-## [Unreleased]
+## [2.21.0] — 2026-09-23
+
+### Added
+- **Setup makes sure you have a calendar to write to.** A fresh install could
+  finish onboarding and land on an empty grid with nothing saying why — either
+  because the device had no calendar at all, or because every calendar it had
+  was switched off. Setup now covers both: it offers to create a calendar on
+  this device or to add an account that syncs one, and it lists the calendars
+  that exist but are switched off so you can turn them back on ([#287]).
+
+### Changed
+- **The month grid gives its days more room.** Week numbers are set smaller and
+  their gutter is measured from the widest number it has to seat instead of
+  holding a fixed 40dp; event chips spend less of their width on padding; and
+  the labels in both are tracked more tightly, which is worth roughly a
+  character per chip ([#189], [#190], [#212], [#213]).
+- **A month day shows as many events as it has height for.** The limit was a
+  flat three at every size, so a tall week row threw away space it could have
+  filled, while a cramped one drew a third chip its band could not hold and put
+  the "more" marker below the clip, where nothing showed the day held more at
+  all. It is measured per week row now, and a tablet or a landscape phone seats
+  more of them.
+- **Split view no longer pads a short month out to six rows.** A five-row month
+  was handing the day pane a blank row and its gap — a sixth of the grid. The
+  grid now draws only the rows its month spans and the pane grows into the rest
+  ([#162]).
+
+### Fixed
+- **Short events show their title in week and day view.** A block needed 20dp
+  of height before it drew any title at all, which at fit-the-whole-day put the
+  cutoff around the half hour. The padding now tapers as the block shrinks, so
+  a short event keeps its name ([#289]).
+- **A fully zoomed-out timeline sits still.** Rounding its height up left it as
+  much as a pixel per hour taller than the viewport those hours are meant to
+  fill — some 24px of leftover scroll, enough to bounce off Android's
+  overscroll stretch ([#290]).
+- **Backup & restore says what is going on instead of coming up blank.** It
+  built its rows straight from the calendar list, so loading, a provider error,
+  and a device with nothing to export all rendered as an empty page with no
+  buttons on it ([#304]).
+- **An event with no title reads in your language.** It was labelled "(Ohne
+  Titel)" on every screen but the event's own, whatever language the phone was
+  set to: the German text was chosen before the translated one could be
+  ([#321]).
+- **A calendar the system gives no name reads in your language.** The same
+  cause, in the calendar lists and pickers — and because the calendar editor
+  starts from that name, saving such a calendar wrote the German text into it
+  for real ([#329]).
+
+## [2.20.4] — 2026-09-20
+
+### Fixed
+- **The app no longer reopens the event you last came in on.** Opening an event
+  from a reminder or a home-screen widget made the app return to that same
+  event on every later launch — and show an error screen once the event had
+  been deleted. Android hands an app the launch it was started with again each
+  time it is rebuilt, and Calendula was acting on it every time instead of
+  once ([#309]).
+- **"Today" works in the agenda again.** Scrolling a few days ahead and tapping
+  today did nothing, because the agenda is browsed by scrolling rather than by
+  moving its date, and the button only moved the date. It now brings the list
+  back to today, and it stays offered while the list is scrolled away — before,
+  it was hidden in exactly the situation it is for ([#305]).
+- **Calendula is filed under "Calendar & Agenda" in the self-hosted repo.**
+  Browsing by category in an F-Droid client set to prefer that repo listed the
+  app under "Time" instead ([#294]).
+
+## [2.20.3] — 2026-09-12
+
+### Fixed
+- **A custom agenda range crashed the app in French.** Choosing a custom range
+  for the agenda — or simply typing a number into that field — closed the app on
+  any phone set to French. The French translation of the "%d days" label was
+  missing the wording French uses for counts of two and above, and Android has
+  nothing to fall back on when that particular form is absent, so every value
+  except one day was affected ([#297], [#298]).
+
+## [2.20.2] — 2026-09-12
+
+### Fixed
+- **Crash reports are filed in English.** Reporting a crash from a phone set to
+  another language prefilled the issue — title and body — in that language, so
+  a French crash arrived on Codeberg as a French issue ([#297], [#298]). The
+  text that is *posted* is now English for everyone; the dialog that asks you
+  to send it, and everything else you see in the app, is still translated.
+
+## [2.20.1] — 2026-09-07
+
+### Fixed
+- **An empty calendar now explains itself.** "No calendars configured" offered
+  an "Open system calendar settings" button that opened nothing — every screen
+  wired it to the same reload that had just produced the empty state. It now
+  opens the system's account chooser, filtered to the providers that sync
+  calendars ([#239]).
+- **Calendars that are all switched off no longer look like an empty month.**
+  When every calendar on the device is hidden at system level there is nothing
+  to draw, but the app said nothing at all: it only ever checked whether the
+  device had *no* calendars, so a device that had them and hid them fell
+  through to a blank grid with no hint. That case now says so, and points at
+  Settings → Calendars — the one screen that can switch a calendar back on. The
+  navigation drawer's calendar list drew the same conflation and is fixed with
+  it ([#239]).
