I cannot anymore obtain any pdf output.

Even with the simple "Apple & Pear" example, that still works fine with 1.3.0, I always get the following error from rinohtype:

rinoh.frontend.sphinx (0.4.2) from /home/nico/.local/lib/python3.8/site-packages/rinoh/frontend/sphinx/init.py
Traceback (most recent call last):
File "/home/nico/.local/lib/python3.8/site-packages/rinoh/frontend/init.py", line 27, in map_node
return cls.mapping[node_name.replace('-', '')](node, **context)
KeyError: 'div'

The simple workaround that I've found is to downgrade to sphinx-tabs 1.3.0.

Ubuntu 20.10
Sphinx version: 3.2.1
Python version: 3.8.6 (CPython)
Docutils version: 0.16 release
Jinja2 version: 2.11.2
