Arg::new
Arg::mutually_excludes

simple_enum!
Renamed Error Variants
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
Using the clap_app! macro requires compiling with the unstable feature because the syntax could change slightly in the future
