+
+### Attendee editing *(Tier 5 #12, opened 2026-06-22)*
+
+The last read-only gap in the event model: attendees are read & shown on the
+detail screen (since v0.6) but the form can't write them. Make guests editable.
+
+- **Read side already done:** `Attendee` domain model + status/relationship/type
+  enums, `queryAttendees` + `EventDetailMapper.toAttendee` (with tests), and the
+  attendees `DetailCard` + `AttendeeRow` in `EventDetailScreen`. Nothing to add
+  there.
+- **Write side — SHIPPED (`feat/attendee-editing`, commit b0f34ff, 2026-06-22):**
+  `attendees` on `EventForm`; a Guests section in `EventEditScreen` rendered as an
+  inline grouped list — each guest a tonal card (avatar, name/email, tappable
+  Required/Optional role chip, remove), the trailing card an inline email field
+  (type → Done commits). Persisted by `reconcileAttendees` diffing the provider's
+  `CalendarContract.Attendees` rows on insert + dirty-checked update (new guests =
+  `RELATIONSHIP_ATTENDEE` / `STATUS_INVITED`; kept rows keep their status, only the
+  required/optional type updates; organizer/resource/no-email rows untouched).
+  Reminders restyled to the same grouped-list pattern in passing. Needs only the
+  existing `WRITE_CALENDAR` — no new permission.
+- **Name on manual add — SHIPPED via a contact picker** (2026-06-22). The inline
+  field is email-only (the quick path); the add row also has a **"from contacts"
+  button**: `ACTION_PICK` on `ContactsContract.CommonDataKinds.Email.CONTENT_URI` →
+  the system Contacts app returns a URI to the picked email row, queried for
+  `Email.ADDRESS` **and** the contact `DISPLAY_NAME`, so a picked guest gets both
+  email and name in one tap. The result Intent grants temporary read access, so
+  **no `READ_CONTACTS` permission** — one-shot and user-driven, same no-permission
+  mechanism as the location address picker above. Self/organizer rows stay
+  non-editable.
+- **Invitation behavior — DECIDED 2026-06-22: record-only, all writable
+  calendars.** Calendula has no INTERNET and never sends an invitation itself; it
+  only writes `Attendees` rows. Whether a guest is notified is decided downstream:
+  local calendars notify no one (no sync); CalDAV/DAVx5 PUTs the `ATTENDEE` lines
+  and the *server* decides iMIP delivery; Google's sync adapter pushes the change
+  and Google decides (third-party attendee writes are historically unreliable
+  there). Editing is allowed on **any writable calendar** — not gated to local.
+  - **Honest, backend-aware copy is mandatory** (this is the whole point of the
+    decision): on a synced calendar show "Calendula doesn't send invitations —
+    your calendar account may email guests when it syncs"; on a local calendar
+    show "Stored on this device. No one is notified."
+  - Calendula must **not fabricate an ORGANIZER** or otherwise fake scheduling
+    state to coax a send — it writes the guest list faithfully and leaves
+    scheduling entirely to the backend.
+  - The optional "send an .ics invite via your email app" delegate (`ACTION_SEND`,
+    still no INTERNET) was considered and **deferred** — revisit only if users ask
+    to notify guests explicitly.
+- **Out of scope (for now):** RSVP/your-own-response editing, free/busy lookups,
+  resource booking — all carry server round-trips or richer sync semantics.

 ## Next

-1. Monitor the F-Droid build/publish for the v2.4.0 tag
-2. Decide the "Locations & People" and "remote calendar create/edit"
-   go/no-go calls (both hinge on the INTERNET permission) — see `ROADMAP.md`
-3. **Duplicate event** and **jump-to-date** are the cheap follow-ups; then
-   agenda view (strategic, backs a future widget). Full ranked sequence in
-   `ROADMAP.md` → "Near-term sequence".
+1. Cut **v2.8.0** from `release/v2.8.0` (bump versionName → tag via the
+   merge-driven pipeline) once on-device review signs off
+2. **Attendee editing** — the committed next feature (Tier 5 #12, high-
+   importance, opened 2026-06-22). Attendees are already read & shown on the
+   detail screen since v0.6; the gap is the write side — make guests editable
+   in `EventEditScreen` / `EventForm` (add by typed email, role, remove),
+   persisted by diffing `CalendarContract.Attendees`. No new permission for the
+   typed-email path. **Invitation behavior DECIDED 2026-06-22: record-only on all
+   writable calendars** — Calendula never sends (no INTERNET); honest backend-aware
+   copy ("your account may email guests when it syncs" on synced calendars, "no one
+   is notified" on local). Full sketch in `ROADMAP.md` → "Attendee editing".
+3. Then: the two INTERNET go/no-go calls (OSM autocomplete, remote calendar
+   create/edit) and Tier 2/3 leftovers (quick-settings tile, now-line, week
+   numbers in month, full-text search, accessibility pass). Drag-and-drop
+   rescheduling is **rejected**.

