2N OS version 3.0.0 for 2N Intercoms includes the following changes

Precautions to be taken during update to FW version 3.0.x

• For security reasons, network settings can no longer be modified using 2N Network Scanner.
• All 2N OS devices (except those on the original platform: IP Vario, IP Force, IP Safety, IP Solo, IP/LTE Verso, IP Base, IP Uni, IP Audio Kit, IP Video Kit, Access Unit, SIP Speaker) can no longer be downgraded below version 2.47.0 after updating.
• Devices no longer accept certificates signed with 1024-bit RSA keys. These certificates are removed during the update and must be replaced with certificates using at least 2048-bit RSA or ECC keys. Services relying on weaker certificates will stop functioning, and a warning will appear next to the certificate selection parameter in the web interface.
• In EAP-TLS mode, 802.1x no longer supports RADIUS certificates containing the `id-kp-clientAuth` Extended Key Usage. If such certificates are used, they will be rejected after the update, resulting in the device being unable to authenticate and connect to the network.

Introducing the MVP of our new graphical interface

• We are excited to deliver the first Minimum Viable Product of our redesigned graphical interface. This initial release brings several impactful improvements that make everyday work smoother and more intuitive. Among the most notable additions are guided wizards, an enhanced search experience, and other usability upgrades aimed at significantly improving overall user interaction.
