Currently,
The file formats have not changed in such a way for this to be a problem. IIRC, the vector indexing protocols have changed in GRASS7, but this is more of a problem going from 6 to 7 than going the other way.
Raster formats currently remain compatible. There has been discussion about changing these, but this has not happened yet.

do not use development versions for production work. If there
is a particular new feature which you just can't live without,
consider putting in a request to have it backported (small things
only)Something to add in the discussion:
I think it is not a question of "is it going to happen that someone curious
opens 6x-mapsets with grass7x for real work, but _when_".And when it happens, will there be (at least) some kind of warning
(mechanism!)? Or/and maybe a major "spread the news" action (in ML's, GRASS-
related feeds)?Thanks, Nikos
