This is a bugfix release in the Freeciv 2.6.x series.

For on overview of what's changed since 2.6.9, see
<https://www.freeciv.org/wiki/NEWS-2.6.10>, or the NEWS-2.6 file in the
source archive.

The archive `freeciv-graphics-materials-2.6.10.tar.bz2` contains
material such as 3D models originally used to prepare Freeciv's
graphics, as a reference for anyone wishing to modify them. It is
distributed separately due to its size, and is not required to build
Freeciv from source.
