[Releasing] First Qt 5.6.3 snapshot available

[Jani Heikkinen]

Hi,

We have finally first Qt 5.6.3 binary snapshot available for testing. Snapshot is available only via online installer and you can do clean installation or add it as a part of existing one. Detailed instructions here: https://wiki.qt.io/How_to_get_snapshot_via_online_installer . Note: snapshot can be found under 'Preview' node from installer ui.

Snapshot is based on https://codereview.qt-project.org/#/c/201968/ . RTA smoke is ran for this snapshot and it seems to be ok for bigger testing so please test the snapshot and report your effort via https://wiki.qt.io/Qt563_release_testing

Please test this snapshot as soon as possible; we need to get understanding where we are with the release. There is really much changes in since 5.6.2 which we released almost a year ago...

Br,
Jani
