  • Arg<'a, 'b, 'c, 'd, 'e, 'f> => Arg<'a, 'b>
  • ArgMatches<'a, 'b> => ArgMatches<'a>
• Simply Renamed
  • App::arg_group => App::group
  • App::arg_groups => App::groups
  • ArgGroup::add => ArgGroup::arg
  • ArgGroup::add_all => ArgGroup::args
  • ClapError => Error
  • struct field ClapError::error_type => Error::kind
  • ClapResult => Result
  • ClapErrorType => ErrorKind
• Removed Deprecated Functions and Methods

  • InvalidUnicode => InvalidUtf8
  • InvalidArgument => UnknownArgument
• Usage Parser
  • Value names can now be specified inline, i.e. -o, --option <FILE> <FILE2> 'some option which takes two files'
  • There is now a priority of order to determine the name - This is perhaps the biggest breaking change. See the documentation for full details. Prior to this change, the value name took precedence. Ensure your args are using the proper names (i.e. typically the long or short and NOT the value name) throughout the code
• ArgMatches::values_of returns an Values now which implements Iterator (should not break any code)
• crate_version! returns &'static str instead of String
