24. Added support for LAN Network/VLAN columns in user tables, showing the network and VLAN where each client resides in Dashboard > Traffic > Clients and Insights > Application Analytics > Users.
25. Added support for managing Pro/Campus devices within Omada Controller, enabling discovery, adoption, offline provisioning, site templates and mixed-mesh deployment, while health metrics, anomaly events and Heat-Map Pro models remain unavailable in Site > Device.
26. Added support for displaying the timestamp and status of the latest GPS fix (manual or automatic) on EAP772-Outdoor in AP Details > Config > General (requires EAP772-Outdoor firmware 6.2).
27. Added support for configuring a NAS-ID in switch 802.1X authentication in Network Config > Authentication > 802.1X (requires switch firmware 6.2).
28. Added support for VLAN assignment when MAC-based authentication is selected in switch 802.1X in Network Config > Authentication > 802.1X (requires switch firmware 6.2).
29. Added support for choosing hybrid mode (802.1X first, MAB on failure), displaying downstream devices on switch ports, and configuring a guest VLAN in Network Config > Authentication > 802.1X (requires switch firmware 6.2).
30. Added support for transparent SSDP forwarding when both IGMP Snooping and unknown-multicast discard are active by introducing the "Flood Known Protocols" option in Network Config > Network Settings > LAN > Multicast Snooping (requires Switch 6.2 firmware).
31. Added support for real-time LACP member-status indication: LAG list now shows green for successfully negotiated, up members and red for failed members, with failure logs sent by the switch and stored in the Controller in Switch Details > Ports > LAG List (requires Switch 6.2 firmware).
32. Added support for in-place toggling between Active and Passive LACP modes without deleting and recreating the LAG; Static LAG mode remains unchanged in Switch Details > Ports > LAG Detail (requires Switch 6.2 firmware).
33. Added support for displaying the last-known uplink device and uplink port columns in the device list, preserving this information even after the device goes offline in Devices > Device List.
34. Added support for configuring multiple DHCP-relay server addresses on a Switch VLAN interface (quantity limited by hardware) in Switch Details > Config > VLAN Interface > DHCP Relay (requires Switch 6.2 firmware).
35. Added support for VLAN-aware topology highlighting: links in the VLAN topology diagram now change color to indicate whether the selected VLAN’s traffic can traverse each connection in Network Config > Network Settings > LAN and Dashboard > Topology.
36. Added support for SDM template integration, allowing administrators to view and modify SDM template options directly within switch device templates in Site Template > Device Template (switch) > Config > General > Others > SDM Template (requires Switch 6.2 firmware; supported models listed).
37. Added support for cloud-based remote access (NAT traversal) that lets administrators reach HTTP/HTTPS services on private-LAN devices through a cloud-connected jump host, available for gateway 6.2 firmware and select switch/AP 6.2 builds in Network Tools > Remote Access and Client Details > Toolbox > Remote Access (Cloud Access must be enabled for Local Controller).

 

Enhancements

 

1. Optimized the Internet page by moving Virtual WAN under Port Config and merging the separate Port Config and Load Balancing submit buttons into a single bottom action in Site > Network Config > Network Settings > Internet.
2. Optimized Load Balancing logic to apply device-side settings when WAN Settings Overrides is disabled and added real-time port-status indicators under each WAN weight field to prevent user confusion in Site > Network Config > Network Settings > Internet > Load Balancing (requires gateway 6.2 firmware).
3. Optimized Portal creation/editing with a rebuilt layout that groups settings more intuitively and exposes additional component-customization options in Network Config > Authentication > Portal.
4. Optimized IP-input fields throughout the UI to accept a copied IP address pasted as a single string.
5. Optimized Cloud Access with a redesigned connection flow that reduces cloud-request latency and improves overall user experience in Settings > Cloud Access.
6. Optimized the DPI Rules Management page by replacing the single QoS toggle with a type selector that lets users choose between ACL and QoS rule types in Site > Network Config > Security > Application Control > Rules Management.
7. Optimized controller security with built-in brute-force protection that locks login attempts after repeated password failures on "managed by other" devices in Controller (available now for AP & Gateway; Switch & OLT support planned for firmware 6.3).
8. Optimized public OpenAPI documentation by completing deprecated-interface descriptions and correcting the categorization of site-template endpoints.

 

Bug Fixed

 

1. Fixed bug where RADIUS Message-Authenticator was not forcibly validated, which could lead to RADIUS protocol security vulnerability (CVE-2024-3596), by adding support for enforcing Message-Authenticator verification when the “Require Message-Authenticator” option is enabled, in Site > Network Config > Profile > RADIUS Profile and Global/MSP > Settings > Server Settings > RADIUS Server.
2. Fixed bug where RADIUS packets containing the Proxy-State attribute did not enforce Message-Authenticator validation, potentially exposing the system to RADIUS protocol security vulnerability (CVE-2024-3596), by adding support for limiting Proxy-State and enforcing Message-Authenticator verification when the “Limit Proxy-State” option is enabled, in Site > Network Config > Profile > RADIUS Profile and Global/MSP > Settings > Server Settings > RADIUS Server.
3. Fixed bug where adding a device via Device Key failed in certain scenarios. This is the main modification to the newly provided pre-release version on Mar 27, 2026.

 

Notes

 

1. Please note that Controllers on different platforms may vary in features, even if their first three digits of the version code are the same. For example, the Linux Controller currently supports Cluster Mode, but the Windows Controller doesn't support it yet.
2. The Omada SDN Controller can only manage specific devices running the supported firmware. Please confirm that your device is compatible with the SDN Controller.
3. Since version 5.14.32, the Omada Software Controller no longer supports upgrading from Controller v4.
4. To strengthen overall security, we recommend upgrading all devices to the latest firmware.
