[Development] Do we need VS2019 for Qt 6.6?

We’ve been looking into this. I’m convinced now that the data Vladimir was looking at on the server side is the one shown in the “Compiler Information” in the Telemetry view of Qt Creator. This is the compiler Qt Creator was built with though, not the compiler that Qt Creator uses for compiling programs locally! So, all this says is that official Qt Creator releases are still done with MSVC 2019 compiler.

Mystery solved, I guess 😊

In 2022 and 2023, around 24M builds ran on Windows in around 600K unique installations worldwide which had at least 10 builds in this period of time. Not even a single one used MSVC2022. The most widely installed is MSVC2019 v29 followed by v28. Most installations (around 250K) are on Qt 6.2. Qt 5.15 has around 60K installations.

Everyone at my small company has been using Qt Creator on Windows to build our application using the VS2022 tools for a minimum of 2+ months, some of us much longer. I couldn't find the telemetry setting you mentioned, so perhaps we all disabled the feature, though that would be surprising.

We build Qt ourselves (also with MSVC 2022) so if this requires that the Qt be an official build perhaps your statistics are missing us.
