[GRASS-user] to move or not move ? grass64 <- ? -> 7.0

[Maris Nartiss]

Hello,
as a (not so active) GRASS developer, I also use 7 for almost all my
daily needs. I agree about all nice things of using 7 previously
stated, still I also must give a fat warning - some code in 7 is not
yet tested enough. There are new bugs present in 7 only too.

Here is (infamous) example of it - output result is shifted by n
cells.[1] Issue was present only in 7 in not so well tested new code.
Bugs do happen and GRASS 7 contains new bugs yet unknown. Anyone is
welcome to use GRASS 7, but remember to check outputs and be ready to
report back issues.

Maris.
