Python3 / Qt5
The effort to migrate from Python2 and Qt4 to Python3 and Qt5 is essentially complete and most developers have moved to the Python3 / Qt5 toolchains.

Undoubtedly there are unforeseen bugs and unanticipated breakages that will present themselves during the next development cycle or two, but any existing dependence on Python2 or Qt4 will not be supported moving forward. Note that some developers of certain workbenches have not yet ported to Python3 / Qt5. This may be caused by many things, including a lack of support, time, resources, or broken dependencies that may or may not be easily fixed. Individuals interested in the migration of a particular workbench or tool are encouraged to participate in the forums.
