[Debian-science-sagemath] Sage 7.6.rc1

[Tobias Hansen]

Hi,

I packaged Sage 7.6.rc1. The packages where we are behind are
ipywidgets, jupyter-core, jupyter-notebook and ntl. The build of Sage
7.6.rc1 now gets up to after the docbuild, when it stops because there
are errors in dochtml.log.

The first one is
ImportError: cannot import name ValueWidget
This widget seems to be new in ipywidgets 6.0, so we need that.

The second error is the following. I haven't investigated it in detail
yet. Ximin, is that the error you got when you set threejs as default 3D
viewer?
