+## [1.1.0] - 2026-02-03
+
+### Added
+- **PIN Hashing (SHA-256)** 🔐 — PINs now stored as secure salted hashes instead of plain text
+- **Remote Configuration** 📡 — Fetch settings from a JSON URL (polls every 5 min)
+- **Digital Signage Mode** 🖼️ — Auto-rotate through multiple URLs at configurable intervals
+- **Error Handling** — Graceful network error pages with retry button
+- **Loading Indicator** — Progress bar during page loads
+- **CI/CD Pipeline** — Automated testing via Gitea Actions
+
+### Changed
+- Admin settings reorganized into sections: Basic, Remote Config, Signage, Security
+- Triple-tap admin unlock now uses programmatic click handler (more reliable)
+
+### Security
+- PINs stored as `salt:hash` format, auto-upgrades plain text PINs on save
+- PIN changes remain local-only (not exposed via remote config)
+
+### Technical Details
+- **New Classes:** `PinSecurity.kt`, `SignageManager.kt`, `RemoteConfigManager.kt`, `ErrorHandler.kt`, `LoadingProgress.kt`
+- **Unit Tests:** 50+ (added PIN, signage, and error handling tests)
+
+### Remote Config JSON Format
+```json
+{
+  "homepage": "https://example.com",
+  "whitelist": "example.com,other.com",
+  "idle_timeout": "300",
+  "signage_urls": ["https://url1", "https://url2"],
