3.4.10 final: March 18, 2019

the last release was 3/18/2019.
I think it's better to wait for a bit longer before dropping it.

@yliaog can this be moved forward. It's not a good service for the community to support python3.4.

[yliaog]

@micw523 what do you think?

[micw523]

@yliaog It's probably fine. I see Matplotlib has already dropped Python 3.4.
