See also: Versions; Previous version: What's new in QuickOPC 2018.3

Internal version number: 5.55

Key changes:

Targeting

• .NET runtimes: Removed .NET Framework 4.6.2 from the list of supported .NET runtimes (use .NET Framework 4.7 instead).
• Operating Systems: Windows 10 now needs to be Anniversary Update or later.

Technology

• For .NET Standard OPC UA, uses OPC Foundation's OPC UA .Net Standard Library 1.4.354.23.

Component Improvements

• Added a new property SessionTimeoutDebug to the UAClientSessionParameters class. The value of this property determines the requested OPC UA session timeout used when a debugger is attached. The normal SessionTimeout defaults to 1 minute, the SessionTimeoutDebug defaults to 10 minutes, making it easier to prevent expired sessions while debugging with breakpoints.
• Enhanced exception messages in various common error cases, for easier troubleshooting.

Component Refactorings

• In the event pull mechanism, added a maximumCount argument to multiple-result PullXXXX methods. Removed single-result PullXXXX methods from the .NET interfaces, and reimplemented them as extension methods.