-## [Unreleased]
+## [2.9.0] — 2026-06-25
+
+### Added
+- Choose the view Calendula opens on. A new **Default view** setting (Settings →
+  Appearance) lets you pick Month, Week, Day or Agenda as the view shown each
+  time you start the app, instead of always opening on Week. Thanks to
+  @devinside for the suggestion ([#1]).
+- The month widget is now interactive: tap any day to open it, or tap an event to
+  open its details. Previously only the month's prev/next/today controls
+  responded. Thanks to @devinside for spotting this ([#2]).
+- Predictive back. Swiping back from a screen — an event, the editor, search or
+  settings — now follows your finger, shrinking the screen to preview what's
+  behind so you can see where Back will take you before you let go; slide it back
+  to cancel. The preview needs Android 14 or newer; on older versions Back works
+  as before.
+- Respect for "Remove animations". If you've turned animations off in your
+  device's Accessibility settings, Calendula now honours it everywhere: motion
+  collapses to a quick fade and the back preview is skipped.
+
+### Changed
+- Smoother, more consistent motion throughout. Expanding sections, list updates
+  in search and agenda, and the onboarding screens now animate the same way
+  across the app, instead of some places sliding or growing while others popped
+  in. Switching between Month, Week, Day and Agenda now cross-fades rather than
+  snapping, while paging within a view keeps its slide.
+
+### Fixed
+- Home-screen widgets now back out the way you came in. A day or event opened
+  from the Agenda widget keeps you in the agenda context, and from the Month
+  widget in the month context — pressing Back returns there instead of dropping
+  you on the week view. More broadly, the app now keeps a real view history:
+  switching views and drilling into a day are retraced by Back one step at a
+  time, down to your default view before the app exits. Thanks to @devinside for
+  reporting ([#2]).
+
+## [2.8.0] — 2026-06-23
+
+### Added
+- Find events fast. A search button in the top bar of every calendar view opens
+  a search box — type a couple of letters and matching events (by title,
+  location or description) appear, soonest first with past events below. Tap a
+  result to open it. Search covers your whole calendar, not just what's on
+  screen, and skips calendars you've hidden. A recurring event shows its next
+  occurrence rather than the date the series first started.
+- A current-time line in the day and week views. A thin coloured line marks the
+  present moment across today's column, so you can see at a glance where you are
+  in the day. It updates every minute and only appears when today is in view.
+- Add and remove event guests. The create/edit form now has a Guests section:
+  add people by email or pick them from your contacts, mark each as required or
+  optional, and remove them. Calendula never sends invitations itself (it has no
+  internet access) — it only records the guests; if the event lives on a synced
+  account, that account may email them when it syncs, and on a local calendar no
+  one is notified. The form tells you which applies. Picking a guest from
+  contacts needs no contacts permission.
+- Pick a location from your contacts. A contacts button beside the location
+  field drops a contact's address straight into an event — handy for a meeting
+  at someone's home or office. Like the guest picker, it needs no contacts
+  permission.
+- A "New event" Quick Settings tile. Add it to your quick settings to jump
+  straight into the new-event form from anywhere. Settings → New event has a
+  one-tap button to add the tile (Android 13+); on older versions you can add it
+  from the quick-settings editor.
+- Snooze and dismiss buttons on reminder notifications. Dismiss clears the
+  reminder; snooze hides it and brings it back after a delay you pick in
+  Settings → Notifications (5 to 60 minutes, default 10). Android's calendar
+  system won't re-post a reminder on its own, so Calendula schedules an exact
+  alarm to bring a snoozed one back on time.
+
+### Changed
+- Event details now show each guest's email beneath their name, instead of only
+  when no name is available.
+- Crash and problem reports now open on the project's public Codeberg tracker,
+  where anyone can register and file an issue. Nothing is sent automatically —
+  you still review the report and submit it yourself in the browser.

