LanGuard 1.25.0

• Unified device-header and interface-table presence displays with compact icons, clearer discovery descriptions, and Likely sleeping labels for inferred sleep. Kept detailed grace-period and other status explanations beside the status while removing redundant bottom-of-page messages.
• Removed repeated device identity and network fields, displayed single-interface addresses and ports once in Network, and limited the Network interfaces table to devices with multiple interfaces.
• Displayed relative interface Last seen times with full timestamp tooltips and automatic minute-by-minute updates.
• Added the latest retained IP, port, or interface configuration change to device details with a History shortcut, including merged-interface events without allowing routine presence events to hide configuration changes.
• Displayed available SNMP agent uptime at the last query and contact information, while hiding empty inventory sections and duplicate system-name and vendor fields.
• Added an Open ports device filter and a clickable dashboard port card with a separate count of devices with open ports. Counted merged interfaces as one logical device and cleared previous filters when navigating from the dashboard.
• Fixed Home Map Attention filtering and room counts to use the server's needs_attention decision, respecting acknowledged alerts and avoiding treating every offline device as requiring attention. Corrected map risk indicators to read the API risk_level field.
• Hid related-link URLs in device view mode, retaining labels and icons with wrapping URL tooltips on hover and keyboard focus. Kept URLs visible during editing.
• Added an independent DHCPv4 lease source integration for read-only dnsmasq, Kea memfile CSV, and ISC DHCP lease files, with admin-only source testing, manual and scheduled synchronization, opt-in Unknown-device creation, and sync summaries and errors.
• Preserved Known-device identity, stronger controller hostnames, newer IP observations, and identity-conflict evidence during DHCP imports. Handled journal updates, releases, expiry, infinite leases, ambiguous MAC records, malformed files, and bounded file reads without inferring Online presence or deleting devices on lease expiry.
• Added Network controllers to integration settings with DHCP source controls, dedicated router and address-book icons, and save support. Ordered integration categories as Network services, Infrastructure, and Network controllers, and documented read-only mounts and remote-file-copy setup.
• Updated Mantine core, hooks, and notifications from 9.7.1 to 9.7.2, Next.js and eslint-config-next from 16.4.0 to 16.4.2, React and React DOM from 19.3.0 to 19.3.1, and Ruff from 0.16.10 to 0.17.1.

Distribution

Docker images are published for linux/amd64 and linux/arm64:

• ghcr.io/hillaliy/languard-backend:1.25.0
• ghcr.io/hillaliy/languard-scheduler:1.25.0
• ghcr.io/hillaliy/languard-frontend:1.25.0

This release updates the web and Docker application. The native macOS application has no source changes; its current installer remains LanGuard 1.24.0 for macOS. No new DMG is included.

The new DHCP integration is disabled by default. To enable it, mount a dedicated lease directory read-only into both backend and scanner containers, then configure the source under Settings > Integrations > Network controllers. See the DHCP setup documentation.

LanGuard 1.24.0

Highlights

• Serialized network scans and DNS integration synchronization across backend and scheduler containers to prevent SQLite lock failures during overlapping writes.
• Refreshed Home Map rooms with selectable room icons, draggable grid positions, adjustable room widths with container-aware content, compact device health summaries, an Attention filter, structured device tooltips, responsive neutral styling, and layout metadata that remains compatible with existing saved maps.
• Displayed the scheduler-owned next network scan time on the dashboard, including live scanning and stale-scheduler states, with automatic interval-change updates.
• Added ordered related links for device manuals, invoices, diagrams, and support pages, with secure editing and inventory import/export support.
• Fixed tablet dashboard and device-list spacing so visitor and archived totals use separate lines and port overflow counts remain fully visible.
• Made failed scan-history badges open accessible, sanitized failure details with stage, code, fingerprint, source, ranges, timing, and recorded scan totals.
• Displayed DNS Activity navigation for configured Technitium DNS Server integrations, using the active provider's console URL and name.
• Replaced the generic Technitium integration icon with the official Technitium DNS Server logo.
• Arranged device-detail actions in compact rows so long device names retain enough space on wide and intermediate screens.
• Reused the desktop device table on landscape tablets by moving navigation into the existing drawer, while preserving the card layout for narrow screens, preventing Gateway badges from truncating, and aligning the menu button with the LanGuard logo.

LanGuard 1.22.0

Docker/web

• Added a read-only Pi-hole v6 integration with application-password authentication, scheduled DNS activity synchronization, DHCP client discovery, protected known-device identity, and shared network-wide and per-device DNS views.
• Moved Docker container inventory to a dedicated responsive page with centralized search, host summaries, clearer port mappings, and navigation that appears only after configuration.
• Improved mobile navigation by moving it into the application header and replacing the full-width navigation bar with a compact page title.
• Applied search, status, network, first-seen, and HomeBox filters to the Roles view while preserving role grouping and list-only bulk actions.
• Kept device actions aligned for long names, displayed hostname and vendor separately, and showed Archived instead of Known for archived devices.
• Removed duplicate global Settings actions and made the activity-retention period save automatically.
• Expanded diagnostics with privacy-safe scan failure details, reliability counts, database settings, and integration workload information.
• Added scheduler tracebacks to container logs for easier production scan diagnosis.
• Updated backend and frontend dependencies, including the security fixes in Next.js 16.3.8.

Architecture and maintenance

This release completes a large behavior-preserving reorganization of the codebase:

• Split the frontend application into focused route, shell, authentication, dashboard, device, Home Map, Settings, integration, notification, and controller modules.
• Split backend views and serializers by product domain with explicit imports and empty package initializers.
• Grouped external integrations in a dedicated package.
• Split network scanning into focused lifecycle, discovery, identity, vendor, port, presence, reconciliation, and orchestration modules.
• Moved backend tests into a dedicated package and split them into focused domain modules while preserving all 444 tests.
• Added Ruff linting to local development and CI and removed the existing unused-import baseline.

Routes, API payloads, database behavior, permissions, and existing user workflows remain compatible.

Update

LanGuard 1.21.0

What changed

• Added read-only local Docker inventory through the scheduler, including container health, networks, published-port correlation, security-change events, and macvlan/ipvlan device linking.
• Added per-device presence expectations with automatic portable-device handling, configurable absence thresholds, and an option to disable prolonged-absence attention.
• Added a responsive archived-device count to the dashboard Devices summary.
• Prevented known devices from needing attention solely because vendor data is missing or a recent scan was missed.
• Fixed open-port guidance overlapping the top navigation and device actions.
