UI Localization - The standard forms can now be localized using XML files that map interface element identifiers to strings. Ready-made localization files for French, German, Chinese, Korean, Spanish, Portuguese and Russian are provided in the Localization folder under the component's installation root.
Grouping and Outlining - Rows and columns can now be grouped. To group or ungroup a range of rows or columns, use the Group or Ungroup methods of the RowRange and ColumnRange classes.
New Events - Several new events have been added to the WorkbookView class: ColumnGroupCollapsed, ColumnGroupExpanded, ColumnOutlineLevelToggled, RowGroupCollapsed, RowGroupExpanded, and RowOutlineLevelToggled.
