Features

• Added generic cache invalidation for configuration models. Models can declare cache dependencies using CacheDependency, and the new print\_cache\_dependencies management command can be used to inspect the dependency graph.
• Added notes to configuration templates.
• Added WHOIS lookup and geographic location estimation for devices, including WHOIS details in the admin UI, automatic refresh of stale WHOIS data, estimated-location notifications and warnings, and admin and API filters for estimated locations.
• Added WebSocket support for broadcasting all location updates.
• Added an API endpoint for retrieving indoor device coordinates for a location.
• Added location and floorplan filters to the device list API, allowing searches by location name and filtering by location or floorplan UUID.
• Allowed devices to update their name during re-registration.

Changes

Other changes

• Added VPN subnet and IP address details to the REST API.
• Allowed deleting organizations containing active devices while displaying a warning about the active devices that will be affected.
• Enforced the deactivated device state across OpenWISP Controller. Deactivated devices no longer receive configuration, management, remote command, registration, or automatic template operations, while necessary cleanup and security operations remain enabled.
• Replaced the third-party jsonfield implementation with Django's built-in JSONField #1061, including migration handling for databases upgraded from older OpenWISP Controller versions.
• Changed VPN synchronization errors and recovery events to use generic\_message notifications #1049.
• Improved command status visibility in the admin interface by highlighting statuses with different colors #812.
