Hitting the Qt development list on late Tuesday is word that "the Brisbane Australia office, consisting of the teams working on Qt3D, QtDeclarative, QtMultimedia, QtSensors, and QtSystems modules, as well as the CI/QA team for Qt, will be shut down."
The last day for these Qt tool-kit developers will be on 31 August.
Of course, these developers can continue working on Qt past their Nokia employment if they so choose, but that's not guaranteed. This was the main Qt Australia office.
Meanwhile, Qt 5.0 is going beta in early August.
