 ## [Unreleased]
 
+## [1.21.0] - 2026-10-19
+
+### Added
+
+- Post-event feedback, set up in a new Feedback step in the event wizard.
+  - Questions use the form builder.
+  - You pick when it's sent (the default is the morning after the event) and who gets it: everyone who checked in, or everyone registered.
+  - Each person gets a personal link by email (and WhatsApp where they use it).
+  - Anyone who hasn't answered gets one reminder 3 days later.
+  - Answers can be anonymous or named.
+  - "Send now" is available, and the questions lock once people start answering.
+- New form field types: **Rating (1–5 stars)** and **Multiple choice**. They're used for feedback, and can also go on attendee forms (registration page, My Events, the kiosk, manual registration and Supervisor → Forms).
+- New report, **Feedback summary**:
+  - response rate;
+  - average rating per question, with star distribution;
+  - multiple-choice and yes/no breakdowns as bar charts;
+  - a list of text answers (with names unless the form is anonymous).
+  - Select several events to compare their ratings (e.g. Camp 2025 vs Camp 2026). Exports to PDF and Excel like other reports.
+- New `/api/feedback` endpoints and a job every 15 minutes (`FEEDBACK_JOB_ENABLED=false` to turn it off).
+  - Requires the `add_feedback_forms` database migration.
+
+## [1.20.0] - 2026-10-19
+
+### Added
+
+- Sponsor a spot: a new event setting, "Allow sponsorships" (event wizard → Sponsor a spot).
+  - It adds a "Sponsor a spot" button on the event page so people can fund a place for someone who can't afford it.
+  - Sponsors choose one or more whole spots (at the main ticket price) or a custom amount, and pay through Yoco. Guests just give a name and email.
+  - Sponsors can give anonymously, or add a name and a message for the organisers.
+  - An optional goal ("12 of 20 spots sponsored") and public progress bar.
+- Each sponsorship is recorded as a donation tagged to the event, in that event's sponsorship pool.
+  - Supervisors assign pool money to registrations with the existing donation assign/unassign flow, fully or partly.
+  - Under Payments → Donations, sponsorships are labelled, there's an "Only the sponsorship pool" filter, and the sponsor's message is shown.
+  - Who receives help is never shown to sponsors.
+- Sponsors get a "Thank you for sponsoring a spot" receipt.
+  - Automations has a new "Thank Your Sponsors" email for events with sponsorships.
+  - Email attendees can target an event's sponsors (`filter.audience: 'sponsors'`).
+- The Donations breakdown report has sponsorship pool columns per event: received, assigned and remaining.
+- New `/api/sponsorships` endpoints.
+  - Requires the `add_sponsorships` database migration.
+
+## [1.19.0] - 2026-10-19
+
+### Added
+
+- Rooms & groups (Supervisor → Rooms & groups), for camps and lockdowns: put attendees into rooms, cabins, small groups, teams or buses.
+  - Each event can have several allocation sets (e.g. "Rooms" and "Buses"). Each set has groups with an optional capacity, an optional gender restriction and an optional leader (a staff member).
+  - A drag-and-drop board puts people not yet placed on the left and groups, with capacity counters, on the right. Full groups and groups for the other gender won't accept a person.
+  - Auto-allocate fills groups evenly with everyone not yet placed, respecting capacity and gender. It can keep people on the same booking together or spread them out.
+  - Printable lists per group (with leader) and a master list. On youth events they can include medical and emergency details from consent forms; viewing those is recorded in the audit log.
+  - "Show on tickets" prints the group on each person's ticket and shows it in My Events.
+  - Email and WhatsApp attendees can be sent to one group ("Bus 2 leaves at 07:30"). Messages go to whoever booked for the people in it.
+  - Group leaders see their people under Staff → My groups. Medical details are shown to supervisors only.
+- New event setting "Ask each person's gender" (under Named attendees). It adds a gender choice for each named person on the registration page, at the door, on the kiosk, in manual registration and in My Events, and is needed for gender-split rooms.
+- New `/api/allocations` endpoints.
+  - Requires the `add_room_allocation` database migration.
+
+## [1.18.0] - 2026-10-19
+
+### Added
+
+- Ticket transfer. On My Events, "Transfer" hands a ticket to someone else before the event: enter their name and email or phone.
+  - The new holder gets the ticket by email/WhatsApp with a new QR code. If they're new, an inactive account is created and they get an activation link.
+  - The old QR code stops working, so screenshots of it won't scan. Scanning it says who the ticket was transferred to, and offline-mode sync flags it.
+  - For a ticket covering several people, one place is split off to the new holder.
+  - The payer stays responsible for the registration.
+- Transfer rules:
+  - Only before the event starts, and only for tickets that haven't been scanned.
+  - It can be turned off per event (new "Ticket transfer" setting in the event wizard, on by default). Supervisors can always transfer, from At the door → Tickets.
+  - On youth events, the new holder's date of birth, and a parent's details for a minor, are needed, and a new consent request is sent.
+  - The previous holder's attendee form answers and consent medical details are removed.
+  - Every transfer is recorded in the audit log.
+- New endpoints `POST /api/tickets/:id/transfer` and `GET /api/tickets/:id/transfers`.
+  - Requires the `add_ticket_transfer` database migration.
+
+## [1.17.0] - 2026-10-19
+
+### Added
+
+- Offline ticket scanning. While online, staff pick an event and section on the scanner and tap "Enable offline mode". The section (or the whole event) is locked to their device and its tickets are downloaded to the device.
+  - With no connection, scans are checked against that list and queued on the device.
+  - The panel shows when the list was downloaded and how many scans are waiting.
+  - Queued scans sync automatically when the device is back online (or with "Sync now"), and check-in messages go out then.
+  - "Release section" ends offline mode and deletes the list from the device.
+- Only one device can hold a section at a time (a whole-event lock clashes with every section). While a section is locked, other devices see who holds it and can't scan it, online or offline, so a ticket can never be redeemed twice by two offline devices.
+- Syncing is idempotent and never redeems more than is left on a ticket. Anything that needs a person to look goes into a sync report: tickets not found, cancelled registrations, used-up tickets, scans outside the locked section, and check-ins without consent.
+- Supervisor → Offline scanning page: active locks with force release (for a lost or flat phone; its scans still sync if it reconnects, and are flagged), and sync reports to review. Locks, releases, force-releases and syncs are recorded in the audit log.
+- The scanner is installable as an app (web app manifest), and a service worker caches the scanner page and its scripts so it opens with no connection.
+- The app now stays signed in with the last confirmed profile when it's reloaded without a connection, instead of sending the user to the login page.
+- New `/api/scan-locks` endpoints.
+  - Requires the `add_offline_scanning` database migration.
+
+### Changed
+
+- `POST /api/tickets/scan/:qrCode` now accepts `sectionId` and checks it on the server; this was previously only checked in the browser.
+  - It now refuses (423) scans in a section that another device has locked for offline scanning.
+

