Overview of changes

The most important change is the new Python-3 support. Also new PROJ 6 and GDAL 2.5 with substantial changes in the API and CRS handling are supported. A series of new features and stability fixes, manual improvements, and a more language translations have been added. Importantly, the new version is backward compatible with older 7.x releases.

The GRASS GIS 7.8.0 release provides more than XXX fixes and improvements with respect to the stable release 7.6.x.
