    Description

      This phase marks a critical point where the availability of "C++ 20" support in the toolchain and in the standard libraries are required to compile Qt and compile a Qt-based application. This is basically similar to the requirement for "C++ 17" in Qt 6.0

      The qualitative difference to Phase II (QTBUG-109361) is that here, we "inflict" C++20, inclusive its deprecations, onto the user project.

      This user story links to other issues on Qt Bug Reports which are scheduled for this phase.

      The "Fix Version" field should mark a version that contains all scoped topics, even if some of them have been provided in earlier versions.
       
      The tentative plan is Qt 6.12+
