[Lars Knoll]

Hi Jani,

+1 from my side for doing the move to 64bit MinGW in two steps.

Cheers,
Lars

This has been requested several times in mails, blog comments etc. We have discussed this earlier, last time with Qt 5.10 where I proposed that we could replace 32 bit MinGW with 64 bit one. But at that time we weren't ready for that. And it seems 32 bit MinGW package is still quite widely used, see http://lists.qt-project.org/pipermail/development/2017-December/031674.html .

Making this decision now would complete this discussion finally and still give users time to move from 32 bit to 64 bit ones...
