+# BZOD v0.7.0 — Responsive UI, Theme Support & Build Metadata
+
+Release Date: 2026-08-11
+
+## Highlights
+
+- **Responsive UI**: Admin and user registry panels (URLs and landing pages) now adapt across desktop, laptop, tablet, and mobile viewports. Tables switch to card layouts on smaller screens, and horizontal scrolling issues in registry panels have been resolved.
+
+- **Dark/Light Theme Support**: A dark/light theme toggle has been implemented with theme persistence across sessions and responsive behavior across device sizes.
+
+- **Build Metadata**: The application now exposes its actual Cargo package version and, when available, the Git commit hash. This is powered by `build.rs` (compile-time Git commit extraction) and `src/build_info.rs` (exposing `APP_VERSION` and `GIT_COMMIT` constants). The version is derived from `Cargo.toml` via `env!("CARGO_PKG_VERSION")`, and the Git commit hash falls back gracefully to `"unknown"` when unavailable.
+
+- **Public Landing Page Serving**: Root `/` now serves the public `www/index.html` with runtime file detection and embedded fallback behavior. Public/runtime www assets are supported by the deployment layout.
+
