   === Feature 4
   
  -The version `1.11` introduces a new annotation called `ExcelCellName` so that we can read the values by column names directly.
  +Using `ExcelCellName`, we can read the values by column names directly.

  === Feature 10
  
  Poiji 2.7.0 introduced the Option `namedHeaderMandatory`. If set to true, Poiji will check that all field annotated with `@ExcelCellName` must have a corresponding column in the Excel sheet. If any column is missing a `HeaderMissingException` will be thrown.

  1. Add `options`, if your excel is xlsx file.
  
  === Feature 15
  
  You can create your own formatting implementation without relying on the default Poiji formatting configuration using the `Formatting` interface.
  
  [source,java]
  ----
  public class MyFormatting implements Formatting {
      @Override
      public String transform(PoijiOptions options, String value) {
          return value.toUpperCase().trim(); <1>
      }
  }
  
  public class Person {
  
      @ExcelCellName("ID")
      protected String employeeId;
  
      @ExcelCellName("NAME")
      protected String name;
  
      @ExcelCellName("SURNAME")
      protected String surname;
  
  }
  ----
  <1> Suppose that all the header names of an excel file have different formatting. Using custom formatting, we are able to look at headers with a custom format. All the headers will be uppercase and don't have white spaces before and after.
  
  Then you can add your custom implementation with the `withFormatting` method:
  
  [source,java]
  ----
  PoijiOptions options = PoijiOptions.PoijiOptionsBuilder.settings()
                  .withFormatting(new MyFormatting())
                  .build();
  List<Person> people = Poiji.fromExcel(excel, Person.class, options);
  ----
  
  === Feature 16
  
  Poiji accepts excel records via Poi Sheet object as well:
  
  ----
  File file = new File("/temp/file.xlsx");
  FileInputStream fileInputStream = new FileInputStream(file);
  Workbook workbook = new XSSFWorkbook(fileInputStream);
  Sheet sheet = workbook.getSheetAt(0);
  
  List<Model> result = Poiji.fromExcel(sheet, Model.class);
