    v40 v41  
    2121GRASS GIS 7.6 graphical user interface now displays the computational region extent by default in the Map Display window. This simple new feature allows to always visualize such an important basic concept in GRASS GIS and makes it a lot easier for newcomers. Moreover, a new widget has been implemented for commands including an SQL WHERE parameter to ease selection of features/data.

    2626Many fixes were aimed to enhance compatibility with wxPython 4. The data catalog, the graphical modeler and the startup have also received many improvements in this new major GRASS GIS release.

    5151 * G76:r.colors includes inferno, magma and plasma color tables as well as a new flag -d to list available rules with description (e.g. "srtm: color palette for Shuttle Radar Topography Mission elevation [range: -11000 to 8850]")

    5656Many raster modules use the new GRASS GIS API for coordinate transformation and are also ready to use [https://proj4.org/ PROJ v5 API] if available (See ''Library'' changes section below). This was a significant improvement and a great effort implemented during the [https://grasswiki.osgeo.org/wiki/GRASS_Community_Sprint_Bonn_2018 OSGeo Code Sprint 2018] in Bonn.

    122122Among these new extensions there is a set of new addons to import and pre-process Copernicus Sentinel 2 imagery: G7A:i.sentinel.preproc and G7A:i.sentinel.mask. These two modules which add up to the existant G7A:i.sentinel.download and G7A:i.sentinel.import, were contributed by a student under [https://trac.osgeo.org/grass/wiki/GSoC/2018 Google Summer of Code 2018] program. With all these Sentinel related modules GRASS GIS provides now the possibility to create full workflows that include download, import, atmospheric correction and cloud masking of Sentinel 2 imagery. Additional imagery addons include, G7A:i.pysptools.unmix for extracting endmembers and spectral unmixing using [https://pysptools.sourceforge.io/ pysptools] and a set of [https://grass.osgeo.org/grass7/manuals/addons/i.signature.list.html i.signature] tools to list, copy and remove signature files. Moreover, a new set of addons for artificial neural networks was also initially developed, G7A:i.ann.maskrcnn, to perform supervised classification using convolutional neural networks.
