Thanks for the clarification. I had also just upgraded Qt to 6.8.3 for master, previously using the same Qt 6.5.3 as for 4.4.x builds, so this was the first time I noticed those particular warnings.

It started warning with Qt 6.8.0 The warning level change is also due to 3rd party code, Lemon, where we lower the warning level on MSVC when compiling it.
