no longer terminates output with \n

At some point, the developers decided that the default output of the
command line tools would be for consumption by other programs or
scripts-- and any command with the -verbose option would be for human
consumption. As a result, non-verbose command-line program output does
not include a newline. For the -format option, you can insert a
newline with \n but unfortunately you cannot with the compare program
other than returning verbose info.

As a workarround if you want an added newline, you can have it:
compare -format "\n" -metric RMSE rose: rose: NULL
