I would say that it is no longer actively developed. I believe the last commit was 3-4 years ago, and that the differences from the last release to that commit are not large. I also believe that at least some of the developers are still reachable and could answer questions, however there probably are more active projects that depending on what you are looking for might be a better choice, matplotlib for Python for example.
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:

As far as I know there are no plans for a new release, apologies.
Is it abandoned?
