Sourced fromcommander's releases.

v7.0.0

Added

• .enablePositionalOptions() to let program and subcommand reuse same option (#1427)
• .passThroughOptions() to pass options through to other programs without needing-- (#1427)
• .allowExcessArguments(false) to show an error message if there are too many command-arguments on command line for the action handler (#1409)
• .configureOutput() to modify use of stdout and stderr or customise display of errors (#1387)
• use.addHelpText() to add text before or after the built-in help, for just current command or also for all subcommands (#1296)
• enhance Option class (#1331)
  • allow hiding options from help
  • allow restricting option arguments to a list of choices
  • allow setting how default value is shown in help
• .createOption() to support subclassing of automatically created options (like.createCommand()) (#1380)
• refactor the code generating the help into a separate public Help class (#1365)
  • support sorting subcommands and options in help
  • support specifying wrap width (columns)
  • allow subclassing Help class
  • allow configuring Help class without subclassing

Changed

• Breaking: options are stored safely by default, not as properties on the command (#1409)
  • this especially affects accessing options on program, useprogram.opts()
  • revert behaviour with.storeOptionsAsProperties()
• Breaking: action handlers are passed options and command separately (#1409)
• deprecated callback parameter to.help() and.outputHelp() (removed from README) (#1296)
• Breaking: errors now displayed usingprocess.stderr.write() instead ofconsole.error()
• deprecate.on('--help') (removed from README) (#1296)
• initialise the command description to empty string (previously undefined) (#1365)
• document and annotate deprecated routines (#1349)

Fixed

• wrapping bugs in help (#1365)
  • first line of command description was wrapping two characters early
  • pad width calculation was not including help option and help command
  • pad width calculation was including hidden options and commands
• improve backwards compatibility for custom command event listeners (#1403)

Deleted

• Breaking:.passCommandToAction() (#1409)
  • no longer needed as action handler is passed options and command
• Breaking: "extra arguments" parameter to action handler (#1409)
  • if being used to detect excess arguments, there is now an error available by setting.allowExcessArguments(false)

Migration Tips

The biggest change is the parsed option values. Previously the options were stored by default as properties on the command object, and now the options are stored separately.
