Should we support python 2 any longer

stijnvanhoey commented 5 years ago

The shift towards Python 3 is now becoming most general and more and more packages are no longer supporting Python 2. For example, if we want to align with the latest versions of Matplotlib, Python 2 is not an option anymore.

We have different options:

Fix the versions of all dependencies, provide that as install environment and stop further adjustment to make sure the code is following newer versions.
Actively maintain support for Python 2 by adjusting our test-suite and CI and no longer use pyup again
Drop Python 2 and keep niche in alignment to the developments of numpy/matplotlib/... by providing the required patches when needed.

Another reason: Conda on windows no longer provides Python 2.7 packages for rasterio >0.36.

I'm not going to actively remove Python 2 support yet, but I did remove the build on appveyor.

As mentioned in the release notes, version 1.1. is the last version supporting Python 2. For future development, we can ignore Python2.
