[Qgis-developer] Release schedule discussion - again

[Mathieu Pellerin]

I really like the idea of making one of the focus of the next dev cycle to
be qt5. Even if 2.14 is still compiled against 2.14 by default, it'd be
great to attempt to reach user experience parity between 2.14 & 2.15 on the
major platforms QGIS is shipped on.

Having faced the need to compiled and used QGIS using qt5 libs less than
two weeks ago to fix an issue in qt4, it's nice to see that things mostly
work, but it did show some fine tuning is needed (cmake logic refinements
to handle qt5 libraries, finding a way to deal with qtwpolar, and in-app
issues like broken keyboard shortcuts etc.).

Maybe a hackfest where every dev work on their area of code against qt5
would be cool to finance? :)
