• 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.

• PTC has recently implemented a new support policy with respect to Identity and Access Management (IAM) solutions. Please see the appropriate eSupport center section for more information.

• See this technical support article for important recommendations regarding the use and update of third-party software for ThingWorx.

• Fixed an issue that was preventing logs from opening after selecting View Logs.

• Fixed an issue that was causing a Flow server to generate extraneous core.* files located in /opt/ThingWorxFlow/modules/ux/.

• Fixed an issue that was causing an error when connecting an http action in ThingWorx Flow.

• Fixed an issue that was preventing the User Deletion Enabled option from working in a directory service.

• Fixed an issue that was causing a JSON to get returned instead of a null/zero if a session property with a number base type of zero was bound.

• Fixed an issue that was preventing a custom service derived from the CreateEquipment service to create value streams for newly-created assets.

• Fixed an issue that was preventing a dynamic panel widget from being resized in run time on an iPad.

• Fixed an issue with the data export widget that was preventing it from working in run time on Android and iOS.

• Fixed an issue that was causing nested infotables (two or three infotable levels deep) to return blank values for the selected nested row.

• Fixed an issue that was preventing the grow ratio of containers from working as expected when used in a collection.

• Fixed an issue that was causing the configure bindings screen for events to show all event bindings, even though they were not set, instead of the actual bindings.

• Fixed an issue with the image web component that was preventing the thumbnail image from displaying.

• Fixed an issue with the shape widget that was causing scrollbars when it was used in the collection widget.

• Added the ValidateFlowSetup service in the workflow subsystems.

• Fixed an issue that was preventing workflows from being edited if they were imported from 8.5 to 9.0.

• The number primitive supports positive and negative infinity along with NaN as legitimate number values. ThingWorx does not prevent the persisting of these values; however when running one of the Query Property History APIs on a value stream, a run time exception is generated if an infinity value would meet the query parameters.

• After PLCs are disconnected for an extended period of time, and then reconnected, a race condition can result. The race condition effects a binding failure with Kepserver which causes the Quality Property Tag values to lose referential integrity and become stale.

• A failure occurs when retrieving data from Windchill after an oAuth token expires during a current valid web session. To make it work again, you must start a new web session by closing the current browser and opening a new one.

• In a high availability cluster with a large Thing model, initial startup times for ThingWorx Foundation nodes are longer than expected.

• The Script log does not list the name of an error or the line in the service where the error occurred.
