GRASS 8.4.2 released

What’s new in a nutshell

The GRASS GIS 8.4.2 release provides more than 35 improvements and bug fixes compared to version 8.4.1. The changes span core GIS modules, GUI, Python support, packaging, and build infrastructure — making GRASS more stable, reliable, and polished for day-to-day use.

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.

Highlights

• g.region now correctly respects rows and cols when saving a computational region.
• v.overlay will now remove collapsed (zero-length) lines after snapping.
• A new srtm_percent color table is available, improving visualization workflows.
• The Simple Python Editor now supports scripts without required parameters.
• The GraphicalModeler preserves previously defined “where” option values, improving usability and consistency.
