	[Core] Added DeepHub API version 2 for all endpoints, implementing a preview of omlox™ API version 2. If authentication is used, the permission.yaml needs to be updated for the new /v2/ targets to be accessible.
	[Core] Added the possibility to POST entities with a given id (i.e. without DeepHub generating a new id). This is only available for endpoints residing under API version 2 (e.g. /v2/zones).
	[UI Admin] New configuration menu: zones and fences live there now. The current subscription/license information can be found there as well.
	[UI Admin] New URL parameter to pan & zoom directly to trackables and/or location providers and to filter/show only the onces mentioned as parameter
	[UI Admin] The “transformation” button on the first page of the zone creation dialog got removed: it was UX-wise not obvious what it does and typically never used because working with a zone implies the use of a transformation of coordinates.
	[UI Admin] The UI docker image is now based on the nginx-unprivileged base image thus allows to be used in restrictive kubernetes policy environments. The web server serving the UI therefore now runs on port 8080 which has to be taken care of in e.g. docker-compose.yml files orchestrating the DeepHub and its UI container.
Fixes	[Core] Fixed a bug where TrackableMotions could remain when the associated Trackable was deleted.
	[Core] Fixed a bug where circular fences could not be posted.
	[Core] Fixed an issue where under extreme load conditions some events would not be forwarded through the websocket interface.
	[Core] Fixed a bug where stationary trackables were not listed after a restart.
	[Core] Fixed a bug which could lead to database corruption with sqlite3. The database file is therefore migrated to a new version. Furthermore, the database file is renamed to data.dat (previously config.dat). A backup of the database is created for each step before the migration: config.dat.bak and data.dat.v1v2.timestamp.bak.
	[Core] Fixed an issue with temporary files from sqlite for read-only Docker containers. For these, it is required to set the environment variable SQLITE_TMPDIR to a writable folder, e.g., the mounted folder with the sqlite database.
	[UI Admin] Filter toggle button immediately opens up the advanced filter dialog instead of the hard to use “right sidebar”
	[UI Admin] On touchscreen devices, tapping on a trackable or location provider to get detail information as tooltip did not work

	[UI Admin] Fences: Search not working
	Searching for a fence via the search bar did not work.
	[UI Admin] Pressing return key to complete change of a value results in custom properties dialog
	Previously, it was impossible to complete the editing of any field within the “Edit view” of a fence or zone by hitting the “return” key on the keyboard.
	[UI Admin] Selecting a fence on the map is not reflected in left view
	Selecting a fence on the map with the mouse now causes the left-side list of all fences to scroll to the selected fence. Additionally, the entry of the selected fence is prominently highlighted in the left-side list.
	[UI Admin] Reset zoom level not working if no data is in DeepHub®
	Previously, if a user clicked the “reset zoom” control widget while the DeepHub® contained no zones or fences, an error could occur within the browser console and the UI would not appear to react to the mouse click.
	[UI Admin] UI stores entered information even though it was rejected
	After editing an object, such as a trackable, the list of all trackables would still show the altered values. However, this was only a bug with the UI; the correct values were stored in the DeepHub®.
	[UI Admin] Fence creation fails in case properties are involved
	When creating a fence, trying to add properties by clicking on the “Add properties” button would lead to an interrupt of the creation process, leaving the fence in an incomplete state. Additionally, errors were visible in the browser console.

	[Core] Fixed an issue where trackable motions did not get certain values assigned from the related trackable.

1.1.6

Features	[Core] IMPORTANT CHANGE: The /v1/zones API was adapted to the latest version of the omlox™ specification. Most importantly, proximity based positioning systems (RFID or iBeacon) require the position to be defined when creating a zone, while ground control points must not be set. The position was previously optional, which allowed to create invalid proximity zones. For other types of RTLS systems ground control points are still required, and the position is still optional.
	[Core] IMPORTANT CHANGE: The property collision_tolerance in the Trackable object has been renamed to exit_tolerance in the latest version of the specification, aligning property names between omlox™ Fences and omlox™ Trackables. This implementation of the Hub has been updated accordingly and may require to adapt the name of this property for client requests.
	[Core] Added REST endpoints for handling omlox™ proximity events at /v1/providers/proximities and /v1/providers/:provider_id/proximity. Proximity events allow easier integrations of proximity based positioning systems (e.g. RFID or iBeacon). A proximity positioning system simply sends an omlox™ Proximity object and the Hub resolves the proximity information into a location by referring to the position defined for the zone which relates to the proximity positioning system.
	[Core] Added REST endpoints to request trackable motions at /v1/trackables/motions and /v1/trackables/:trackable_id/motion.
	[Core] Added WebSocket pub/sub topic trackable_motions according to the omlox™ motion specification. This topic provides real-time updates for trackable movements, also considering the trackable's shape.
	[Core] Added Hub configuration option persist_locations which enables to persist all location updates to the database. Previous locations will be loaded when the Hub starts. This option is now enabled by default. Please note that persisting locations affects overall performance.
	[Core] Updated several configuration options.
	[Core] Updated parsing the elevation_ref parameter of an omlox™ Location object according to the specification.
Fixes	[Core] Fixed an issue where a wrong crs was displayed in the location object for a certain API request.
	[Core] Fixed an issue where a trackable was not correctly removed from the spatial index after it was deleted.

