1282* **Fewer liftimes! Yay!**
1283 * `App<'a, 'b, 'c, 'd, 'e, 'f>` => `App<'a, 'b>`
1284 * `Arg<'a, 'b, 'c, 'd, 'e, 'f>` => `Arg<'a, 'b>`

1312 * `InvalidUnicode` => `InvalidUtf8`
1313 * `InvalidArgument` => `UnknownArgument`
1314* **Usage Parser**
1315 * Value names can now be specified inline, i.e. `-o, --option <FILE> <FILE2> 'some option which takes two files'`
1316 * **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**
1317* `ArgMatches::values_of` returns an `Values` now which implements `Iterator` (should not break any code)
1318* `crate_version!` returns `&'static str` instead of `String`
1319* Using the `clap_app!` macro requires compiling with the `unstable` feature because the syntax could change slightly in the future
