Release Notes

If you are updating from version 3.0.0, the new web interface cannot download firmware from the update server. Update the device using the old web interface or manually upload a newer firmware file.

Fixed an issue that prevented downloading a new firmware from the update server via the new web interface. As a workaround when updating from version 3.0.0, use the old web interface or manually upload a newer firmware file to the device.
Important bug fixes.

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.

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.
Because this is an MVP, some features are still in development. We will continue to refine, expand, and optimize the interface over the coming updates to ensure it reaches its full potential as quickly as possible.

Reception of `In-Band (Audio)` DTMF is now disabled by default to improve resilience against malicious attacks.
Added support for Blind Assistance Mode during incoming calls. In this mode, all controls—both physical buttons and the display—perform identical actions. A short press answers an incoming call or ends an active call, while a long press unlocks the door once the call is connected. This mode is intended for visually impaired users and should not be used together with Screen Lock.
STUN support has been added and can be configured under `Calling > SIP # > Configuration`.
Added support for the Japanese language in the display UI of Answering Units and IP Style.
The custom language name defined in the translation file is now displayed in the Display UI instead of the generic "Custom" label.

Updated several internal libraries.
Cached DNS entries for SIP registrars now expire immediately and correctly when the registrar IP address changes, preventing registration failures.
A voicemail message is no longer played after a successful door unlock if the call was not answered.
Devices now correctly process `Too Brief` SIP responses during registration and immediately apply the updated expiry period.
Eliminated a condition that could cause SIP registration to become permanently stuck in the unregistered state.
Other corrections and fixes.
