Hi,
You can find a list of changes in option settings and names here:

Thanks, this may be helpful, but is misses small things like the name
being the same but the representation changing. For example, in some v.*
like v.info, the layer parameter in 6* is integer, but 7 wants character.
http://grass.osgeo.org/grass64/manuals/html64_user/v.info.html
http://grass.osgeo.org/grass70/manuals/html70_user/v.info.html
r.info is also changed, with 6* -t having to be re-created for 7 -g then
find the "datatype" in the output.

http://grass.osgeo.org/grass70/manuals/html70_user/r.info.html
Those broke the R code, so spgrass6 has to branch on GRASS 6/7 version in
these cases; others I've seen break example scripts. For script
maintainers, it may be unavoidable that changes have to be made, I agree,
but it can be puzzling.

Yes, the description on:
http://cran.r-project.org/web/packages/spgrass6/index.html
<https://service.gmx.net/de/cgi/derefer?TYPE=3&DEST=http%3A%2F%2Fcran.r-project.org%2Fweb%2Fpackages%2Fspgrass6%2Findex.html>
uses "6+" to signal that subsequent versions are intended to work. Since
the package only uses system(), it will work as long as
--interface-description returns an XML file. Plenty of examples and
scripts stop working because GRASS 6 and 7 modules have different flags
and/or parameter names, but in principle only for that reason. It's hard
for me to check - it would be useful to have a translation table for flag
and parameter names by module where changes have occurred.
Best wishes,
Roger
