+ The deprecated positional output file argument to `notmuch dump` has
+ been replaced with an `--output` option. The input file positional
+ argument to `notmuch restore` has been replaced with an `--input`
+ option for consistency with dump. These changes simplify the syntax
+ of dump/restore options and make them more consistent with other
+ notmuch commands.
