2N OS version 2.50.1 for 2N Intercoms includes the following changes
Essential Corrections
Fixed an issue with 2N Electronic Locks that limited the device directory to 2000 users.

2N OS version 2.50.0 for 2N Intercoms includes the following changes
Precautions to be taken during update to FW version 2.50.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.
Due to essential authentication updates for an improved user experience, you must restart the ACS server to restore connectivity for devices upgraded from a version lower than 2.49.0 to version 2.49.0 or higher.
New Functions and Improvements
Reception of `In-Band (Audio)` DTMF is now disabled by default to improve resilience against malicious attacks.
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.
Support for 2N Electronic Locks is now included as part of the standard firmware release.
Essential Corrections
Improved compatibility of outgoing H.264 and H.265 video streams.
Private keys are no longer exposed via `GET /api/mobilekey/config`.
Updated several internal libraries.
Web configuration pages for Automation features now load correctly even when the device is offline (without an active internet connection).
Eliminated occasional audio distortions on IP Uni and IP Audio Kit devices.
Fixed an intermittent issue where audio inputs could become swapped on IP Uni and IP Audio Kit devices.
Devices no longer crash when a user with a limited validity period presents their card, provided the associated RFID reader extension module has `Door` set to `Not used`.
Cached DNS entries for SIP registrars now expire immediately and correctly when the registrar IP address changes, preventing registration failures.
Fixed an issue where devices could lose and reacquire their IP address via DHCP twice after a factory reset and subsequent reboots.
Resolved a device crash that could occur when sending emails using specific SMTP server configurations.
The `snmpget` function now works correctly on devices using SNMPv3.
Devices now correctly process `Too Brief` SIP responses during registration and immediately apply the updated expiry period.
Fixed device crashes caused by specific malformed or non-standard ONVIF requests.
Corrected an issue where video resolution could be incorrectly limited when selecting lower bitrate settings for the H.265 codec.
Added a limited-range mode to the WaveKey opening algorithm to prevent unintended door openings from excessive distance.
PEAP MSCHAPv2 authentication is now fully functional and reliable across all supported models.
Eliminated a condition that could cause SIP registration to become permanently stuck in the unregistered state.
2N OS version 2.50.0 for 2N Intercoms includes the following changes

Important bug fixes.
2N OS version 2.49.0 for 2N Intercoms includes the following changes
Precautions to be taken during update to FW version 2.49.x
Empty device names are no longer supported. Set the name via Services > Web Server > Device Name. If left blank, the device may fail to update.

The administrator account now accepts "root" as a valid username as well.
AXIS Camera Station integration has been significantly improved:
The ACS tab in the web interface is now renamed to AXIS.
AXIS Camera Station integration is now always enabled and accessible using the device's administrator account.
After the initial login to the web interface, the "root" username can also be used for ACS access.
An optional dedicated ACS account is now available.
If ACS was previously enabled with both username and password configured, the dedicated account can still be used.
If your dedicated ACS account used "admin" or "root" as the username and had the same password as the administrator account, it will be merged with the administrator account and you can continue using the same credentials.
If your dedicated ACS account used "admin" or "root" but had a different password from the administrator account, it will be migrated to a temporary administrator account. You can continue using the same credentials, and the account will be merged with the administrator account after its password is updated.
2N IP Utility can now also be used to configure IP settings after the default password has been changed.
The `Enter PIN` button on the IP Style home screen is now blue to help distinguish it from call-related buttons.
Separate parameters are now available to independently enable and select modes for both License Plate Recognition and Character Trimming.

Devices can now generate Certificate Signing Requests (CSR) directly from the web interface under System > Certificates > CSR.
All SIP accounts now support additional backup proxy and registrar servers.
Accessibility features added to IP Style include Blind Assistance Mode and support for quick dial button modules. These can be configured under Calling > Dialing.
The Bluetooth button on IP Style has been enlarged and centered in the navigation bar, which now shares a consistent design across both the standard and custom GUI interfaces.

A firewall has been added to ARTPEC-based devices: IP Style, IP Verso 2.0, IP One, Access Unit QR, and IP Force 2.0.
Essential Corrections
Improved certificate handling.
