+## [Unreleased]
+
+## [2.14.1] — 2026-07-13
+
+### Fixed
+- Deleting one occurrence of a repeating event no longer breaks the series.
+  Choosing "This event" when deleting an occurrence of a recurring event could
+  wipe out every *other* occurrence while leaving the one you deleted behind as
+  a stale, still-tappable ghost — and deleting it again brought the series back.
+  A single-occurrence delete now removes exactly that occurrence and leaves the
+  rest of the series untouched, and the deleted occurrence disappears from the
+  grid straight away. This holds on every kind of calendar, including the
+  on-device ones Calendula keeps for contact birthdays and anniversaries, where
+  the series is a yearly repeat. Thanks to @moonj for the report ([#47]).
+- Tapping an event in a third-party widget opens it in Calendula. v2.13.1 taught
+  Calendula to answer the "new event" hand-off from other apps and widgets; now
+  it also answers the "open this event" one, so tapping an existing event in a
+  widget such as Todo Agenda offers Calendula and lands on that event's details.
+  Thanks to @bushrang3r for the report ([#48]).
+- Events created from other apps get your default reminder. An event handed over
+  by another app or widget — Google Maps' "add to calendar", the Todo Agenda
+  widget's "+" — opened with no reminder at all, ignoring the default set in
+  Settings. It now starts with your default reminder, the same as an event you
+  create in Calendula. An event opened from an `.ics` file is treated differently,
+  because the file has its own say: Calendula keeps whatever reminders it carries
+  (including none at all) and asks you once whether to apply your default instead
+  — it never quietly overrides the file. If you have no default set, it doesn't
+  ask ([#49]).
+- A tidy colour picker on CalDAV calendars. For calendars synced by a CalDAV
+  app (such as DAVx5), the event colour picker showed every colour the account
+  publishes — nearly 150 swatches in alphabetical order, many of them
+  duplicates or near-identical shades. The picker now shows only visually
+  distinct colours, arranged as a rainbow; near-duplicate shades and the
+  washed-out neutrals are folded away so no two swatches look alike. Picked
+  colours still sync exactly as before, and calendars with hand-picked
+  palettes (like Google's) are unaffected. Thanks to @ptab for the report
+  ([#22]).
+
+## [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]).

+ * Curates an account's published event palette for the colour picker.
+ *
+ * Sync adapters differ wildly in what they publish: Google exposes a
+ * hand-picked two-dozen set, while CalDAV adapters (DAVx5) dump all ~147 CSS3
+ * named colours — including exact-value aliases (aqua/cyan, the gray/grey
+ * spelling pairs) and dozens of visually indistinguishable whites and grays
+ * (#22).
+ *
+ * Crucially, curation runs against the colour the picker actually *paints*, not
+ * the raw provider value. The picker softens every swatch through [pastelArgb]:
+ * it pins lightness to a constant and caps saturation, so the raw palette's
+ * lightness axis is invisible on screen. Two raw colours that look different —
+ * a navy and a mid blue — paint as one swatch, and every neutral (black, the
+ * grays, white) paints as the same pale tint. Judging distinctness in raw
+ * space, as before, left near-identical painted swatches and stranded the
+ * neutrals as a run of look-alike "pinks" at the end of the grid.
+ *
+ * Three steps, all in painted space:
+ *  1. Collapse swatches that paint identically to one (alphabetically-first key
+ *     wins, deterministically) — this folds aliases, dark/light shades of a
+ *     hue, and all the neutrals together.
+ *  2. Oversized palettes (> [CURATION_TRIGGER_SIZE]) drop the washed-out
+ *     neutral-origin tints (painted chroma < [PASTEL_CHROMA_FLOOR]) and are
+ *     then thinned to visually distinct colours: most vivid first, a colour is
+ *     kept only when at least [MIN_DELTA_E] (CIE76, painted Lab) from every
+ *     colour already kept. Small palettes are already curated by their adapter
+ *     and pass through whole.
+ *  3. The survivors are ordered like a rainbow — continuously by painted hue —
+ *     with the wheel cut at its single widest empty gap so the one unavoidable
+ *     seam lands in dead space and no hue family is torn across both ends.
+ *
+ * Every surviving option keeps its provider [EventColorOption.key], so a pick

+### 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]).

+### Fixed
+- Deleting one occurrence of a repeating event no longer breaks the series.
+  Choosing "This event" when deleting an occurrence of a recurring event could
+  wipe out every *other* occurrence while leaving the one you deleted behind as
+  a stale, still-tappable ghost — and deleting it again brought the series back.
+  A single-occurrence delete now removes exactly that occurrence and leaves the
+  rest of the series untouched, and the deleted occurrence disappears from the
+  grid straight away. This holds on every kind of calendar, including the
+  on-device ones Calendula keeps for contact birthdays and anniversaries, where
+  the series is a yearly repeat. Thanks to @moonj for the report ([#47]).
+- Tapping an event in a third-party widget opens it in Calendula. v2.13.1 taught
+  Calendula to answer the "new event" hand-off from other apps and widgets; now
+  it also answers the "open this event" one, so tapping an existing event in a
+  widget such as Todo Agenda offers Calendula and lands on that event's details.
+  Thanks to @bushrang3r for the report ([#48]).
+- Events created from other apps get your default reminder. An event handed over
+  by another app or widget — Google Maps' "add to calendar", the Todo Agenda
+  widget's "+" — opened with no reminder at all, ignoring the default set in
+  Settings. It now starts with your default reminder, the same as an event you
+  create in Calendula. An event opened from an `.ics` file is treated differently,
+  because the file has its own say: Calendula keeps whatever reminders it carries
+  (including none at all) and asks you once whether to apply your default instead
+  — it never quietly overrides the file. If you have no default set, it doesn't
+  ask ([#49]).
+- A tidy colour picker on CalDAV calendars. For calendars synced by a CalDAV
+  app (such as DAVx5), the event colour picker showed every colour the account
+  publishes — nearly 150 swatches in alphabetical order, many of them
+  duplicates or near-identical shades. The picker now shows only visually
+  distinct colours, arranged as a rainbow; near-duplicate shades and the
+  washed-out neutrals are folded away so no two swatches look alike. Picked
+  colours still sync exactly as before, and calendars with hand-picked
+  palettes (like Google's) are unaffected. Thanks to @ptab for the report
+  ([#22]).

+Calendula es una aplicación de calendario moderna y de código abierto
+para Android. Funciona directamente sobre el proveedor de calendario del
+sistema: cualquier origen sincronizado en tu dispositivo — Nextcloud
+mediante DAVx5, Google, calendarios locales, suscripciones WebCal —
+aparece automáticamente, y los cambios que hagas se sincronizan de vuelta
+del mismo modo.
+
+Crea, edita y elimina eventos, incluidos los recurrentes con cambios
+acotados (solo este evento / este y todos los siguientes / toda la serie)
+y un sencillo selector de repetición. Calendula también entrega los
+recordatorios de tus eventos como notificaciones: toca una y estarás en
+el evento.
+
+Si quieres, muestra en tu calendario los cumpleaños, aniversarios y otras
+fechas especiales de tus contactos. Tú mismo lo activas; los contactos se
+leen solo en tu dispositivo, nunca se suben y nunca se modifican —
+Calendula solo refleja las fechas en calendarios locales que controlas
+por completo.
+
+El factor diferenciador es el diseño: auténtico Material 3 Expressive en
+toda la aplicación, con Dynamic Color, movimiento expresivo y formas
+expresivas.
+
+Privacidad: cero telemetría, sin analíticas, sin acceso a la red — tus
+datos nunca salen del dispositivo.
