[Releasing] https://bugreports.qt-project.org/browse/QTBUG-35143 :Scene graph threaded render loop deadlocks on X11

[Heikkinen Jani]

Hi all,

Unfortunately we won't get this fixed early enough so that we would have packages today :( And no-one weren't against releasing RC1 without fixing this so we will release RC1 with current content. That's why there isn't any reason to postpone release to Friday. We will release RC1 today if nothing really serious found during these last hours before actual release

Br,
Jani
