 - *(help)* "Command" is used as the section heading for subcommands and `COMMAND` for the value name.  To get the old behavior, see  `Command::subcommand_help_heading` and `Arg::subcommand_value_name`
 - *(help)* Whitespace in help output is now trimmed to ensure consistency regardless of how well a template matches the users needs.
+- *(help)* name/version/author are removed by default from help output.  To get the old behavior, see `Command::help_template`.
 - *(env)* Parse `--help` and `--version` like any `ArgAction::SetTrue` flag (#3776)
 - *(derive)* Changed the default for arguments from `parse` to `value_parser`., removing `parse` support
