[Dune-devel] current support gcc version

[Christoph Grüninger]

Hi Simon,
hi Andreas,

we wanted to keep the required C++ compiler, CMake, and Python 
dependencies as part of the changelog. Then it is also archived for 
older version.

For the current master nobody thought about adding this section to the 
changelog. Once it is there, we might want to link from the website to 
the changelog in our GitLab. This makes it easy to switch the branch and 
get the information for releases.

Kind regards,
Christoph

I think, we wanted to reduce this to 1 or 2 places only. That is why the webpage just refers to another source. This can probably be improved.
