A series of new features and stability fixes, manual improvements, and a few language translations have been added.

The GRASS GIS 7.4.2 release provides more than 50 fixes and improvements with respect to the stable release 7.4.1.

Minor module changes

(see also below for closed bugs)

• G74:db.execute: check return code of db_execute_immediate() also for sql option
• G74:i.colors.enhance: check for not existing maps, see #2984
• G74:i.segment: avoid integer overflow with extremely large regions
• G74:i.segment: fix memory management estimation
• G74:i.segment: input bands must not be NULL or constant
• G74:i.vi: add NDVI keyword
• G74:r.buffer: fix interger overflow
• G74:r.horizon: check if coordinates are within the current region, fixes #3634
• G74:r.import: remove hardcoded memory limit
• G74:r.what: fix if coords are just outside current region
• G74:v.db.addtable: create unique index
• G74:v.distance: use default db connection of current mapset
• G74:v.in.ogr: OGR dsn and GRASS db connections are independent of each other
• G74:v.in.ogr: use column type 'text' when appropriate
• G74:v.out.ogr: do not modify OGR dsn
• G74:v.to.db: add more keywords
• G74:v.to.db: fix fractal dimension index

Improvements in the Graphical User Interface

• attribute table manager fails to start from new mapset, closes #3658
• command prompt - Log files produces empty log files, closes #3657
• G_OPT_DB_WHERE - non-functional 'table' icon in gui, closes #3619
• wxGUI: wx4 doesn't have Image.GetHandlers, fixes #3617
• wxGUI: fix m.nviz.image command building
• wxGUI: use simpler widget for MapsetSelect to avoid wxWidgets bug
• wxGUI/rdigit: fix raster digitizer toolbar on mac

Scripting

• libpython: by default, no error output is produced even though the output in case of failure
• pygrass wrongly reported lines for point vector maps, closes #3549

Library changes

• lib/dbmibase: fix get/set connection parameters, clarify default and current parameters
• libraster: improved error msg if compression is not supported
• Vlib, Vect_merge_lines(): use correct line type in messages

User Manuals - Documentation

• G74:d.vect: explain z height for 3D lines/polygons, see #934
• G74:i.atcorr: +short explanation for input visibility raster
• G74:i.atcorr: update manual for PlanetScope 0f
• G74:r.compress manual: example update to current state of r.compress
• G74:r.compress manual: raster NULL cells are compressed by default
• G74:r.fillnulls manual: example extended with bilinear method
• G74:r.in.gdal manual: Raster Attribute Tables note added
• G74:r.mapcalc manual: fix FCELL/float() precision description
• G74:t.rast.algebra manual: explain ply installation on MS-Windows
• G74:v.category: explain option=report
• G74:v.surf.rst manual: example changed from Spearfish to North Carolina dataset
• G74:v.univar manual: beautify example section
• G74:v.what.vect: distance units are meters for lat-long locations

Portability

• ​Dockerfile: have UTF8 defined
• Dockerfile: 'set ENV SHELL' to avoid /bin/sh fallback in interactive GRASS GIS sessions in docker
• Dockerfile: added ncurses dependency since tput is used in lib/init/grass.py
• Fedora RPM SPEC: fix wxGTK-devel and cairo-devel dependencies
• wingrass: wxpython packages rename to python-wx
• winGRASS: add python-ply as a dependency
• winGRASS: add pip as dependency

New Addons since GRASS 7.4.1

• G7A:d.vect.colhist - Draws the histogram of values in a vector attribute column
• G7A:i.rh - Water in atmosphere: relative humidity, water vapour (saturated, actual)
• G7A:r.accumulate - Calculates weighted flow accumulation, stream networks, and the longest flow path using a flow direction map
• G7A:r.in.pdal - Creates a raster map from LAS LiDAR points using univariate statistics and r.in.xyz
• G7A:r.wateroutlet.lessmem - Creates watershed basins from a drainage direction map
