I have created beta2: http://mpa.itc.it/radim/grass-5.7.0beta2.tar.gz All bugs found (except nviz/v.digit on Cygwin) hopefully fixed. This is mixed with 5.3 HEAD from CVS (even if I don't know why 5.3.0 should not work). Radim PS: I have seen new features submitted to 5.3 HEAD after 5.3.0, why that?
