Qt OPC UA: Reading or writing values of type NodeId results in a NodeId with a different namespace index if the index is not part of the server's namespaces array. For details, see https://qt-project.atlassian.net/browse/QTBUG-150760

Linux

macOS

Windows

6.12.0 MinGW binaries are built with MinGW-w64 GCC 15.1.0. The online installer initially showed a wrong version string in the installer tree node, and the repository package names may indicate version 13.1.0. This is a labelling issue only; the installed binaries are built with 15.1.0.

Android

HarmonyOS

6.12.0 can't debug into qt libs. Workaround: home debug build. For details, see https://qt-project.atlassian.net/browse/QTBUG-151135
