### **Firmware version 3.3.0 for AXIS Network Answering Units includes the following changes**

#### **New Functions and Improvements**

* Added HTTP API support.
  * The doorbell can now be triggered remotely via `POST /api/io/doorbell`.
* 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.
* Revamped HTTP commands: Action Buttons now replace the previous HTTP commands-only setup and support three preset types:
  * Each of these can be created and assigned to buttons across the device, including **Home Screen**, **In-Call View**, **External Camera View**, and **Control Center**.
    * **HTTP commands**: Send direct requests to external systems with one tap.
    * **System events**: Record externally provided events to the local Event Log when tapped.
    * **User events**: Trigger custom local events and record them to the Event Log.
  * System and User events do not send outbound commands directly. Instead, they write events to the device Event Log, which third-party systems can monitor through the HTTP API to trigger actions (for example, elevator calls or lighting control).

#### **Essential Corrections**

* Fixed a time profile-related crash in the user detail view of the new web interface.
* Updated several internal libraries.
* Important bug fixes.
