The updated documentation site is now live at http://robotpy.readthedocs.io/en/latest/ . It cross-links all of the various RobotPy documentation sites and APIs, which should make it easier to find the information that you’re looking for.
Try it out, give me feedback, make some pull requests or file some issues.
Source is at https://github.com/robotpy/robotpy-docs
Note that the ‘stable’ documentation still contains last year’s site and won’t be upgraded until kickoff.
