 ## [Unreleased]
 
+## [1.51.4] - 2026-10-29
+
+### Security
+
+- **Next.js 15.5.28** (critical: remote code execution through the image optimiser with SVGs, and a
+  Server Actions denial of service), **@sentry/nextjs 10.78** (critical: middleware bypass),
+  **zod 4.6.7** (high: memory exhaustion on oversized collections; backend and frontend),
+  **multer 2.5.0** (high: denial of service from a pending file filter), **nodemailer 10.3.0**
+  (moderate: three address-parsing flaws that could add recipients), fast-uri 3.1.9 and
+  ip-address 10.7.5 (moderate). Minimum versions raised in package.json so a fresh install can't
+  resolve an older one. `npm audit`: frontend and root clean; the backend's 6 remaining reports are
+  low and dev-only (jest → deepmerge), with no real fix (npm suggests downgrading Jest to 25).
+
+### Changed
+
+- **cron-parser 5** (v4 is unmaintained): `CronExpressionParser.parse` in `src/jobs/index.js`.
+- **Node 24 LTS** for new installs (`scripts/install.sh`); Node 20 reached end of life in April 2026.
+  `deploy.sh` warns on servers older than Node 22; DEPLOYMENT.md has "Upgrading Node".
+- Roadmap: every endpoint moves to v2 before 2.0 (1.51.5 – 1.51.11).
+
+### Known
+
+- Still deprecated, with reasons: exceljs (unmaintained; brings fstream, glob 7, inflight,
+  lodash.isequal, rimraf 2) — replacing it with ExcelTS waits for approval; ESLint 9 (out of
+  support) — ESLint 10 needs Next.js 16 (1.51.5); @opentelemetry/sdk-trace-base — pulled in by the
+  latest @sentry/nextjs, for Sentry to update; glob 10 — inside Jest (dev only).
+
+## [1.51.3] - 2026-10-29
+
+### Changed
+
+- **Express 5** (from 4). Kept Express 4 behaviour where it changed: the `qs` ("extended") query
+  parser, and `req.body` as `{}` when a request has no JSON body. `@types/express` 5.
+- **The ticket scanner and at-the-door check-in use API v2** (`/api/v2/checkin/{qrCode}`). The v2
+  look-up now gives `attendee`, `bookedBy` and `ticketOptionId` (for section checks).
+- **Shared middleware answers in the v2 shape on /api/v2:** rate limits, the impersonation and
+  licence read-only guards, the auth checks and campus refusals write v1's `{ message, code }`;
+  on v2 that becomes `{ error: { code, message, reason } }` (`reason` = the specific old code, e.g.
+  `TWO_FACTOR_REQUIRED`, `LICENCE_READ_ONLY`). Read-only answers have the v2 code `READ_ONLY` (403).
+  The frontend's `apiFetch` treats `reason` like v1's `code`, so the 2FA and impersonation
+  handling works on v2 calls too.
+
+### Added
+
+- **v1 deprecation headers:** v1 endpoints that have a v2 replacement answer with
+  `Deprecation: @<date>` (RFC 9745) and `Link: <…>; rel="successor-version"` (`src/v2/deprecation.ts`).
+  The rest of v1 has no replacement yet, so no header.

+