+
+## [2.20.0] — 2026-09-07
+
+### Added
+- **Long-press to copy.** Holding down the title, the location or the
+  description on an event puts that whole field on the clipboard. Tapping still
+  does what it always did — the location opens maps, a link in the description
+  opens — and the times, calendar, repeat rule and guests stay uncopyable. Below
+  Android 13 a short confirmation appears; from Android 13 on the system shows
+  its own clipboard chip ([#195]).
+- **The open-source projects Calendula ships** are now listed under Settings →
+  About, each with its copyright holder and licence, and each row tapping
+  through to that project's source ([#281]).
+
+### Changed
+- Event titles no longer end in an ellipsis. The "…" took the width of a couple
+  of characters and told you nothing you couldn't already see, so the title now
+  simply runs to the edge of its chip in the month, week and day views — a few
+  more letters per event, which is often the difference between two events you
+  can tell apart and two you can't. Right-to-left languages keep the ellipsis,
+  where clipping would cut the beginning of a title rather than its end
+  ([#164]).
+- Month-view events now show their start time before the title, where the chip
+  is wide enough to keep the title readable — in landscape, on a foldable and on
+  a tablet, and never at the cost of a narrow phone column. All-day events show
+  no time, and neither does a bar carried in from the previous week, whose start
+  is not in that row. Event times across the month, week and day views are also
+  set in a regular weight against the title's, so a time reads as a time rather
+  than as part of the name next to it ([#219]).
+- **The hour lines in week and day view are now an hour grid.** The setting
+  that drew a faint separator line at each hour now seats every hour in its own
+  rounded cell, so an hour boundary reads as the seam between two surfaces
+  rather than a line drawn across one — the same negative space that separates
+  the month grid's days and the week's columns. An event that starts on the hour
+  fills its cell instead of overhanging the seam, and one that runs past
+  midnight still meets the edge of its column ([#113]).
+- **An invitation you haven't answered now reads as an outline.** An event still
+  waiting on your reply is drawn with the calendar's colour on its border and
+  its title and nothing behind it, so it stands apart from the ones you have
+  accepted — on the month chips, the all-day bars and the week and day blocks
+  alike. Declined events keep their filled, struck-through chip and now sort
+  last in the month view as well, so a day with more events than fit drops the
+  ones you said no to first ([#230]).
+- The calendar titles now shorten instead of being cut off. When the full month
+  name doesn't fit the top bar, the month and week views fall back to its
+  three-letter form and the day view drops the weekday, rather than trailing off
+  mid-word at large font sizes. The view switcher, the title and the agenda's
+  range bar also line up with the grid underneath them ([#165]).
+- The jump-to-today button in the toolbar now shows today's date. It drew a
+  generic calendar icon, which told you nothing you didn't already know from
+  tapping it; it now carries the current day number in an outlined box, so the
+  bar says what day it is as well as taking you there. It rolls over at midnight
+  on its own ([#220]).
+- The quick-switch pill disappears when there is nothing left to switch between,
+  and you can now turn calendar views off all the way down to a single one — the
+  setting used to hold two open purely to keep the pill fed ([#150]).
+
+### Fixed
+- **A long location no longer runs off the edge of its field.** The location on
+  the edit screen sat on one line, so a full postal address or a long meeting
+  link scrolled sideways out of sight as you typed it. It now wraps and the card
+  grows to fit, with the pin and the contacts button staying level with the first
+  line at any font size. A multi-line address you paste in is joined with commas
+  — the way one picked from your contacts always has been — instead of running
+  together into a single word ([#273]).
+- **The event form capitalizes sentences again.** The title, description and
+  guest fields had stopped starting a sentence with a capital letter; they
+  follow the keyboard's usual behaviour once more. The location is deliberately
+  left alone, since it is as often a URL as an address ([#146]).
+- **A block you pick up no longer loses its second line.** Dragging an event
+  whose time or title wrapped to two lines clipped the floating copy to one line
+  for as long as you held it, and it snapped back on drop. The copy now measures
+  its text exactly as the block does ([#267]).
+
+## [2.19.4] — 2026-09-01
+
+### Fixed
+- **A deleted occurrence no longer comes back when the series is re-timed.**
+  Delete a single occurrence of a repeating event, then change the time of the
+  whole series, and the occurrence you had removed reappeared. Doing it the
+  other way round — "This and all following events" — lost every removal in the
+  part of the series being changed. Removals now travel with the event: they
+  keep their place in the series across a time change, a move to a different
+  day, a timezone change and a switch to or from an all-day event, and they
+  carry over when a series is split. Repeating events on your device's own
+  calendars are affected, including the birthday and anniversary calendars
+  Calendula creates from your contacts ([#248]).
