Fixed potential security issues, including items proactively identified by vulnerability scanning software or PTC Quality Assurance testing. Please upgrade as soon as possible to take advantage of these important improvements.

For important recommendations about the use and update of third-party software, see technical support article CS320194.

Previously, the CallTimeout parameter was used to determine how long an agent waited when initiating a connection to a ThingWorx server. A new ConnectionTimeout parameter has been added so the initial connection wait time can be defined separately from other call wait times.

There is currently a dataset size limit of 9 million rows by 30 columns for predictive scoring. When scoring is run on a larger dataset, an error is generated and scoring fails. This issue has been resolved by making a specific buffer maximum flag available in the system-environment-variables.properties file. The maximum size of this flag can be increased. For more information, see Handling Large Datasets.

When Analytics Server is installed with no SSL protections enabled for ZooKeeper, an error is generated. This issue has been resolved so that Analytics Server will not validate for a keystore unless SSL protections for ZooKeeper are enabled during installation.

When adding a data filter, the Equal To filter functionality is not working as expected for certain numeric model parameters, including ROC, RMSE, RMSE Normalized, Person Correlation, and MCC. This issue has been resolved so that all filtering functionality works as expected.

When a predictive scoring job is submitted via a REST API request, the information displayed on the Model list page in Analytics Builder is incorrect. The Number of Records Scored column should reflect the number of data rows submitted in the REST request. Instead, it displays a value of 0.

This issue will be resolved in a future release.

When a filter is applied to the Signals list page and results in no matching jobs, the list is not cleared properly in a Chrome browser and previous results are displayed. This issue will be resolved in a future release.

TA-4972

In ThingWorx Analytics Server 8.5, confidence models for Boolean and categorical goals could be created during training. When these confidence models are scored, the scoring output includes confidence interval information along with the prediction results. In a future release, the confidence interval information will no longer be returned as part of the scoring results for confidence models created in Analytics Server 8.5 with Boolean or categorical goals. In preparation for future upgrades, you should update any application code that is related to scoring these types of models. Ensure that your application code does not rely on the confidence interval results.