1.1.4

	[Core] Updated the admin frontend, added new features.
	[Core] Updated trackable and collision API. See the api_draft folder with documentation and examples.
	[Core] Added query parameters to conveniently update and select location and fence objects in various projections (local coordinates related to a zone, GPS and UTM projections supported throughout the API).

1.0.1

Features	[Core] OpenID based authorization and Role Based Access Control (refer to Security Authorization.md)
	[Core] Added admin frontend to /v1/web
	[Core] Flexible server configuration options (refer to Server Configuration.md)
	[Core] Fixed: Provider type was always unknown instead of actual type.
	[Core] Added trackables array to location object. This allows to identify to which trackable(s) a location update belongs to for example for websocket location update subscriptions.
	[Core] Added properties field to trackable object. This allows to add custom information associated to a trackable.
	[Core] Improvements and fixes to the GeoFence engine.

1.0.0

Features	[Core] Support for customizable IoT Sensors data:
	Added „sensors“ property. The content of the sensors data is application defined.
	New API endpoints /providers/$id/sensors (GET/PUT) and /trackables/$id/sensors (GET, returning a data array from sensors of all providers belonging to that trackable)
	[Core] Added properties to allow fine grained event controls to the Fence object:
	timeout: Timeout in milliseconds after which a FenceExit event should be triggered when no location updates are sent anymore. Infinite when 0 or null (default).
	exit_tolerance: The distance tolerance to the geometry of a fence in meters before a fence exit event should be triggered when leaving the fence. Useful to avoid fluctuating entry / exit events due to positioning accuracy at the borders of a fence.
	tolerance_timeout: Timeout in milliseconds after which a position outside of a fence, but still within exit_tolerance distance from the fence, should trigger an exit event when it’s not seeing any position update inside the fence.
	[Core] Added params member to Websocket Subscribe request object to allow for parameters related to websocket subscriptions (e.g. crs and geojson parameters, same as query params available for location and fence REST API).
	[Core] Basic Authentication and Security Support

0.9.7

Features	[Core] Advanced 3D fence events and general improvements to fence event API. Fence events can now also overlap.
	[Core] Added properties to Provider and Fence objects, allowing applications to set generic data.
	[Core] Forward properties with FenceEvent, allowing applications to act on associated events (e.g. easily build a relationship between a MES production step and a fence event).
Fixes	[Core] Fixed an issue when requesting GeoJson objects where the object might be invalid.

0.9.5

Features	[Core] Added Websocket publish / subscribe API /ws/socket for location updates and fence events. Available topics: location_updates, location_updates:geojson, fence_events, fence_events:geojson.
	[Core] Added parameter crs to all location APIs to query location data for a given projection (e.g. EPSG:4326 or local).
	[Core] Extended /trackables API. You can now create a trackable and locate the most recent location(s) of any of it's assigned location providers via /trackables/:trackable_id/location(s)
	[Core] Changed position type in Location object to use a GeoJson Point geometry. This simplifies the API and avoids use of differing geometry types in other parts of the API.
	[Core] Updated /providers API
	[Core] Improved data persistence
	[Core] Added HTTP DELETE method to all API resources to clear current data
	[Core] Added /zones/:zone_id/transform and SimpleTransform object specification to allow easy zone setup workflows (useful for example for RFID zone setup to locate scanners)
	[Core] Added /fences/:fence_id/events API to generate FenceEvents via API instead of location based fence event generation by DeepHub. This may be useful for RFID scanners or general applications where a 3rd party server may generate its own fence events. This allows to use foreign generated fence events with a DeepHub fence to relate fence events to real world places.
	[Core] Added /zones/:zone_id/createfence to allow easy creation from an approximated polygon of an existing zone definition.

0.9.1

Features	[Core] Improved handling of invalid fence geometries and give more detailed error descriptions to a user for invalid geometry data.
Fixes	[Core] Fixed geometry type definition for the fence region in the OAS specification and updated example data accordingly. Also provided more detailed description of Position, GeographicPoint and GeographicPolygon types.
	[Core] Fixed fence_name should be name in the OAS Fence object specification.

0.9.0

Features	[Core] First public release
