We are thinking to drop Py2.x support from FireWorks. Currently, FireWorks is being unit tested only on Py3+ and some of the libraries it uses are also Py3+ or are moving in that direction. Thus, it is more a question of when (rather than if) that newer versions of FireWorks will no longer support Py2.x.
This is just a thread to ask - does anyone really need Py2.x in the short term? Or can we go ahead and officially drop 2.x support now?
