Internal version number: 5.83

Key changes:


Technology

  • OPC UA Client-Server parts are now based on OPC Foundation UA-.NETStandard 1.5.376.213.
  • The OpcLabs.MqttNet communication package has been upgraded from MQTTnet and MQTTnet.Extensions.ManagedClient version 4.3.3.952 to 4.3.7.1207.

Packaging

  • Separated low-level OpcLabs.Core and OpcLabs.Core.Forms NuGet packages for reuse. This change is largely invisible to the developer; you keep referencing the same high-level NuGet packages as before, and the new packages get automatically referenced transitively.

Installation and Uninstallation

  • Reorganized the installation components to reflect the choice of products, workloads, development platforms, and features more logically {this change only affects the installation experience if the user choose the custom install).

Component Improvements

OPC UA PubSub

  • The custom connection property "0:MqttTopicPrefix" is interpreted as the <Prefix> part of the topic convention.
  • More relaxed decoding of JSON messages, allowing to process messages from publishers not fully conforming with the OPC UA specification.
