=== Overview of changes ===

Since the 6.4.0 release in September 2010 almost 390 source code modifications have been made to the 6.4.x release branch.

'''Between 6.4.0 and the current 6.4.1RC1 more than 390 updates have been applied.'''

==== New modules ====

 * v.in.lines: Creates a lines vector map from an ASCII x,y points file.
 * r.colors.out: Exports the color table associated with a raster map.
 * r.li.pielou: new landscape fragmentation index
 * r.li.reny: new landscape fragmentation index

==== Major module changes ====

 * i.ortho.photo: several resampling methods implemented; artifacts removed; command line support added; photo.* commands renamed to i.photo.*
 * r.proj: fix off by half pixel
 * v.select: added support for new GEOS operators

==== Minor module changes ====

 * d.vect: Ability to take per-feature symbol size and rotation from attribute columns (#600)
 * i.atcorr: AVNIR and IKONOS sensors added (some filter function fixes yet pending)
 * g.mapsets: sort list (-l) output

 * g.transform: add new options to dump coefficients and transform arbitrary points, both fwd and reverse
 * r.distance: output correct precision for different projection types (bugs #654 and #335)
 * r.info: export floats with correct precision (trac #335)

 * r.stats: output correct precision for different projection types (bugs #654 and #335)
 * r.statistics: attempt to fix bug #1090
 * v.db.select: optional file output added
 * v.db.dropcol: recreate the index on the key column of the table
 * v.edit: set up default DB if it doesn't exist
 * v.generalize: do not crash, give out of memory informational messages
 * v.in.ascii: accept D:M:S coords in standard mode 
 * v.in.ogr: faster polygon import, cleaner and smaller output
 * v.info: topology level 1 support added
 * v.mkgrid: optional line support added
 * v.split: do not attempt to read dead line
 * v.surf.rst: z-coordinate and zcol support
 * v.to.db: line azimuth support 
 * v.univar: added optional geometry distances instead of table data 
 * v.vol.rst: new npmax parameter added
 * v.voronoi: much less memory, a bit faster
 * v.what: shell script style output added 

==== Library changes ====

 * cairo driver fixes
 * dglib: graph library cache activated
 * pythonlib: improved
 * PNG driver: Use 64-byte header to ensure frame buffer alignment (bug #937)
 * RST interpolation library: running out of memory problem fix
