 #### Features
 
-* **Help text auto wraps and aligns at term width!** - Long help strings will now properly wrap and align to term width on Linux and OSX (and presumably Unix too). This can be turned off as well.
-* **Can customize the order of opts, flags, and subcommands in help messages**  - Instead of using the default alphabetical order, you can now re-arange the order of your args and subcommands in help message. This helps to emphasize more popular or important options.

  * **Can auto-derive the order from declaration order** - Have a bunch of args or subcommmands to re-order? You can now just derive the order from the declaration order!
 * **Help subcommand now accepts other subcommands as arguments!** - Similar to other CLI precedents, the `help` subcommand can now accept other subcommands as arguments to display their help message. i.e. `$ myprog help mysubcmd` (*Note* these can even be nested heavily such as `$ myprog help subcmd1 subcmd2 subcmd3` etc.)

 * **Colorized Errors (Non Windows OS only)**: Error message are printed in in colored text (this feature can optionally be disabled, see 'Optional Dependencies / Features').
 * **Global Arguments**: Arguments can optionally be defined once, and be available to all child subcommands.
 * **Custom Validations**: You can define a function to use as a validator of argument values. Imagine defining a function to validate IP addresses, or fail parsing upon error. This means your application logic can be solely focused on *using* values.
-* **POSIX Compatible Conflicts** - In POSIX args can be conflicting, but not fail parsing because whichever arg comes *last* "wins" to to speak. This allows things such as aliases (i.e. `alias ls='ls -l'` but then using `ls -C` in your terminal which ends up passing `ls -l -C` as the final arguments. Since `-l` and `-C` aren't compatible, this effectively runs `ls -C` in `clap` if you choose...`clap` also supports hard conflicts that fail parsing).
