@ -3,6 +3,12 @@ Features:
Added the --experimental option that enables use of features that might
change in the future.
Now warning messages are printed by default. If you want to see only
errors and fatals as in previous versions, use option -d0;
option -d4 is equivalent to -dddd and to -d -d -d -d
The number of warnings has been reduced, e.g.removing a non existing
file does in most cases no longer log a warning.
