rc1 from November is still the latest one on this page, so I presume no others have been created yet. I've noticed a possible issue in it. In past releases, groff's -b option activated backtraces for every warning or error. In rc1, backtraces appear to be on by default, and there is no corresponding option to turn them off. A simple example is the command $ echo '.tm \n(ZZ' | groff -ww Under groff 1.22.4, this emitted to stderr: troff: <standard input>:1: warning: number register 'ZZ' not defined But under rc1 it emits: troff: backtrace: file '<standard input>':1 troff: <standard input>:1: warning: number register 'ZZ' not defined The rc1 documentation still says that -b turns backtraces on, implying they should be off by default. And it lists no new option for turning them off if they are already on.
