[Jani Heikkinen]

Hi all,

We have finally first Qt 5.9.0 beta snapshot available via Qt Online Installer for mac and linux users, windows one coming later today or tomorrow morning. Snapshot is smoke tested & seems to be pretty much OK.
Please download the snaphot (instructions here: https://wiki.qt.io/How_to_get_snapshot_via_online_installer) & take a tour. 
Make sure all beta blockers are listed in https://bugreports.qt.io/issues/?filter=18394. 

br,
Jani
