To improve security while importing the Analytics Extensions into the ThingWorx platform, new Import Permission Settings have been added. Before importing the Analytics Extensions (Analytics Builder and Analytics Manager), a minimum set of parameters must be configured in the platform-settings.json file. For more information about these settings, see the Import Permissions Settings section of Import the Extension.

An analysis event that was run as a simulation was not being triggered. This issue has been resolved.

When running a request for Signals, and specifying maxAtATime = 2, Mutual Information (MI), in relation to the goal, is not returned for all field combinations as expected. Instead, individual (one-at-a-time) MI scores are returned for all fields and then are filtered down to the top 25% most relevant fields. Two-at-a-time signals are calculated only for those fields. There is currently no way to modify this filtering behavior.

Analysis agents must be restarted after a ThingWorx server restart. Without restart of the agent, any new simulation jobs will fail to execute.

When a non-time series model is uploaded using the Analytics Server Connector, and all of the properties, including the key field are mapped, a time window event does not work.

When a replay event is executed, the on-screen progress bar does not update as the replay event progresses. The issue is related only to the user interface (UI), and the actual execution of the replay is not affected. As a work around, refresh the browser or navigate to another tab and then return to the Replay tab. The progress bar will update. This UI issue will be resolved in a future release.

The Version Info service currently returns a version number that indicates both the external version and the internal build version, but not a path release version. Possible changes in version information are under consideration for a future enhancement.

When filtering is applied to a list page with multiple pages (such as the Models list page), the filtered results are not aggregated for display on a single page. Instead, the filtered results remain on their original pages and multiple pages must be clicked through to find all the filtered results.

To improve handling of list page displays, a configurable parameter has been added to set the number of table items that can be displayed per page. A more permanent resolution for the filtering with pagination issue will be provided in a future release.

The View Datasets and View Models screens do not load properly in the IE 11 browser for the support Windows operating systems. This issue will be resolved in a future release. To avoid the issue, use another browser, such as Chrome, Firefox, or Safari.

When the Analytics Extension is deployed on the 8.3.1 version of ThingWorx platform, the display of some pop-up windows might look compressed in Analytics Builder and Analytics Manager. In some cases, scroll bars will allow you to view truncated fields. However, the best work around for the issue is to maximize your browser view so that the pop-up windows can display fully. This issue will be resolved in a future release.

ThingWatcher has been discontinued as a standalone SDK in 8.3. However, ThingWatcher functionality is available in the Anomaly Detection features native to the ThingWorx platform. For more information, see Anomaly Detection.

ThingPredictor software media is no longer available for download as of 8.3. However, support will continue for 8.x users until the next major release. To replace ThingPredictor capabilities, an improved set of predictive services is being introduced in 8.3. For more information, see How Predictive Scoring Using the Analytics Server Connector Works.

DataConnect and the Data Analytics Definition are not available as of 8.3. Replacement functionality will be introduced in a future release.
