Yes, the coverage and the travis error are not related to this issue.

I don't know if it is necessary to bump the version, but @jtemporal can tell you.

[marius92mc]

Yeah, I also think it is not needed to bump the version.

[giovanisleite]

Yeah we are trying to have a at least a minor bump version for any change in this project. :)

Actually, the readme/documentation is part of the project, so.. i think it is

[marius92mc]

Alright, @giovanisleite, I bumped the version.

Regarding the version bump issue, it's written in the README.md:

Always suggest a version bump.

Always. Because every new code merged into master triggers the CI. And then the CI triggers a new release to PyPI. And this would ruin the whole project (omg I'm so dramatic…) hahaha… anyway, no, that's not a big big problem. But it's important to understand that not bumping the version will break something, and it's also important to understand why it breaks something.

So unless you add [skip ci] to your commit message, yes, bumping version is required ; )
