In preparation for the future: Qt6

[luzpaz]

Even though v0.20 will still support min version of Qt 5.9 I just wanted to put on the radar that the team is discussing support for Qt6, FWIW

We'll keep an eye on it. Python 3.10 is coming in the August 2022 runtime update so we'll need to be cautious.

main issue with python 3.10 that I can remember was pivy, version 0.6.7 is supposedly compatible with it so that's the first thing to update when 3.10 comes.

[hfiguiere]

pivy 0.6.7 will be in the next build on beta.

[hfiguiere]

we have to revert the pivy update: some tests fail.

[adrianinsaval]

fix for pivy 0.6.7 error: FreeCAD/FreeCAD@b85e9b1fe4 it will be in the 0.20.1 release (no date estimate for it) but feel free to use as a patch meanwhile.

[hfiguiere]

I'll use it only if the runtime update happen before the FreeCAD release, since the next runtime WILL have Python 3.10

[adrianinsaval]

when updating to py3.10 pivy should be updated at least to the recently released 0.6.8: https://github.com/coin3d/pivy/releases/tag/0.6.8 it has an important fix for a crash: coin3d/pivy#98
