2N OS version 3.3.1 for 2N Elevator Systems includes the following changes
Essential Corrections
Updated several internal libraries.
Important bug fixes.
2N OS version 3.3.0 for 2N Elevator Systems includes the following changes
New Functions and Improvements
Firmware management has been consolidated into a new dedicated section: System > Firmware, including firmware auto provisioning settings.
Automatic firmware updates  — firmware can now be updated automatically on device startup or on a configurable periodic schedule.
LTS track support  — devices can now be assigned to a Long-Term Support firmware track.
Auto provisioning for answering units  — firmware auto provisioning is now supported on answering units as well.
Added an option to disable all on-device firmware operations entirely.
Essential Corrections
The `SendHttpRequest` Automation block now correctly encodes unsafe characters using percent encoding. To send the backslash `\` and comma `,` characters, they must be escaped with a preceding backslash `\`, otherwise they are used for escaping and separating parameters, respectively.
For example, to send a command containing this text: `https://127.0.0.1/axis-cgi/io/port.cgi?action=2:\`, the backslash must be escaped with a `\` as follows: `https://127.0.0.1/axis-cgi/io/port.cgi?action=2:\\`. This results in a correctly encoded HTTP command: `https://127.0.0.1/axis-cgi/io/port.cgi?action=2%3A%5C`.
Fixed a time profile-related crash in the user detail view of the new web interface.
Updated several internal libraries.
Important bug fixes.

2N OS version 3.0.2 for 2N Elevator Systems includes the following changes
Essential Corrections
Important bug fixes.
2N OS version 3.0.0 for 2N Elevator 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.
New Functions and Improvements
Reception of `In-Band (Audio)` DTMF is now disabled by default to improve resilience against malicious attacks.
Default values and ranges for `Calling > Alarm Call > Test Alarm` parameters have been updated. `Enable` is now set to TRUE by default, and `Press Duration to Activate` now accepts values from 5 to 60 seconds.
STUN support has been added and can be configured under `Calling > SIP # > Configuration`.
The custom language name defined in the translation file is now displayed in the Display UI instead of the generic "Custom" label.
Essential Corrections
Updated several internal libraries.
Web configuration pages for Automation features now load correctly even when the device is offline (without an active internet connection).
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.
Other corrections and fixes.

2N OS version 2.49.1 for 2N Elevator 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 Elevator 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.

Services relying on weaker certificates will stop functioning, and a warning will appear next to the certificate selection parameter in the web interface.
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.
Lift products can now dial up to 6 destinations per user, increased from the previous limit of 3.
Native integration with Microsoft Teams has been added, allowing bidirectional calling with our devices and enabling door unlocking directly from the Teams client. Configuration is available via Services > Integration > MS Teams.
Essential Corrections
Updated several internal libraries.

2N OS version 2.48.1 for 2N Elevator Systems includes the following changes
Precautions to be taken during update to FW version 2.48.x
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.

Services relying on weaker certificates will stop functioning, and a warning will appear next to the certificate selection parameter in the web interface.
New Functions and Improvements
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.
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.
Essential Corrections
Improved certificate handling.
The `OutputChanged` Automation block in Sentrio Cabin now displays the correct outputs.
The `CallSessionStateChanged` event now triggers correctly for both Checking and Operational Calls.
Prevented some certificates from reverting to factory defaults after a software factory reset (without selecting Network Settings), avoiding potential network disconnection.
SIP unregistration now works correctly with non-RFC-compliant User Agent Servers.
Removed certain unnecessary syslog messages.
Improved formatting of exported Directory CSV files.
SIP authentication passwords can now be up to 255 characters in length.
DNS request lengths can now be up to 255 characters.
Commas in the Subject field of the `SendEmail` Automation block no longer cause the subject line to be truncated.
Fixed device crashes caused by missing Origin fields in SDP offers.
SRTP media is now correctly offered in the ACK response when using delayed SDP negotiation enforced via options.
When SRTP is re-negotiated during a RE-INVITE, the newly established encryption key is now properly applied to outgoing media streams.
Improved stability of the G.729 codec.
Improved SMTP reliability.
Enhanced handling of large-scale user directory operations.
Important bug fixes.
