- Fix typo in README
- Replace tab character with spaces and correct wrong indents.
- Bugfix: headers are not sorted by keys when the option is `:all`
- Optimize filtering logic
- Call the formatter middleware manaully to parse env['rack.input'] and set the grape request body early
- Overload the formatter's #before method so we don't parse the input twice
- Wouldn't be an issue if Grape::Endpoint would #use custom middleware after using formatter
