Future of this package

This package is very useful, thanks a lot for providing it! I would like to use it in a large open-source project ([3D Slicer](https://github.com/Slicer/Slicer)) but I'm not sure if I can rely on it in the long term, due to the followings:

1. It seems that there have been no new tags (and releases on PyPI) for almost two years
2. It is still not a native Python3, but patched using 2to3
3. Large backlog of open issues and 10+ open pull requests

Could somebody provide information about current status and future plans for this package?

I see that there have been some recent commits, so I still have some hope. Thanks in advance!
