[Development] Qt 5.12 beta1 released

[Jani Heikkinen]

Hi!

We have released Qt 5.12 beta1 today, see http://blog.qt.io/blog/2018/10/05/qt-5-12-lts-beta-released/

You can find Qt 5.12 beta1 under 'Preview' node from Online installer. Please take a tour & start testing Qt 5.12 now. As earlier we will release new beta releases regularly until we are ready for final Qt 5.12 release. It is really important to recognize all blockers for the final release now so please make sure all release blockers can be found from RC blocker list (https://bugreports.qt.io/issues/?filter=19961).
