How to contribute to GRASS GIS development: Guidance for new developers in the GRASS GIS Project.
Please help us testing the Python3 support in the yet unreleased GRASS GIS trunk (i.e., version “grass77” which will be released as “grass78” in the near future).
Why Python 3?
Python 2 is end-of-life (EOL); the current Python 2.7 will retire in 11 months from today (see https://pythonclock.org). We want to follow the “Moving to require Python 3” and complete the change to Python 3. And we need a broader community testing.
Download and test!
Packages are available at time:
- winGRASS GIS 7.7svn daily builds with Python 3, available as standalone installers or in OSGeo4W (announcement)
- docker image: https://hub.docker.com/r/mundialis/grass-gis7-trunk/
- … more following soon
Instructions for testing
- Use grass77 :-)
- https://trac.osgeo.org/grass/wiki/Python3Support#Howtotest
Problems found? Please report them to us
Problems and bugs can be reported in the GRASS GIS trac. Code changes are welcome!
Thanks for testing grass77!
We are pleased to announce the GRASS GIS 7.4.2 release
What’s new in a nutshell
After a bit more than four months of development the new update release GRASS GIS 7.4.2 is available. It provides more than 50 stability fixes and improvements compared to the previous stable version 7.4.1. An overview of the new features in the 7.4 release series is available at New Features in GRASS GIS 7.4.
Efforts have concentrated on making the user experience even better, providing many small, but useful additional functionalities to modules and further improving the graphical user interface. Segmentation now support extremely large raster maps. Dockerfile and Windows support received updates. Also the manual was improved. For a detailed overview, see the list of new features. As a stable release series, 7.4.x enjoys long-term support.

About GRASS GIS
The Geographic Resources Analysis Support System (https://grass.osgeo.org/), commonly referred to as GRASS GIS, is an Open Source Geographic Information System providing powerful raster, vector and geospatial processing capabilities in a single integrated software suite. GRASS GIS includes tools for spatial modeling, visualization of raster and vector data, management and analysis of geospatial data, and the processing of satellite and aerial imagery. It also provides the capability to produce sophisticated presentation graphics and hardcopy maps. GRASS GIS has been translated into about twenty languages and supports a huge array of data formats. It can be used either as a stand-alone application or as backend for other software packages such as QGIS and R geostatistics. It is distributed freely under the terms of the GNU General Public License (GPL). GRASS GIS is a founding member of the Open Source Geospatial Foundation (OSGeo).

An initial announcement has been drafted at
https://trac.osgeo.org/grass
Key fixes include improved portability for MS-Windows (native support), several module fixes, and especially the introduction of a new, Python based portable graphical user interface which includes a new vector digitizer.
About GRASS GIS:
Commonly referred to as GRASS, this is a Geographic Information System (GIS) used for geospatial data management and analysis, image processing, graphics/maps production, spatial modeling, and visualization. GRASS is currently used in academic and commercial settings around the world, as well as by many governmental agencies and environmental consulting companies. GRASS is official project of the Open Source Geospatial Foundation.

Frank Warmerdam has published the new FWTools 1.1.0 binaries for linux and win32. FWTools includes OpenEV, GDAL, MapServer, PROJ.4 and OGDI as well as some supporting components. Basic changes are in the Linux version which now includes the addition of PostgreSQL support in OGR, and SOS Server support in MapServer. This release also includes the new, experimental, PDS (Planetary Data) format support. Download from:
https://www.gdal.org/dl/fwtools/FWTools110.exe

Today PyWPS 1.0.0 has been released by Jachym Cepicky. PyWPS (Python Web Processing Service) implements the OGC Web Processing Service (WPS) standard in Python programming language. It has been written with native support for GRASS GIS which allows for accessing GRASS modules via Web. Processes can be run asynchronously. By default, GRASS GIS is supported, other tools (R, GDAL/OGR, PROJ.4, …) can be configured, too.
A first demo application can be seen here: WUIW – a PyWPS AJAX Web Interface.
After an extra round of hacking, the new SWIG based new GRASS 6.3 Python interface starts work within a GRASS session. We can now call GRASS C functionality in Python scripts. Via libera for GRASS as GIS backbone for other software packages!
