## What's New
If you're already familiar with `clap` but just want to see some new highlights as of **1.4.3**
If you're already familiar with `clap` but just want to see some new highlights as of **1.4.4**
* `-Lvalue` style options are **now supported**! (i.e. `-L` is the short, and `value` is the value being passed. Equivilant to `-L value`). This can be combined with flag expansion. Example: `-lF2` could be parsed as `-l -F 2` where `-l` is a flag and `-F` is an option that takes a number.
* There is a **new opt-in setting** (`AppSettings::TrailingVarArg`) to allow the final positional argument to be a vararg and have `clap` not interpret the remaining arguments (i.e. useful when final argument should be a list of arguments for another command or process)
* You can now access values from an argument in a group via the group name, instead of having to check each arg name individually to find out which one was used. The same applies for checking if an arg from a group `is_present()`
* You now have the option to **not** `panic!` on invalid unicode. The `*_safe()` family of `get_matches` will return an `Err` with `ClapErrorType::InvalidUnicode`.
* You have the option to get lossy unicode values. By using the `*_lossy()` versions of the `get_matches` family of methods all invalid unicode will be replaced with `U+FFFD` and **not** `panic!` or fail parsing.

- Supports the unix `--` meaning, only positional arguments follow
- Optionally sets value parameters (such as the minimum number of values, the maximum number of values, or the exact number of values)
* **Option Arguments** (i.e. those that take values as options)
- Both short and long versions supported (i.e. `-o value` and `--option value` or `--option=value` respectively)
- Both short and long versions supported (i.e. `-o value` or `-ovalue` and `--option value` or `--option=value` respectively)
- Optionally supports multiple values (i.e. `-o <value> -o <other_value>` or the shorthand `-o <value> <other_value>`)
- Optionally supports Specific Value Sets (See below)
- Optionally supports named values so that the usage/help info appears as `-o <name> <other_name>` etc. for when you require specific multiple values
