2N OS version 2.50.0 for 2N IP Access Control Systems includes the following changes

Precautions to be taken during update to FW version 2.50.x

• Devices no longer emit audible beeps during boot or network state changes by default. If required, this behavior can be enabled under `Hardware > Audio > Startup and Network States Signalization`.
• 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.

New Functions and Improvements

• Support for 2N Electronic Locks is now included as part of the standard firmware release.

Essential Corrections

• 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).
• 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`.
• The `snmpget` function now works correctly on devices using SNMPv3.
• 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.
• Other corrections and fixes.
