GRASS GIS 8.3.1 released

GRASS GIS 8.3 GUI with vector map

What’s new in a nutshell

The GRASS GIS 8.3.1 maintenance release provides more than 60 changes compared to 8.3.0. This new patch release brings in important fixes and improvements in GRASS GIS modules and the graphical user interface (GUI) which stabilizes the new single window layout active by default.

Some of the most relevant changes include: fixes for r.watershed which got partially broken in the 8.3.0 release; and a fix for installing addons on MS Windows with g.extension.

Translations continue in Weblate, which automatically creates pull requests with the translated chunks. We’d like to thank the translators of all languages for their ongoing support!
