Hi (I have not found if that was already reported, apologies if I missed aprevious report on this already): As reported via https://sourceforge.net/p/docutils/bugs/303/ changes to Docutils's, in particular to the get_column_widths() method causes the Kernel documentation failing to build via sphinx. The sphinx log generated is (in my example for the 4.8.15 build in Debian): # Sphinx version: 1.4.9 # Python version: 2.7.13rc1 (CPython) # Docutils version: 0.13.1 release # Jinja2 version: 2.8 # Last messages: # writing output...
