=== Overview of changes ===

The focus of this release are stability fixes.

Important stability fixes across the tree related to Python 3.

The GRASS GIS 7.8.3 release provides '''more than [https://github.com/OSGeo/grass/compare/releasebranch_7_8@%7B12-11-19%7D...releasebranch_7_8@%7B05-01-20%7D 206 fixes and improvements]''' with respect to the release 7.8.2.

A number of Mac-specific, more or less critical bugs have been fixed. The perhaps more notable improvement is the now working vector digitizer (G78:g.gui.vdigit) and a lot of wxGUI fixes. For details, please see below.
