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 chooses the custom installation option).
  • The items in Launcher (and Start menu) are now grouped by the product at the first level. All icons related to a product are organized beneath that product. Icons shared by multiple products appear under each such product.

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.

Development Productivity

Visual Studio Integration

  • The Visual Studio extension is now not installed by default. For workloads that require it (Live Binding, or placing components from Visual Toolbox), the user need to either select it specifically during the custom installation, or manually install it afterwards.
