[Development] About the timeline and phases to support C++20 with and in Qt

[Alex Blasche]

Hi,

For Qt 6.8 we continue to work on Phase 1 item https://bugreports.qt.io/browse/QTBUG-109360. In other words we will not  mandate C++20 compilers in Qt 6.8 yet. An LTS release is not the right for such a breaking change anyway. The possible releases for such a drastic change are 6.9 or 6.12 (releases immediately following an LTS release). Note that I am not cofirming those releases but merely point out which type of releases could be potential options.

Considering the track record we have when getting Phase 1 items into the release and considering existing customer concerns I have a hard time believing that 6.9 is a serious option. This is my personal opinion.

Those tasks haven't got any updates recently. What's the status?

I'd like to ask that we go to #3 for 6.8 or 6.9.
