The Qt Quick Extension Plugin in Qt6 differs from Qt5 in the following ways:

  1. Name: In Qt6, the extension plugin is now called the "QML module" instead of the "Qt Quick Extension Plugin" in Qt5.

  2. Design: The QML modules in Qt6 are designed to be used independently and can provide a wider range of functionality beyond Qt Quick components.

  3. Binary compatibility: Qt5 extension plugins were not binary-compatible, meaning that they had to be recompiled and relinked whenever the Qt version changed. In Qt6, the QML modules are binary-compatible, which allows for smoother transitions between versions of Qt.

  4. Consolidation: Qt6 comes with a reduced number of QML modules that have been consolidated into fewer and more comprehensive modules. This makes it easier for developers to find and use the right modules for their projects.

  5. Improved performance: Qt6 has many performance improvements, including faster startup times for QML applications. This is achieved by optimizing the parsing time of QML code, reducing the amount of memory allocated during parsing, and improving the garbage collection algorithms.
