1644#### BREAKING CHANGES
1645
1646* **Fewer liftimes! Yay!**
1647 * `App<'a, 'b, 'c, 'd, 'e, 'f>` => `App<'a, 'b>`
1648 * `Arg<'a, 'b, 'c, 'd, 'e, 'f>` => `Arg<'a, 'b>`
1649 * `ArgMatches<'a, 'b>` => `ArgMatches<'a>`
1650* **Simply Renamed**
1651 * `App::arg_group` => `App::group`
1652 * `App::arg_groups` => `App::groups`
1653 * `ArgGroup::add` => `ArgGroup::arg`
1654 * `ArgGroup::add_all` => `ArgGroup::args`
1655 * `ClapError` => `Error`
1656  * struct field `ClapError::error_type` => `Error::kind`
1657 * `ClapResult` => `Result`
1658 * `ClapErrorType` => `ErrorKind`
1659* **Removed Deprecated Functions and Methods**
1660 * `App::subcommands_negate_reqs`
1661 * `App::subcommand_required`
1662 * `App::arg_required_else_help`
1663 * `App::global_version(bool)`
1664 * `App::versionless_subcommands`
1665 * `App::unified_help_messages`
1666 * `App::wait_on_error`
1667 * `App::subcommand_required_else_help`
1668 * `SubCommand::new`
1669 * `App::error_on_no_subcommand`
1670 * `Arg::new`
1671 * `Arg::mutually_excludes`
1672 * `Arg::mutually_excludes_all`
1673 * `Arg::mutually_overrides_with`
1674 * `simple_enum!`
1675* **Renamed Error Variants**
1676 * `InvalidUnicode` => `InvalidUtf8`
1677 * `InvalidArgument` => `UnknownArgument`
1678* **Usage Parser**
1679 * Value names can now be specified inline, i.e. `-o, --option <FILE> <FILE2> 'some option which takes two files'`
1680 * **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**
1681* `ArgMatches::values_of` returns an `Values` now which implements `Iterator` (should not break any code)
1682* `crate_version!` returns `&'static str` instead of `String`
1683* Using the `clap_app!` macro requires compiling with the `unstable` feature because the syntax could change slightly in the future
