== Raster modules ==

 * r.colors.out: new
 * r.external.out: new
 * r.cost faster by orders of magnitude (10x - 100x)
 * r.walk faster by orders of magnitude (10x - 1000x)

 * r.watershed improved from G6.3 to G6.4 to G6.5 to G7: faster, less memory, floating point DEM support, MFD, clean stream extraction from MFD, segmented mode in G7 faster than in G6 by orders of magnitude (segmented mode in G7 only a bit slower than all-in-ram mode of G6.4)
 * r.gwflow/r3.gwflow: Groundwater flow module update
 * Large File Support (LFS) globally enabled

== Vector modules ==

 * v.krige: new
 * v.in.ogr faster for polygon-import, cleaner output
 * Large File Support (LFS) globally enabled

== Libccmath ==

 * new library for numerical functions

== Libdbmi ==

 * Added support for OFTDate, OFTTime, OFTDateTime

== Libgis ==

 * WPS support implemented in parser
 * Libraster separated out into own library
 * Store metadata in $HOME/.grass7 directory

== Libgmath ==

 * gmath solver updated to use ATLAS blas level 1 algorithms.

== Libraster ==

 * Libraster separated out from libgis, refactored

== Libvector ==

 * Large File Support (LFS) added
 * new spatial index, and spatial index kept in file: faster queries (>10x for large vectors), less memory for opening an existing vector
 * cleaning functions 'break polygons' and 'snap lines' faster, less memory
 * Simple Features API/OGR read/write support (ongoing)

== Documentation ==

 * Use Python to generate HTML docs

== API ==

 * Programmer's manual cleanup: http://download.osgeo.org/grass/grass7_progman/
 * Improved Python API
   * read/write GRASS rasters to/from !NumPy

== Portability ==

 * All shell scripts have been rewritten in Python
 * MS-Windows portability improved, new spawn functions (backported to 6.5 and 6.4)
 * MacOSX portability improved

== Removed modules ==

 * g.ask, g.setproj
 * i.class, i.ortho.photo, i.points, i.vpoints ('''need to be ported'''; old display architecture decommissioned)
 * raster:
   * r.average, r.bilinear, r.median (merged into ...)

   * r.sim.sediment, r.sim.water ('''need to be ported''')
   * r.sum (?)
   * r.terraflow.short (FP version is sufficient)
 * v.digit (new wxPython digitizer)
