Major module changes

(see also below for closed bugs)

  • G76:...

Minor module changes

(see also below for closed bugs)

Improvements in the Graphical User Interface

  • wxGUI/dbmgr: don't show db info connection by default, it's just occupying space in the dialog

Python scripting

  • libpython: add tempname() function to grass.script.core, fix #3615
  • libpython array.py: added quiet option to write function
  • libpython db.py: added option in db_table_in_vector to check by default only vectors in current mapset
  • libpython: by default, no error output is produced even though the output in case of failure reads "Process ended with non-zero return code 1. See errors in the (error) output.", change default to cpature and report error output (backport trunk r73238)
  • pygrass: attempt to access data from a closed raster map now rises IndexError
  • pygrass: add Module support to underscore in parameter's name
  • pygrass: Avoid to pass unicode to C functions in mapsets and location
  • pygrass: Category.init expects map name to be provided
  • pygrass: grid avoid to add a mapset if already present in the path
  • pygrass: grid: Fix doctest
  • pygrass: number_of() add support for boundaries and centroids (merge r73394 from trunk)
  • pygrass: Provide better error message when raster row index is out of range; Raise IndexError (instead of fatal exit) when operating on a colsed map. This is a more Pyhtonic way.
  • pygrass: raster PEP8 cleanup
  • pygrass: shortcuts: Fix use of python reserved words
  • pygrass: fix wrongly reports lines for point vector maps, see #3549 (g76: merge r73393 from trunk)
  • python ctypes: add int64 to ctypes_type_map

Projection support

  • Support of PROJ v.5
    • configure: use new PROJ API only with proj-5.1.x or higher, otherwise fall back to old PROJ.4 API

Library changes

  • dbmibase: fix get/set connection parameters, clarify default and current parameters
  • libgis: update to lz4-1.8.2
  • libgis: use G_vasprintf() to avoid buffer overflow
  • libproj: +new GRASS API for coordinate transformation, use new PROJ 5+ API starting with proj-5.1.0 if available
  • libproj: support user-defined PROJ 5+ pipelines
  • libraster: +GRASS virtual raster (VRT)
  • libraster: update documentation for Map type ("raster", "reclass", "GDAL-link", or "virtual")
  • libsegment: + all in memory cache
  • libsegment: do not zero fill, use lseek in Segment_open()
  • libstats: init vars
  • libstats: sum of weights must be DCELL; fix regression t value
  • libogsf: Use framebuffer objects for off-screen GL rendering; Use Core OpenGL (CGL) for the MacOS instead of deprecated 32-bit only AGL (Fix #3600, #2114, #3606)
  • G76:grass-sqlite driver: fix default column length for declared column types
  • Vlib: change topology building messages to verbose messages, use grass_int64 for count of vertices
  • Vlib: fix for self-intersections in Vect_line_intersection2(): snap self-intersection only once
  • Vlib: fix self-intersections in Vect_line_intersection2()
  • Vlib: fix with_z = 0 for Vect_line_check_intersection2() and Vect_line_intersection2(), fixes #3567
  • Vlib: increase buffer to 4096 when copying files (sync to lib/gis/copy_dir.c)
  • Vlib: optimize snapping with box search instead of distance search
  • Vlib: print messages only when needed during topology building
  • Vlib: reduce dynamic fp representation error threshold
  • Vlib, Vect_merge_lines(): use correct line type in messages
  • temporal algebra: Added suffix option for time and granularity based raster map names
  • temporal algebra: Do not create the parsertab file when running the algebra
  • temporal library: eval support for t.info, see #3264
