2N OS version 2.50.1 for 2N IP Access Control Systems includes the following changes

Essential Corrections

Fixed an issue with 2N Electronic Locks that limited the device directory to 2000 users.
Fixed an issue where the ProfileStateChanged block in Automation functions caused an error after reboot.
Fixed an issue where Access Unit 1.0 was unable to boot for an extended period after power loss.
Updated several internal libraries.
Important bug fixes.

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

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.

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.
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.

2N OS version 2.49.1 for 2N IP Access Control Systems includes the following changes

Essential Corrections

Updated an internal library containing critical vulnerabilities.
Fixed a critical issue with DNS which caused the device to, e.g., become unable to re-register to a SIP server after its IP address changes. This also solved other DNS-related issues.
Important bug fixes.

2N OS version 2.49.0 for 2N IP Access Control Systems 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.
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.

New Functions and Improvements

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.
Separate parameters are now available to independently enable and select modes for both License Plate Recognition and Character Trimming.
A firewall has been added the following devices: Answering Units, Access Unit 2.0, and Access Unit M.

Essential Corrections

Updated several internal libraries.
Improved precision of WaveKey-based door unlocking.
Enhanced SMTP reliability.
Syslog now correctly logs initial packets after reboot.
`/api/accesspoint/grantaccess` now activates the configured Door Switch instead of always triggering Switch 1.
Valid credentials are now correctly logged as `valid=true` even when an extender (e.g., RFID) is not set as Door Entry.
Improved access signalization for invalid Access Validity periods.
Auto Provisioning now runs at the configured time, using the correct timezone offset.
QR codes are now transmitted correctly to Genetec Synergis as cards.
Important bug fixes.
