+- **v0.4.1 — App Filtering + Bugfixes:**
+  - **Filter bar on Alkalmazások page**: Four pill-shaped filter buttons (Mind/Futó/Leállítva/Telepíthető) with live count badges computed from DOM. Filters stack cards via `display: none`, updates URL with `?filter=running` via `history.replaceState`. Reads filter from URL on page load for deep-linking support.
+  - **New `filterCategory` template function** (`funcmap.go`): Maps container state + deployed flag to filter categories (running/stopped/available). Each stack card gets a `data-filter-state` attribute for client-side filtering.
+  - **Clickable dashboard stat cards**: Stat cards (Futó/Leállítva/Összes) changed from `<div>` to `<a>` with `href` linking to `/stacks?filter=running`, `/stacks?filter=stopped`, `/stacks` respectively. Hover effect with translateY + box-shadow.
+  - **docker-compose.yml synced to demo node**: Fixed the stale compose file that still had `dashboard.${DOMAIN}` Traefik label (from pre-v0.3.0). Now uses correct `felhom.${DOMAIN}` label + `/sys:/host/sys:ro` mount.
+  - **Controller version:** v0.4.1 — deployed and verified on demo-felhom.eu
+  - **Remaining manual tasks for Viktor (Task 2 & 3 from TASK.md):**
+    - Verify `felhom.demo-felhom.eu` resolves correctly (Cloudflare Tunnel public hostname may need updating from `dashboard.*` to `felhom.*`)
+    - Update Pi-hole local DNS if applicable
+    - Enable backup in `controller.yaml` on demo node (`backup.enabled: true`)
+    - Create `/srv/backups` directories on demo node