+### Added
+- Find events fast. A search button in the top bar of every calendar view opens
+  a search box — type a couple of letters and matching events (by title,
+  location or description) appear, soonest first with past events below. Tap a
+  result to open it. Search covers your whole calendar, not just what's on
+  screen, and skips calendars you've hidden. A recurring event shows its next
+  occurrence rather than the date the series first started.
+- A current-time line in the day and week views. A thin coloured line marks the
+  present moment across today's column, so you can see at a glance where you are
+  in the day. It updates every minute and only appears when today is in view.
+- Add and remove event guests. The create/edit form now has a Guests section:
+  add people by email or pick them from your contacts, mark each as required or
+  optional, and remove them. Calendula never sends invitations itself (it has no
+  internet access) — it only records the guests; if the event lives on a synced
+  account, that account may email them when it syncs, and on a local calendar no
+  one is notified. The form tells you which applies. Picking a guest from
+  contacts needs no contacts permission.
+- Pick a location from your contacts. A contacts button beside the location
+  field drops a contact's address straight into an event — handy for a meeting
+  at someone's home or office. Like the guest picker, it needs no contacts
+  permission.
+- A "New event" Quick Settings tile. Add it to your quick settings to jump
+  straight into the new-event form from anywhere. Settings → New event has a
+  one-tap button to add the tile (Android 13+); on older versions you can add it
+  from the quick-settings editor.
+- Snooze and dismiss buttons on reminder notifications. Dismiss clears the
+  reminder; snooze hides it and brings it back after a delay you pick in
+  Settings → Notifications (5 to 60 minutes, default 10). Android's calendar
+  system won't re-post a reminder on its own, so Calendula schedules an exact
+  alarm to bring a snoozed one back on time.
+
+### Changed
+- Event details now show each guest's email beneath their name, instead of only
+  when no name is available.
+- Crash and problem reports now open on the project's public Codeberg tracker,
+  where anyone can register and file an issue. Nothing is sent automatically —
+  you still review the report and submit it yourself in the browser.

+### Added
+- Choose the view Calendula opens on. A new **Default view** setting (Settings →
+  Appearance) lets you pick Month, Week, Day or Agenda as the view shown each
+  time you start the app, instead of always opening on Week. Thanks to
+  @devinside for the suggestion ([#1]).
+- The month widget is now interactive: tap any day to open it, or tap an event to
+  open its details. Previously only the month's prev/next/today controls
+  responded. Thanks to @devinside for spotting this ([#2]).
+- Predictive back. Swiping back from a screen — an event, the editor, search or
+  settings — now follows your finger, shrinking the screen to preview what's
+  behind so you can see where Back will take you before you let go; slide it back
+  to cancel. The preview needs Android 14 or newer; on older versions Back works
+  as before.
+- Respect for "Remove animations". If you've turned animations off in your
+  device's Accessibility settings, Calendula now honours it everywhere: motion
+  collapses to a quick fade and the back preview is skipped.
+
+### Changed
+- Smoother, more consistent motion throughout. Expanding sections, list updates
+  in search and agenda, and the onboarding screens now animate the same way
+  across the app, instead of some places sliding or growing while others popped
+  in. Switching between Month, Week, Day and Agenda now cross-fades rather than
+  snapping, while paging within a view keeps its slide.
+
+### Fixed
+- Home-screen widgets now back out the way you came in. A day or event opened
+  from the Agenda widget keeps you in the agenda context, and from the Month
+  widget in the month context — pressing Back returns there instead of dropping
+  you on the week view. More broadly, the app now keeps a real view history:
+  switching views and drilling into a day are retraced by Back one step at a
+  time, down to your default view before the app exits. Thanks to @devinside for
+  reporting ([#2]).
