Designer

• Project upgrade support extended for version 8.1.
  The project upgrade process has been enhanced to allow projects created in version 8.1 to be upgraded seamlessly to newer releases.
• Corrected DLL reference verification in Solution environments.
  The reference verification process has been adjusted to correctly validate DLL availability on the appropriate side of the Solution architecture. While the validation behavior has been corrected, ensuring that assemblies and their dependencies are placed in the correct locations remains the responsibility of the solution configuration.

• LinearGauge: Revised and improved control.

• TrendChart: 

  • Improved TrendChart stability when handling null values.
    The TrendChart rendering logic has been enhanced to better handle scenarios involving null data, preventing excessive logging and improving overall client stability during display rendering.
  • Improved stability when opening Trend layouts via script.
    The layout opening process using @Layout.Trend.Open() has been improved to prevent runtime exceptions, ensuring proper execution of lifecycle methods and more reliable layout initialization and cleanup.
• Trace: Improved @Info.Trace logging during display shutdown. The tracing mechanism has been enhanced to ensure that @Info.Trace calls executed during the display closing lifecycle are properly shown in the trace window, providing more consistent execution visibility.

• HTML5

  • DataGrid
    • Improved column alignment when updating rows.

Protocol Drivers

• PI: User interface improvements for PI configuration.
  The PI configuration interface has been refined by disabling the Use DataPipe option when a PI Server is selected and improving overall text alignment, resulting in a clearer and more consistent user experience.

• ControlLogix: Import improved.

TagProviders

• OPCUA: Improved OPC UA connectivity with certificate validation handling.
  OPC UA connections have been enhanced to ensure more consistent behavior when interacting with servers using untrusted certificates, improving reliability when browsing assets and during runtime execution.

• DataHub: Improved performance.

Runtime

• .Enhanced licensing transparency and evaluation mode handling.

  This release introduces new properties to provide clearer visibility into the current license and evaluation state. The new Info.EvaluationMessage property exposes detailed information about the active license mode, while Device.Channel.<Name>.TotalPoints reports the total number of points configured per device channel.

  RichClient and HTML5Client now display the evaluation reason directly in the interface, improving runtime awareness. Additionally, the system now automatically enters evaluation mode for a 72-hour period when the combined total of device points (Server.SystemMonitor.TotalDevicePoints) and defined assets (Server.SystemMonitor.TotalDefinedAssets) exceeds the licensed model or solution limits.

  These enhancements provide more consistent monitoring and clearer feedback regarding license usage during system operation.

• Enhanced trace logging for TagReference linking.
  The Trace Window now provides clearer warnings when an invalid tag reference is linked, helping users quickly identify and correct configuration issues during design time.

Redundacy

• Improved retentive behavior in redundant environments.
  Retentive value handling has been enhanced to operate more reliably when redundancy is enabled, improving data persistence consistency and stability during concurrent operations.
• Improved redundancy role stability during startup.
  Redundancy handling has been enhanced to prevent unintended role switches between primary and standby nodes during startup, preserving loaded tag values and ensuring more stable behavior regardless of startup order or initial layout configuration.