+- **Home-screen widgets now turn the page at midnight.** Both the month and the
+  agenda widget kept highlighting yesterday as "today" — and the agenda kept
+  greying out the wrong events as already past — until you paged the month back
+  and forth or removed and re-added the widget. Calendula now wakes itself at the
+  day boundary and redraws, and re-arms after a reboot, a clock change or a
+  flight into another timezone. Paging the month widget forward and back also
+  stops quietly pinning it to that month, so it follows the date again instead of
+  being stranded on the month you happened to be looking at ([#228]).
+- **"Only this event" now actually saves your edit.** On some calendars —
+  including Google ones that still show as on-device, and any local calendar —
+  editing a single occurrence of a repeating event did nothing at all: the scope
+  dialog closed, the edit screen stayed put, and saving again just repeated it.
+  Android can only attach a single-occurrence change to its series once the
+  calendar has been synced at least once, so on those calendars the change had
+  nowhere to go. Calendula now removes that one occurrence from the series and
+  saves the edit as its own event instead, which is what you see either way. A
+  save that does fail also says so for longer, rather than flashing past
+  ([#234]).
+- **A failed import no longer costs you the whole file.** One event the calendar
+  refuses used to abort the entire import with nothing on screen but "couldn't
+  read this file". Events are now added one at a time: anything rejected is
+  counted and shown, and the rest still arrive. A faulty repeat rule in the file
+  is repaired instead of being handed on ([#225]).
+- **All-day reminders survive a backup and an import.** They fire at the hour you
+  chose, not at midnight UTC — the same rule the app already applied to all-day
+  events you create yourself — and an export no longer leaves them out of the
+  file entirely. An imported yearly birthday fires at the right hour too, even
+  though the file dates it back to the year of birth ([#225]).
+- **Birthdays and anniversaries imported from Fossify Calendar now show up.**
+  Fossify writes the ones it mirrors from your contacts as events that start and
+  end on the same day, which the calendar read as lasting no time at all: they
+  imported without complaint and then appeared nowhere. Any all-day event that
+  ends where it starts, or carries no end at all, is now a one-day event
+  ([#225]).
+- **A backup no longer brings back occurrences you had deleted.** Remove a single
+  occurrence of a repeating event, back up, restore — and it was there again,
+  because the removals never made it into the file. They travel with the series
+  now, so a restored calendar looks the way you left it ([#225]).
+- **A reminder left on your account's default no longer went off as the event
+  started.** An event whose reminder says "Default" is the account's to time, not
+  Calendula's — it was reading that setting as a lead time of its own and firing a
+  minute after the event began. It now leaves such a reminder alone, and says so
+  on the event.
+- **"Only this event" on an event that doesn't repeat now edits or deletes it.**
+  Deleting used to write an exclusion onto a one-off event instead — which left
+  the event there and lost its end time — and editing filed the change away as an
+  exception to nothing, so it vanished.
+- **An import that the calendar cuts short now tells you how far it got.** Losing
+  the calendar or the permission part way through a big file reported the whole
+  import as failed, so importing again added everything twice.
+- **An event that runs past midnight can be dragged by either half.** Its second
+  half couldn't be picked up at all, and the first could only be moved later. Both
+  halves now move, and both are previewed while you hold either one, so the event
+  reads as moving rather than growing. The blocks are cut square at midnight
+  instead of rounded off, a month row draws an event crossing into the next week
+  as one bar, and a move across a daylight-saving change no longer lands an hour
+  out ([#253]).
+
+### Added
+- **More of an imported `.ics` survives the trip**: tasks come across as events
+  rather than being dropped in silence, deleted occurrences of a repeating event
+  stay deleted, a calendar named like the one the file came from is preselected,
+  and event colours are carried over — matched to the closest colour your
+  calendar's account offers, so a migrated calendar still reads at a glance
+  ([#225]).
+- **Belarusian, Hungarian and Slovak**, all three contributed as community
+  translations through
+  [Calendula's Weblate](https://weblate.dev.jeanlucmakiola.de/projects/calendula/).
+  Belarusian covers about nine tenths of the app, Slovak about a third and
+  Hungarian is just under way, so untranslated parts still show in English until
+  they fill out. Pick any of them under Settings → Language or in Android's
+  per-app language settings. Thanks to Dmitri Gabinski (Belarusian), Ábel Nagy
+  (Hungarian) and Julie (Slovak); help finishing them is very welcome.
+
+### Changed
+- **Arabic, Polish and Simplified Chinese are now complete**, all three carried
+  the rest of the way this cycle — Simplified Chinese from a fifth of the app to
+  all of it. Czech and Russian grew too — Russian to about half — and still have
+  room. Thanks to Sup99999 (Arabic), Bazyli Cyran (Polish), JeanWenzel
+  (Simplified Chinese), James Trivette (Czech), and SpiritOTHawk and Artur
+  (Russian).
