What's new in QuickOPC 2020.3

Internal version number: 5.59

Key changes:

Licensing

Improved the licensing error messages. Besides more precise wording, the typical messages now contain the list of (serial numbers of) licenses that were considered but dropped, together with their "release date covered" field, which is frequently the cause for the license not being recognized.
Added text to License Manager dialog, explaining that licenses with Active status are not necessarily valid, depending on the particular combination of the component and environment status, and that the capabilities of the component itself should be used to check the license validity.

Added larger number of C# examples, showing e.g. how to browse access paths, browse branches, browse leaves, browse properties, browse servers, read item value with specifying server's CLSID, read multiple items "from device", do many reads repeatedly, perform synchronous OPC read, read multiple item values, unsubscribe all or multiple items, write an item (including timestamp and quality), list OPC categories that the server implements, and more.

Added pair of examples UAWcfService1 and UAWcfClient1 (C#): A simple Web service using WCF technology. Provides a GetData method to read a value of an OPC UA variable. Accompanied by a console-based client code.
Added example UAWindowsService1 (C#): A Windows Service that subscribes to variables from the OPC UA sample server, and logs their changes into a file.
Added C# example that shows how to read value of server's NamespaceArray, and display the namespace URIs in it.
Added C# example that shows how to write an ever-incrementing value to an OPC UA variable.

Made clear at multiple places that Product Option licenses (such as Excel Option or StreamInsight Option) require base product license first.

Documentation for all COM objects now consistently contains "Object Creation" section, with syntax for object creation in following languages or tools: C++, Free Pascal, JScript, Object Pascal (Delphi), Perl, PHP, PowerScript, Python, REALbasic (Xojo), Visual Basic (VB 6.), Visual FoxPro, VBA, VBScript, Xbase++.
