Product Support 2N Access Unit M

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.

Essential Corrections

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.

2N OS version 3.0.0 for 2N IP Access Control Systems 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.
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.
If you’re interested in learning how you can support the ongoing development of the new interface and share your feedback with us, please visit the following link: https://www.2n.com/-/media/Files/Web/downloads/Introducing-the-New-2N-Web-Interface

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.

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.
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

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.

New Functions and Improvements

Devices can now generate Certificate Signing Requests (CSR) directly from the web interface under System > Certificates > CSR.
Changing the web interface password now requires entering the current password. As a result, restoring a configuration will no longer change the password. Auto Provisioning can change the password only if the current one is still set to default.
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.
Prevented some certificates from reverting to factory defaults after a software factory reset (without selecting Network Settings), avoiding potential network disconnection.
Removed certain unnecessary syslog messages.
Improved formatting of exported Directory CSV files.
The `UserAuthorized` Automation block now behaves correctly even for failed authorizations.
DNS request lengths can now be up to 255 characters.
RADIUS certificates are now validated properly in EAP-TLS/MSCHAPv2 scenarios.
Commas in the Subject field of the `SendEmail` Automation block no longer cause the subject line to be truncated.
Improved SMTP reliability.
Enhanced handling of large-scale user directory operations.
Important bug fixes.
