It used to take about 6 months after x.y was released before most major 
packages were available for x.y.  I hope they come faster now.

For Windows, a few hundred unofficial whls, for both win32 and amd64, 
including for matplotlib, are available for (2.7?, 3.4-) 3.7 from 
https://www.lfd.uci.edu/~gohlke/pythonlibs/, and have been for some 
number of months.
