GRASS GIS 8.4.1 released

New stable release

The GRASS 8.4.1 release contains more than 80 changes compared to version 8.4.0. This new minor release includes important fixes and improvements to the GRASS tools, libraries and the graphical user interface (GUI), making it more stable and robust for your daily work.

Most importantly, since the 8.4.0 release: location is now project: The Python API, command line, and graphical user interface are using project instead of location for the main component of the data hierarchy while maintaining backward compatibility.

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!GRASS: r.sim.water simulator tool
