details, search and reminders — so
+  the format is now consistent across the whole app. Thanks to @zmaherdev for
+  the suggestion ([#6]).
+- Optional hour lines in the timeline. A new **Hour lines** switch (Settings →
+  Appearance) draws a faint separator at each hour in the week and day views,
+  making it easier to see when events start and end. Off by default. Thanks to
+  @zmaherdev for the suggestion ([#5]).
+- Limit how far ahead the agenda looks, and switch it on the fly. New **Agenda
+  range** and **Agenda widget range** settings (Settings → Appearance) let the
+  agenda screen and its home-screen widget each show just today, the rest of this
+  week, the rest of this month, a rolling 7 or 30 days, or a custom number of
+  days — "This week" follows your week-start. The agenda also gains a bar at the
+  top naming the exact dates in view, with a button to switch the range just for
+  the current session (it resets when you reopen the app); the bar can be turned
+  off. Thanks to @zmaherdev for the suggestion ([#4]).
+- Automatic backup of local calendars. A new **Automatic backup** option
+  (Settings → Calendars → Backup) periodically exports your local calendars to an
+  `.ics` file in a folder you choose, on an interval you set (from 30 minutes up).
+  Useful for file-based syncing such as Syncthing, or simply as a safety net — it
+  is a one-way export and never touches your synced accounts. Thanks to @shield
+  for the discussion that inspired it ([#7], [#8]).
+- Field icons in the event-form settings. Each optional-field toggle (Settings →
+  Event form) now shows the same icon the field uses in the new-event form, so
+  the list is easier to scan.
+- Help translate Calendula. A **Help translate** link at the top of **Settings →
+  App language** opens the project's Weblate, where you can add or improve a
+  language in your browser — no coding needed. Contributions in any language are
+  welcome.
+
+### Changed
+- Tidied **Settings → Appearance** into clearer groups (theme & colour, calendar,
+  agenda), and the agenda's empty state now reads "You're all caught up".
+- Reworked **Settings → Calendars**. Local and synced calendars are now grouped
+  into collapsible, source-branded cards — each account shows its app's icon —
+  with a per-account menu to enable or disable all of its calendars at once or
+  open the account in its source app.
+- Reorganised **Settings → Notifications**: reliable-delivery and snooze settings
+  moved up with the other global reminder options, and the per-calendar reminder
+  overrides now fold into a single expandable section.
+- Moved **Add Quick Settings tile** out of the event-form section to its own
+  top-level entry in Settings.
+

+### Added
+- Start the week on any day. The **Week starts on** setting (Settings →
+  Appearance) now offers every weekday — not just Monday or Sunday — alongside
+  the automatic, locale-based default. Thanks to @zmaherdev for the suggestion
+  ([#3]).
+- Choose a 12- or 24-hour clock. A new **Time format** setting (Settings →
+  Appearance) lets you force a 12-hour (2:00 PM) or 24-hour (14:00) clock, or
+  follow the system setting automatically. It applies everywhere times appear —
+  the week and day timelines, agenda, event details, search and reminders — so
+  the format is now consistent across the whole app. Thanks to @zmaherdev for
+  the suggestion ([#6]).
+- Optional hour lines in the timeline. A new **Hour lines** switch (Settings →
+  Appearance) draws a faint separator at each hour in the week and day views,
+  making it easier to see when events start and end. Off by default. Thanks to
+  @zmaherdev for the suggestion ([#5]).
+- Limit how far ahead the agenda looks, and switch it on the fly. New **Agenda
+  range** and **Agenda widget range** settings (Settings → Appearance) let the
+  agenda screen and its home-screen widget each show just today, the rest of this
+  week, the rest of this month, a rolling 7 or 30 days, or a custom number of
+  days — "This week" follows your week-start. The agenda also gains a bar at the
+  top naming the exact dates in view, with a button to switch the range just for
+  the current session (it resets when you reopen the app); the bar can be turned
+  off. Thanks to @zmaherdev for the suggestion ([#4]).
+- Automatic backup of local calendars. A new **Automatic backup** option
+  (Settings → Calendars → Backup) periodically exports your local calendars to an
+  `.ics` file in a folder you choose, on an interval you set (from 30 minutes up).
+  Useful for file-based syncing such as Syncthing, or simply as a safety net — it
+  is a one-way export and never touches your synced accounts. Thanks to @shield
+  for the discussion that inspired it ([#7], [#8]).
+- Field icons in the event-form settings. Each optional-field toggle (Settings →
+  Event form) now shows the same icon the field uses in the new-event form, so
+  the list is easier to scan.
+- Help translate Calendula. A **Help translate** link at the top of **Settings →
+  App language** opens the project's Weblate, where you can add or improve a
+  language in your browser — no coding needed. Contributions in any language are
+  welcome.
+
+### Changed
+- Tidied **Settings → Appearance** into clearer groups (theme & colour, calendar,
+  agenda), and the agenda's empty state now reads "You're all caught up".
+- Reworked **Settings → Calendars**. Local and synced calendars are now grouped
+  into collapsible, source-branded cards — each account shows its app's icon —
+  with a per-account menu to enable or disable all of its calendars at once or
+  open the account in its source app.
+- Reorganised **Settings → Notifications**: reliable-delivery and snooze settings
+  moved up with the other global reminder options, and the per-calendar reminder
+  overrides now fold into a single expandable section.
+- Moved **Add Quick Settings tile** out of the event-form section to its own
+  top-level entry in Settings.

+### Fixed
+- Calendula can now be set as your default calendar app. It registers the
+  calendar-app intent filters the system uses, so it appears in the chooser when
+  you tap a date in a launcher or clock — and opening one takes you straight to
+  that day. Android has no way for an app to make itself the default, so you pick
+  it once from the system picker. Thanks to @abrossimow for the report ([#9]).

+### Added
+- Jump straight to typing a title. When you start a new event, Calendula now puts
+  the cursor in the title field and opens the keyboard right away, so you can type
+  the name without an extra tap. It's on by default and only affects creating an
+  event — editing never grabs focus — and a new **Focus title on new event**
+  switch (Settings → New event form) turns it off. Thanks to @abrossimow for the
+  suggestion ([#10]).

+### Added
+- See past events your way. Two new settings change how events that have already
+  ended are shown. **Past events** (Settings → Appearance → Agenda) lets the
+  agenda — both in the app and the home-screen "Upcoming" widget — keep them as
+  usual, dim them, or hide them from the list entirely. **Dim completed events**
+  (Settings → Appearance) separately fades finished events in the month and week
+  views. Both are off by default, an event only counts as finished once it has
+  actually ended (events still in progress are never dimmed), and the lists
+  update on their own as the day goes on. Thanks to @ptab for the suggestion
+  ([#12]).
+
+### Changed
+- Readable titles on overlapping events. In the week and day views, events that
+  overlap split a day into slim columns where the title used to be clipped to a
+  character or two. The title now wraps across as many lines as the block can
+  fit, and the time is hidden on those narrow blocks so the name can fill the
+  space — so you can tell events apart without opening each one. Thanks to @ptab
+  for the suggestion ([#13]).