+- Yoco checkout metadata carries `type: 'sponsorship'`. The webhook records the payment as `isDonation` + `isSponsorship` against the event, together with `sponsorName`, `sponsorMessage` and `sponsorAnonymous`.
+- Pool funds are assigned with `PUT /api/payments/assign-donation`.

+| GET | `/api/tickets/:id/transfers` | payer, holder or staff+ | Transfer history |
+
+Rules:
+- Only before the event starts, and only for tickets that have never been scanned.
+- `Event.allowTicketTransfer` turns it off for non-supervisors.
+
+What a transfer does:
+- The new holder becomes the ticket's attendee and gets a new QR code. A shared ticket for several places has one place split off into its own ticket.
+- An account is matched by email/phone, or created inactive with an activation link.
+- The previous holder's attendee form answers are deleted, and the medical details on their consent are cleared. A minor on a youth event gets a new consent request.
+
+Old QR codes:
+- `scan-preview` and `scan` return `410 { code: "TICKET_TRANSFERRED" }`.
+- Offline sync reports them as `transferred`.
+- Each transfer is audited as `ticket_transferred`.
+
+## Offline scanning
+
+| Method | Path | Auth | Description |
+|--------|------|------|-------------|
+| GET | `/api/scan-locks?eventId=` | staff+ | Active offline locks for an event |
+| POST | `/api/scan-locks` | staff+ | Lock `{ eventId, sectionId?, deviceId, deviceName? }` to this device (409 if the scope is held elsewhere) |
+| GET | `/api/scan-locks/:id/snapshot?deviceId=` | staff+ | Tickets valid in the lock's scope (lock holder only) |
+| POST | `/api/scan-locks/:id/sync` | staff+ | `{ deviceId, scans: [{ clientScanId, qrCode, qty, scannedAt }] }` — idempotent; returns accepted, duplicates, conflicts |
+| DELETE | `/api/scan-locks/:id` | staff+ | Release (`{ deviceId }`, lock holder only) |
+| POST | `/api/scan-locks/:id/force-release` | supervisor+ | Release a lost device's lock |
+| GET | `/api/scan-locks/reports?eventId=&unreviewed=` | supervisor+ | Sync reports |
+| POST | `/api/scan-locks/reports/:id/review` | supervisor+ | Mark a report reviewed |
+
+How locks work:
+- One device per scope. A whole-event lock (`sectionId` null) clashes with every section lock on that event.
+- `POST /api/tickets/scan/:qrCode` now accepts `sectionId` and `deviceId`. It enforces the section on the server, and returns `423 { code: "SCAN_LOCKED" }` when another device holds a lock covering the ticket.
+
+How syncing works:
+- Synced scans never redeem more than is left on a ticket.
+- Conflicts are recorded in the sync report: `not_found`, `cancelled`, `wrong_scope`, `already_used`, `partly_used` and `consent`.
+- Check-in messages are sent after the sync.
+- Locks, releases, force-releases and syncs are written to the admin audit log.

 - **QR code scanner** — check people in by scanning their ticket with any phone camera. A single ticket can cover a whole family and be checked in a few people at a time.
+- **Feedback after every event** — a short survey with star ratings goes out automatically the morning after, with one reminder. See response rates and compare this year's camp with last year's.
+- **Sponsor a spot** — let your congregation fund places for people who can't afford to come, with an optional "12 of 20 spots sponsored" progress bar. You decide who receives the help; sponsors never see who.
+- **Rooms & groups for camps** — drag campers into cabins, small groups or buses (or auto-fill by capacity and gender), print lists for leaders, and show the cabin on each ticket.
+- **Ticket transfer** — can't make it? Pass your ticket on to a friend; they get a fresh QR code and the old one stops working.
+- **Works without Wi-Fi** — lock a check-in point to a phone and keep scanning with no signal; scans sync automatically when the connection is back.
 - **Scan points** — set up separate check-in points (e.g. main hall, dinner) that only accept the right tickets.
 - **At-the-door desk** — search by name, phone, or ticket number; register walk-ins; take cash, card, or EFT payments; check people in; and print or resend tickets on the spot.
 - **Self-service kiosk** — set up a tablet where visitors register themselves. Returning visitors are recognised by their email or phone number.
