Thank you 👍 .

The build fails due to an unrelated error (PyYAML stopped supporting py34). I'll fix it in another PR.

If you don't mind, I would like to help with the fix. As far as I understand, tox.ini will now contain a section for py34 with fixed pyyaml version (this one), like so:

[testenv:py34]
deps =
    {[testenv]deps}
    PyYAML<5.3

For some reason travis doesn't work in my forked repo, so I can't be sure until I make a PR.

Although I hope you have plans to drop older python versions support.

[k4nar]

Ok, thank you!

I think that adding py34: PyYAML<5.3 to the deps section of [testenv] should work as well. Travis should run once you open a PR.
