[New-bugs-announce] [issue37504] 3.8 b2 now requires sphinx2, but only has documented 1.8

[Matthias Klose]

New submission from Matthias Klose <doko at debian.org>:

3.8 b2 now requires sphinx2 (according to SilentGhost on IRC), but only has documented 1.8. I'm aware of issue #36007, the last time that the requirements were bumped.

So again, the dependencies were bumped without documenting, and why do we require the latest sphinx again?

It's difficult to provide the documentation as a Linux distro when you always have to provide the latest build tools.  Please compare that to other projects that are usually fine to build with any doxygen, texinfo, or whatever doc tool.

Any hint where the new dependency was introduced, and probably can be backed out?

The actuall error is:

KeyError: 'cols'
