A short summary of changes: New features in GRASS 7.8

Releases

Stable Release

  • tbd

Release Candidate 1 (RC1)

Git Source Code

  • Milestone: 7.8.0
  • Release branch created in rXXXXX

Overview of changes

The most important change is the new Python-3 support. Also new PROJ 6 and GDAL 2.5 with substantial changes in the API and CRS handling are supported. A series of new features and stability fixes, manual improvements, and a more language translations have been added. Importantly, the new version is backward compatible with older 7.x releases.

The GRASS GIS 7.8.0 release provides more than XXX fixes and improvements with respect to the stable release 7.6.x.

Breaking news: Python 3 compatibility**

New modules

  • G78:...

Major module changes

(see also below for closed bugs)

  • G78:...

Minor module changes

(see also below for closed bugs)

Start script:

  • G78:grass: stop clearing the terminal upon closing; shorten GRASS prompt; do not require dev pkg to be installed for path grass --config path as well as version and svn_revision. Note that revision is currently broken due to Subversion to Git migration.

Modules:

Improvements in the Graphical User Interface

  • wxGUI data catalog: allow to perform actions on multiple layers (e.g. deleting, moving, reprojection, display, metadata)
  • wxGUI/digitizer: fixes for Python 3
  • wxGUI: add function to LM interface to programmatically change layer
  • wxGUI: add GeoPackage as known raster/vector format
  • wxGUI: fix setting non-ascii display name
  • wxGUI/psmap: wxPython 4 compatibility
  • wxGUI: use g.proj list_codes=EPSG to read EPSG codes

Python scripting

  • all python scripts: change Python shebang to python3 (PR #75, #82)
  • pygrass: fixing doctests (only for Python 3)
  • pygrass.gis: make region importable from grass.pygrass.gis
  • pythonlib: fix encoding

Projection support

  • libproj: code clean-up; PROJ5: EPSG must lowercase epsg, PROJ6+: EPSG must uppercase EPSG

Database support

  • postgres driver: create index if not exists for PG server versions 9.5+

Library changes

  • configure, configure.in: configure with ZSTD by default, can be disabled with --with-zstd=no
  • ctypes: delete lib/python/ctypes/ctypesgencore/parser/lextab.py (#95)- since lextab.py is auto-generated
  • libpython: float_or_dms accept E,W,N,S
  • libraster: add support for GDAL 2.4 on MS Windows
  • libraster: fsync data files before closing, and capture any errors; sync_and_close() null file; no fsync check for corrupt raster data on Windows
  • libsegment: fix for all-in-memory cache
  • libvector: support reserved PostgreSQL keywords as column name by quoting when exporting vector map to PostGIS database; Vect_cidx_find_all() should not allow mixing GV_AREA with other geometries
  • parser: added --json output, useful for REST API output (needed e.g. for ​actinia)
  • Vlib: adjust dynamic floating point representation error for squared distances
  • Vlib: fix fp error in Vect_segment_intersection()

Unit tests / CI

  • testsuite/examples/test_framework_GRASS_GIS_with_NC.sh: major cleanup
  • various modules: test added and respective testsuites cleaned up
  • Travis-CI: enable ccache for faster builds
  • Codecov: Attempt to add Codecov support for automated source code quality checks (​https://codecov.io/gh/OSGeo/grass)

User Manuals - Documentation

  • various manual pages: examples added/updated

Portability

  • Python-3 support implemented across the tree

Docker support
