What’s new in a nutshell

The GRASS GIS 8.3.0 release provides more than 360 changes compared to the 8.2 branch. This new minor release brings in many fixes and improvements in GRASS GIS modules and the graphical user interface (GUI) which now has the single window layout by default. Some of the most relevant changes include: support for parallelization in three raster modules, new options added to several temporal modules, and substantial clean-up of g.extension, the module that allows the installation of add-ons. The GUI also received a lot of attention with many fixes and items reorganised. We have also adopted the Clang format and indented most of the C code accordingly. A lot of effort was put into cleaning up the C/C++ code to fix almost all compiler warnings.

Translations have been moved from Transifex to Weblate, which automatically creates pull requests with the translated chunks. We’d like to thank the translators of all languages for their long term support!

Also, docker images have been updated and moved from the mundialis to the OSGeo organization at https://hub.docker.com/r/osgeo/grass-gis/.

We have carried out quite some work in the GitHub Actions: we added support for “pre-commit” in order to reduce unnecessary runs of the automated checks, there were notable improvements in the code checking section and we have activated renovatebot to automatically maintain GitHub Actions.

Last but not least, we have significantly improved the automated release creation to reduce maintainer workload and we have gained nine new contributors! Welcome all!!
