[Development] HEADS-UP: Branching '5.9.2' from '5.9' started

[Jani Heikkinen]

Hi all,

We have finally soft branched '5.9.2' from '5.9'. So please start using '5.9.2' for new changes targeted to Qt 5.9.2 release. Final downmerge from '5.9' to '5.9.2' will happen Monday 25th September so there should be enough time to finalize ongoing changes in '5.9' and start using '5.9.2' for new ones. 

We are targeting to release Qt 5.9.2 as soon as possible; preferably already during next week so please make sure all blockers are fixed early enough. Qt 5.9.2 blocker list here: https://bugreports.qt.io/issues/?filter=18736 . 

We (release team) will start creating initial change files for Qt 5.9.2 now. So Maintainers: Please finalize those initial ones immediately when available. We need those now really soon to be able to proceed with final release without further delay.

br,
Jani Heikkinen
Release Manager
