+# Felhom Hub — Changelog
+
+## v0.2.0 (2026-02-20)
+
+**Customer Configuration Management**
+
+New "Configurations" section for pre-provisioning customer nodes. Operators can configure
+customer settings in the Hub web UI, then `docker-setup.sh` downloads a ready-made
+`controller.yaml` — reducing deployment to a customer ID and password.
+
+### New features
+
+- **Web UI — `/configs` pages:**
+  - List all customer configurations in a table
+  - Create new configuration: customer identity, infrastructure secrets (CF tunnel/API tokens),
+    git sync credentials, monitoring UUIDs — organized in collapsible sections
+  - Detail page: shows credentials (retrieval password, per-customer API key) with copy-to-clipboard,
+    setup commands (`docker-setup.sh` and `curl`), live YAML preview
+  - Edit and delete configurations
+  - Navigation tabs (Dashboard / Configurations) on all pages
+
+- **Config retrieval API — `GET /api/v1/config/{customer_id}`:**
+  - Authenticated via `X-Retrieval-Password` header (separate from Bearer token)
+  - Generates complete `controller.yaml` by deep-merging template with customer overrides
+  - Template sourced from `controller.yaml.example` (fetched from Gitea repo periodically)
+  - Falls back to embedded default template if fetcher not configured
+
+- **Per-customer API keys:**
+  - Each customer config gets its own API key (auto-generated, 64 hex chars)
+  - Controllers can authenticate with per-customer key instead of the shared global key
+  - Backward compatible — global `report_api_key` continues to work alongside per-customer keys
+
+- **YAML generation (`internal/configgen` package):**
+  - Deep-merge of template + customer-specific overrides
+  - Programmatic injection: customer identity, hub config, session secret
+  - Shared by both API handler and web UI preview
+
+- **Template fetcher (background goroutine):**
+  - Periodically fetches `controller.yaml.example` from Gitea (configurable interval)
+  - Requires `registry.username` + `registry.token` in hub.yaml
+  - Falls back to `go:embed` default template when not configured
+
+- **Data layer:**
+  - New `customer_configs` SQLite table
+  - 6 CRUD methods: Save, Get, List, Delete, GetByAPIKey, UpdateRetrievalPassword
+
+### Configuration
+
+New `registry` section in `hub.yaml`:
+
+```yaml
+registry:
+  image: "gitea.dooplex.hu/admin/felhom-controller"
+  username: ""               # Gitea credentials (for version checker + template fetcher)
+  token: ""
+  check_interval: "6h"
+  template_interval: "1h"   # How often to refresh controller.yaml.example
+```
+
+### Files added
+
+- `internal/configgen/configgen.go` — shared YAML generation package
+- `internal/web/configs.go` — web handlers for config CRUD
+- `internal/web/templatefetcher.go` — background template refresh
+- `internal/web/controller.yaml.default` — embedded fallback template
+- `internal/web/templates/configs.html` — config list page
+- `internal/web/templates/config_form.html` — create/edit form
+- `internal/web/templates/config_detail.html` — detail + credentials page
+
+### Files modified
+
+- `internal/store/store.go` — customer_configs table + CRUD methods
+- `internal/api/handler.go` — config retrieval endpoint, per-customer auth, `ConfigTemplateProvider` interface
+- `internal/web/server.go` — `/configs/*` routes, `SetTemplateFetcher()`
+- `internal/web/embed.go` — embedded default template
+- `internal/web/templates/dashboard.html` — navigation bar
+- `internal/web/templates/customer.html` — navigation bar
+- `internal/web/templates/style.css` — form, nav, button, credential styles
+- `cmd/hub/main.go` — template fetcher wiring, `TemplateInterval` config
+- `configs/hub.yaml.example` — registry section
