After almost 1 year of development the GRASS Development team has released the new stable release GRASS GIS 7.6.0. A big thanks to all developers for their work and dedication!
There is a lot to like, including further improvements to the user experience and new useful additional functionalities to modules. I, for example am curious to try out the new raster map type, the GRASS virtual raster (VRT). This is a virtual mosaic of a list of input raster maps.
But I would say, head over to the overview page where you can read more about the new features in the 7.6 release series: new features in GRASS GIS 7.6. Or update GRASS and check out yourself.
