GRASS GIS 8.4.2

The GRASS GIS 8.4.2 release provides more than 35 improvements and fixes with respect to the release 8.4.1.

Highlights

• g.region correctly respects rows and cols when saving a computational region.
• v.overlay removes collapsed (zero-length) lines after snapping.
• A new srtm_percent color table is available.
• The Simple Python Editor supports scripts without required parameters.
• The GraphicalModeler preserves previously defined where option values.

Errata

• Fixed an incorrect radiation conversion in i.evapo.mh that overstated evapotranspiration by using 86.4 instead of the correct factor (0.0864 MJ m⁻² day⁻¹). (#5600)
