Analytics Server and Analytics Builder: Filtering in the Analytics Builder can now work with or without the missing value imputation
The distribution query service previously had built in missing value imputation enabled when filtering dataset in the Analytics Builder. This causes non existing data to appear in the filtered result which users may not prefer.
The following enhancements are part of this release:
• Added distribution query services that filters data without missing value imputation. Users have the option to filter the datasets with or without the missing value imputation now.
• A warning message that appears when filtering with missing value imputation has been removed from the Builder.

Analytics Manager: Thing property values do not update properly when the Save button is clicked
When using a Java Edge SDK analysis agent in ThingWorx Composer, if you update a Thing property value and click Save to see the updated alert property values, the updated values may fail to display as expected.

Confidence Model Scoring for Boolean and Categorical Goals
|
|---|
|
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.
