Version 3.2.0 - June 19, 2020

What's New

• Adds the option to relocate Items from Brain Management Console and third-party systems via our Web API. In Web API, a new location_request property has been added to Items. This property could be used to request location changes. It's value will be set to null after processing the request.
  In Item Editor, on Item multi select, the button [Relocate] will appear next to [Add to] and [Remove from]. This button will trigger a dialog to appear which can be used to request a location change for all selected Items.
• In Web API, the property custom has been added to subscriptions. Customers can use this at their own discretion to store custom data as required for their application.

Bug Fixes

• [Device Svc] Fixes an issue which accepted non-WebSocket requests. Now all non-WebSocket requests will be rejected.

• [Management Console] Fixes a range and validation issue in Smartspot Bluetooth Pairings dialog.
• [Web API] Fixes an issue with querying custom and meta_data properties in resources. Normally _id suffixes will be stripped from queries as they are type representations. Internally properties are stored without this suffix.
• [Location Svc] Fixes an issue with exception handling which could cause unpredictable shutdown and restart behavior.

Version 3.1.0 - April 2, 2020

What's New

• Adds WebSocket support. From now on WebSocket will be used as our primary data transport between Smartspot and Brain Server. Major highlights are improvements in real-time behavior by a factor 10, reduction in server load and data consumption, especially in idle operations. Smartspot devices starting from firmware version 1.56.0 will automatically use this new method of transportation.
• Implements a backwards compatibility layer for HTTP data transport, so that devices with firmware before version 1.56.0 are still able to stream the data.
• Minor system updates and improvements.

Version 3.0.0 - February 13, 2020

What's New

• This version is the first release since we have changed our internal release and service packaging strategy. Although the version number has jumped from 2.x.x to 3.0.0, no major or breaking changes have been released. This is mainly done for internal purposes, e.g. as a starting point for our new strategy. A summary of our changes: Previously we have been using the version of our Web back-end as the version for Brain Server as a whole. As result of the new strategy, versions of individual services will be selected and packaged. This package will be versioned separately and released as Brain Server.
• Adds BlueTitan BLE Tag support in all our apps and services.
• TLS 1.0 and 1.1 will no longer be supported. Both versions are out-of-date since March 31 2020.
• Minor system updates and improvements.

Bug Fixes

• [Web API] Resolves a typo in the documentation for UntilId.
• [Management Console] Fixes an issue with the range for Max Q factor setting in Smartspot Configuration. The maximum allowed value has been changed from 13 to 15.
• [Location Svc] Fixes an issue that could crash the service after a change in Location configuration.
• [Location Svc] Fixes an issue that could crash the service due to unexpected arguments.
