    4343=== General modules ===
    4444
    45 When a new location is created from vector data, G7:g.proj uses the default region s=0 n=1 w=0 e=1 res=1 to avoid potentially invalid region settings (r71491).

    4747=== Raster modules ===
    4848
    49 A new module, G7:r.geomorphon, to calculate geomorphons (terrain forms) and associated geometry using machine vision approach has been integrated (moved from Add-ons) into the core functionalities of GRASS GIS. A very nice addition to G7:r.out.gdal is the possibility to create overviews which enhances the compatibility with other GIS software packages.

    … …  
    105105     and to avoid a rare segfault when opening a GRASS database driver
    106106   * the code has been restructured to make it a bit less unreadable and to fix the logic of steps (e.g. check output only if output is created)

    112112=== Imagery modules ===
    113113
    114 G7:i.atcorr now includes support for the atmospheric correction of 7 new satellite images: Pleiades1a, Pleiades1b, Spot6, Spot7, Sentinel-2A, Rapideye, Worldview3 and mod09GA QA definitions was added to G7:i.modis.qc. In addition to the already existent region growing algorithms, G7:i.segment now also includes mean shift.

    116116=== Temporal GIS modules ===
    117117
    118 The main change in the temporal framework is the introduction of spatial topological operators to the temporal algebra in G7:t.rast.algebra. Moreover, the quantile method has been added to G7:t.rast.series. On the other hand, G7:t.rast.what now has a new flag -v that returns the category for vector points map and a bug in NULL values was fixed, so null value definitions are now passed to G7:r.what correctly. G7:t.rast.export has now support for GDAL options to support GeoTiff compression.

    120120=== Scripting ===
    121121
    122122A new class has been implemented in PyGRASS,
    123 [https://grass.osgeo.org/grass73/manuals/libpython/pygrass.modules.interface.html?highlight=multimodule#pygrass.modules.interface.module.MultiModule MultiModule], which enables temporary region environment for multi module runs. This class allows to put multiple modules into the parallel module queue, for example coupled G7:g.region and G7:r.mapcalc calls, that must be run in a specific order but many of these combined calls should run in parallel.
