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. This issue will be resolved in a future release. As a work around, disable the analysis event and then re-enable it.

TA-8242

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.

Starting with ThingWorx Analytics Server 9.4, PTC will no longer be supporting or shipping the .NET SDK for Analytics Manager.
