Prosys OPC UA SDK for Java 4.0.0 released

25.03.2019


We have released a new major version of the Prosys OPC UA SDK for Java (formerly known as Prosys OPC UA Java SDK).

The SDK version 4 is based on the OPC UA specification version 1.04. The 4.0.0 release adds support for the most important features, such as new security policies, information models and reverse connections. Other functionality specified in OPC UA 1.04 will be added later on.

Another major change is that the OPC UA Stack is now integrated as part of the SDK.

All users are encouraged to migrate to this new release, although the projects that depend on the OPC UA SDK need to be modified slightly. To help you with the transition, we have prepared a Migration Guide that lists the required changes to your applications in detail.

We are proud to be able to provide this big release that will pave the way to reliable OPC UA applications for future needs.
