2N OS version 2.46.1 for 2N Intercoms includes the following changes

Precautions to be taken during update to FW version 2.46.x

• Configuration backups from version 2.45.x and higher are incompatible with 2.44.x and lower.
  
• It is necessary to update to version 2.44.0 before updating to a newer firmware version for 2N IP Force and 2N IP Vario with an RFID reader. Direct update from lower versions to version 2.45.0 and higher may cause the RFID reader to stop working.

Essential Corrections

• Important bug fixes

2N OS version 2.46.0 for 2N Intercoms includes the following changes

Precautions to be taken during update to FW version 2.46.x

• Configuration backups from version 2.45.x and higher are incompatible with 2.44.x and lower.
• It is necessary to update to version 2.44.0 before updating to a newer firmware version for 2N IP Force and 2N IP Vario with an RFID reader. Direct update from lower versions to version 2.45.0 and higher may cause the RFID reader to stop working.

Changes Concerning Integration With Other Systems

• Certain VAPIX API calls can no longer be done without authentication.
  
• JSON parameters parsing in /api/dir/create is now order-independent.
• The Event Log no longer includes repeated `SwitchStateChanged` events (and `OutputChanged` events, if configured) when a switch is reactivated while already activated. This prevents unnecessary actions and redundant log entries for a single switch activation session.
  

New Functions and Improvements

• Enhanced integration between FlexiLayout/Custom GUI mode and Automation with two new blocks: `FlexiTrigger` and `FlexiPage`. These blocks make it possible to receive commands directly from the display and to display specific pages, respectively.
  • To utilize the `FlexiTrigger` event in Automation, configure a button with the action `Automation Trigger` in the FlexiLayout builder. Ensure the names of both the `Automation Trigger` action and `FlexiTrigger` event match.
    
  • The `Automation Trigger` action supports up to 5 additional parameters/values, allowing users to leverage a single `FlexiTrigger` block in Automation to perform various actions based on the received parameter(s).
    
• A new field, `Notes`, has been added to User Detail on ARTPEC-based devices, including Style, Verso 2.0, One, and Access Unit QR. This field can store metadata for third-party integration systems or for use with the Automation `Comparator` block.
  
  • The `Comparator` condition enables comparison of user data contained in the `Notes` field (among other parameters) against defined rules. This provides enhanced integration and functionality, extending beyond standard user authentication capabilities.
    
• Other Automation-related changes:
  
  •  Automation blocks are now ordered alphabetically for easier navigation.
    
  • A quick search/filter option is now available in the top left corner to further enhance navigation.
  • The Event Log no longer includes repeated `SwitchStateChanged` events (and `OutputChanged` events, if configured) when a switch is reactivated while already activated. This prevents unnecessary actions and redundant log entries for a single switch activation session.
•  SIPS and SRTP are now enforced for Local Calls after a factory reset. Ensure that all devices in your network operate in the same mode, configured via Calling > Local Calls > Configuration > Network Identification > Local Calls Compatibility Mode.
  
  • For networks with legacy devices, such as 2N Indoor Touch, the Local Calls Compatibility Mode must always be enabled.
• My2N video quality has been significantly enhanced for a dramatically improved user experience.
  
• SIP calls from ARTPEC-based devices now support the H.265 video codec, providing improved video quality and efficiency.
• Zipstream is now enabled by default on ARTPEC-based devices for all streams, optimizing bandwidth and storage usage.
• The display of 2N IP Style can now be completely turned off during idle mode, reducing energy consumption. To enable this feature, set the Hardware > Backlight > In Power Saving Mode Lower To parameter to `Backlight Off`.
• Invalid LPR records from a single session can now be temporarily withheld from the event log for a specified duration, pending the arrival of a valid record from the same session. This setting helps maintain a cleaner and more relevant event log.
• The number of available SIP accounts has been increased from 2 + Local Calls to 4 + Local Calls, enhancing the integration capabilities of 2N OS devices.
  
• A Noise Cancelling feature has been added to ARTPEC-based devices. Enable this feature as needed via Hardware > Audio > Noise Cancelling Enabled
• Added support for SNMPv3, enhancing network management security with authentication and encryption.

Essential Corrections

• Predictable TCP Initial Sequence Numbers Vulnerability fixed.
• 2N IP Style no longer shows the IP address of the ACS server when an ACS client is used to call 2N IP Style.
• Occasional restart when an RTSP stream is sent fixed.
• R bit in the FU header of packetized H.264 I-frames is now correctly set to 0.
• Captured video stream on newer versions of iOS and macOS is now played correctly.
• Dialogs for upload of custom languages now show only .txt and .ini files by default.
• It is now possible to upload video files for slideshow via My2N remote configuration again.
• Devices now update My2N Utility Certificate after restart.
• Special characters in parameters are now properly encoded in the HTTP request URI.
• RTP payload type is now properly updated after RE-INVITE negotiation.
• RTSP client no longer times out after sending GET_PARAMETER request and receiving OK from the server.
• Decoding of special characters in the parameter triggerId of the Automation block HttpTrigger now works correctly.
• Devices now do not crash periodically when a specific auto provisioning URL is configured.
• Lift control IP relays now have a new default value for the IP Address parameter - EMPTY.
• Devices now can enforce SIPS URI scheme when using SIP over TLS.
• It is no longer possible to write values into read only states.
• DHCP Lease Injection attack is no longer possible.
• RFID Module protection against DoS attacks improved.
• Backup SIP registrar configuration now works properly (and independently of SIP proxy settings).
• SID is no longer present in Syslog.
• SIP TLS direct calls now work properly without additional necessary changes in the configuration.
• Important bug fixes.
