+
+## 2025-10-05 — New features & changes
+### Added
+- Postgres persistence support for the backend (requires `DATABASE_URL`). Backend will auto-create `servers`, `invites`, and `users` tables on startup.
+- `backend/pg.js` helper module to manage Postgres connection and CRUD helpers.
+- `backend/.env.example` updated to show `DATABASE_URL` with a Tailscale IP example (100.111.50.59).
+- Short-lived invite token flow (HMAC) for delete authorization (default, via `INVITE_TOKEN_SECRET`).
+- Frontend invite UI fixes (copy/delete handlers, confirmation dialog) and various UI polish updates.
+
+### Changed
+- Backend now requires `DATABASE_URL` by default; no automatic fallback to encrypted `db.json` for persistence.
+- `INVITE_API_KEY` static option deprecated in favor of short-lived invite tokens; token issuance endpoint remains unauthenticated (recommendation: restrict in production).
+
+### Fixed
+- Async/await handler fixes and small bug fixes across backend endpoints.
+
+### Notes
+- Existing encrypted `backend/db.json` is retained but no longer used by the running backend. A migration script to import old data into Postgres is planned but not yet implemented.
+
+### Documentation
+- README updated with setup steps, Postgres guidance, migration note, and expanded app description.
+
+### Added
+- Live Notifications: per-guild Twitch live notification settings (backend endpoints, frontend UI, and bot command to configure). Stored in server settings under `liveNotifications`.
+
+## 2025-10-06 — Improvements & housekeeping
+### Changed
+- Backend now enforces `DATABASE_URL` as the primary persistence store. If `DATABASE_URL` is unset the server will refuse to start. This ensures all server settings and invites are stored in Postgres consistently.
+- Server-Sent Events (SSE) endpoint `/api/events` added to allow the frontend to receive real-time updates (command toggles, twitch users updates, live-notifications updates) without refresh.
+- `discord-bot/twitch-watcher.js` logging reduced to avoid per-guild spam; announcements are concise and errors still reported.
+- Command deployment logs are aggregated (single summary line) to avoid flooding logs with per-guild messages.
+
+### Added
+- `/internal/test-live` dev endpoint (backend) & `announceLive` bot helper to force live announcements for debugging.
+
+### Fixed
+- Frontend `ServerSettings.js` now subscribes to SSE and updates commands, watched users and live settings in real-time when backend publishes events.
+- Help command updated to produce a neat Embed and support `/help <command>` for detailed usage; help lists read from backend to remain future-proof.
+
+
+
+## [Previous] - 2025-10-04
+### Added
+- Initial full-stack integration (React frontend, Express backend, Discord bot) and file-based encrypted persistence.
+- Dashboard and server settings UI components.
+- Invite creation, listing and deletion endpoints and UI.
