as everybody should be aware of by now Python2 will reach end of life by year
end. Qt4 (and PyQt4) have not received any maintenance for quite a few months.
Due to these facts I will start removing Python2 and PyQt4 as a runtime
environment for eric6. Future eric6 versions will require Python 3.5 and Qt
5.9 or newer. Support for Python2 development will remain a bit longer (e.g.
the debugger or the various code checkers).
Now is the time to upgrade if that has not happened yet.
