Version 8.1.0 Release Notes
The following feature enhancements and bug fixes exist in ThingWorx 8.1.0:
Enhancements
Platform
Metrics Reporting is enabled by default, which allows usage, performance, and diagnostics data to be sent to a PTC server daily. For more information about this setting, see Platform Subsystem.
You can add and configure Notifications in New Composer. For more information, see Adding Notifications.
License files are now instance specific. For more information, see 8.1 Licensing.
Security for application keys has been enhanced. The default expiration date has been changed to 24 hours if it is not explicitly set. For more information, see Application Keys.
Additional capability has been added to New Composer. For more information, refer to the ThingWorx Community blog.
Improvements to anomaly detection accuracy have been added. As a result, data collection restart is no longer necessary after a long gap and the H2 database that installs with the Training Microservice is stored in memory, not as a persisted file. For more information, see Anomaly Detection.
You can now load configuration/project files from KEPServerEX instances. For more information, see Industrial Connections File Transfer.
