Blickfeld-qb2

* Enhancement: The perception algorithm for subtracting the static background has been improved significantly. Separation of foreground and background is now less sensitive to noise or artifacts in the point cloud acquisition.
* Breaking change: The API to configure the static background subtraction has been renamed from `octree` to `static`. Please make sure, that scripts or custom integrations of the Qb2 API are upgraded to the new version.
* Bugfix: Wrong limits were applied for the scan-pattern configuration on initial load of the WebGUI page.
* Bugfix: Allow creation of application keys with higher access level than `AUTHORIZED` via WebGUI.

⚠ Due to security enhancements, downgrading to a previous release is not supported after updating.

Highlights

General

* Enhanced viewer featuring augmented reality, object visualization, map integration, and full-screen mode, etc.
* User Management has been moved out of BETA and is now recommended for all sensors
* Uniform scan pattern implemented with high density and significantly improved distribution of trigger points
* Extended recording functionality now supports additional metadata and raw point cloud frames.
* Overhaul of internal processing for higher performance and reliability
* Improved recovery mode and updated recovery manual

QbProtect

* Object detection and object-based security zones
* ONVIF ALPHA (this implementation is not yet ONVIF conformant, and intrusions are not yet forwarded): Initial support with RTSP video streaming (tested against Senstar and Milestone VMS)
* Implementation of Foveation/Region of Interest scan pattern to improve detection capabilities for fence security use cases

Volume Monitoring

* Enhanced zone and label rendering in the viewer
* Improved sensor setup with enhanced error handling, distinct color representation for sensors, and support for application keys
* Improved stability and health messages

| Viewer with map | Improved sensor setup |

Breaking Changes

* Security: A warning is raised when user management is enabled. Devices without user management are deprecated. Refer to the [migration guide](https://docs.blickfeld.com/qb2/Qb2/operation/authentication.html#_advanced) for assistance.
* WebGUI: The previous "Viewer" has been relocated to "Configuration / Zone Management." The revamped viewer is now read-only and solely intended for visualization purposes.
* Processing: Point-based security zones may exhibit slight behavioral differences due to the application of a voxel filter with a 5cm threshold on the foreground. It is advisable to validate and calibrate the detection system post-upgrade.
* Processing: Existing static backgrounds cannot be migrated to the major version. They will be automatically regenerated on the initial launch.
* Processing: Security zones do no longer operate in parallel with volume zones. They are automatically disabled, and a warning is issued.
* Processing: Security zones now only support a single sensor. If multiple sensors are configured, only the first sensor will be utilized, and a warning will be raised.

* Bugfix: Improved beam control
* Bugfix: Increased auto-stop duration from 1 minute to 5 minutes to avoid too many device restarts

**⚠ The release cannot be downgraded after an update**

* Bugfix: Static IP configuration in WebGUI enforced DNS server
* Bugfix: Support timeout with blickfeld-qb2-method of Blickfeld Flow
* Bugfix: Allow authorized client connections from C++ clients
* Bugfix: Only allow yaw rotation of volume zone
* Bugfix: Reboot button in WebGUI with proper overlay

Highlights
* Introduced User Management BETA; stable release planned for mid of March
* Added [Python Developer](https://docs.blickfeld.com/qb2/Qb2/developer/client_libraries/python.html) guides for [Open3D point cloud fetch](https://docs.blickfeld.com/qb2/Qb2/guides/core_processing_point_cloud_o3d.html), [health monitoring](https://docs.blickfeld.com/qb2/Qb2/guides/diagnostics_health.html), [network configuration](https://docs.blickfeld.com/qb2/Qb2/guides/system_network_configuration.html), and [firmware update](https://docs.blickfeld.com/qb2/Qb2/guides/system_firmware_update.html)
* Added automatic Qb2 alignment deviation detection, which is configured / recalibrated with a sensor setup configuration
* Introduced one-click update button in WebGUI for enhanced convenience
* Logs of the [Blickfeld Flow](https://docs.blickfeld.com/qb2/Qb2/developer/modules/flow.html) are now available via the [Log](https://docs.blickfeld.com/qb2/Qb2/protocol/blickfeld/diagnostics/services/log.html) service, providing comprehensive insights
* Fixed startup of [Blickfeld Flow](https://docs.blickfeld.com/qb2/Qb2/developer/modules/flow.html) with wireless network configuration
* Minor bugfixes and stability updates
