-## 8. Managing Casdoor yourself
+## 8. Stack changes in this release
+
+- **One PostgreSQL instance.** The separate casdoor-postgres container is
+  gone: the app DB (`procurement`) and Casdoor's DB (`casdoor`) now live on
+  the same `postgres:18` service. The `casdoor` role + database are created
+  by `sql/02-casdoor-db.sql` on a fresh volume; the migration was done via
+  `pg_dump`/`pg_restore` (pre-migration backups are kept on the host).
+- **Traefik v3 is the public edge.** Ports 80/443 (web/websecure); host rules
+  for app / api / auth / s3 / storage (env-overridable, localhost defaults).
+  The frontend nginx now only serves the SPA and proxies `/api` internally.
+  Production (real domains, Let's Encrypt, HTTP→HTTPS redirect) is a one
+  command with `docker-compose.prod.yml` — see its header for the env vars.
+  Note: Traefik must be **v3.6+** (≤3.3 fails against Docker Engine 29.x),
+  and the docker socket is mounted read-write (Docker Desktop rejects `:ro`).
+- **RBAC hardening (Organization / Admin).** Only the `admin` can change
+  roles (`PATCH /users/{id}`); the procurement manager can only assign
+  projects to project managers. The user-creation form is removed — users
+  come from Casdoor via `POST /users/sync` (identity mirroring, roles
+  untouched). The admin has a dedicated panel at `/admin` (sync + grant/
+  revoke «مدیر تدارکات»).
+- **Developer Mode is now a 3-step admin flow** on the login page: admin
+  credentials → role switcher (ادمین / مدیر تدارکات / مدیر پروژه) → role-based
+  routing (admin → `/admin`, manager → office, PM → inventory).
+- **Partial goods receipt** in «کالاهای در راه»: submitting any item with a
+  valid quantity is enough; the rest stays in transit. The ledger shows
+  «رسیده X از Y» / «در راه Z» and a «رسید جزیی» badge on the quote. The
+  arrival-confirmation 500 (a `db.begin()` on an already-begun session) was
+  fixed, and the receipt response now returns the real derived state.
+- **Daily control calendar** now renders day-of-month (was rendering the
+  Jalali year), navigates by real Jalali months, and uses pure Jalali dates
+  («امروز ۸ شهریور ۱۴۰۵»), with a blue accent on today and a ring on the
+  selected day.
+- **Uploads** (invoice/proforma) no longer send `Content-Type: application/json`
+  on multipart requests — the 400/422 «دادهی ارسالشده نامعتبر است» is fixed.
+- **Project filter** in the admin inventory views is fixed: empty/undefined
+  query params are dropped (previously `project_id=undefined` → 400 → empty
+  dropdowns).
+
+## 9. Managing Casdoor yourself

   you can manage Organizations, Users, Applications, Providers, Certificates.
