Breaking Changes from the Previous Release

• In DsExcel v5.0.2 and earlier, in order to create an empty Filter with no condition, user had to create a filter with condition first, and then clear the condition. With v5.0.3 onwards, IRange.AutoFilter and IRange.AutoFilter(Field) method behavior has changed. These methods will create empty filter with no condition in the worksheet. No other code needed to set empty filter condition.
