See also: Versions; Previous version: What's new in QuickOPC 2018.2

Internal version number: 5.54

Key changes:

Targeting

• .NET runtimes: Removed .NET Framework 4.5.2 from the list of supported .NET runtimes (use .NET Framework 4.6.2 instead).
• .NET runtimes: Removed .NET Framework 4.6 from the list of supported .NET runtimes (use .NET Framework 4.6.2 instead).
• Development tools: Visual Studio 2012 removed from the list of primary development tools. It will likely still work for most tasks, though.

Component Improvements

• Added AllowSha1SignedCertificates property to the UACertificateAcceptancePolicy class. Determines whether certificates signed with SHA-1 message digest algorithm can be accepted.
• Added MinimumCertificateKeySize property to the UACertificateAcceptancePolicy class. Determines the minimum length of the certificate's public key.

Component Refactorings

• Setting an OPC UA certificate acceptance policy specific to an endpoint is no longer supported, as it cannot be reliably implemented due to limitations of the underlying UA stack. You can set the certificate acceptance policy globally.

Instrumentation

• Improved OPC UA logging associated with HTTPS certificate validation.

Tools
