 | 2.2.0 | I've added support for formulas, but as this library is based on ClosedXML it has its limitations, as per [Evaluating Formulas](https://github.com/closedxml/closedxml/wiki/Evaluating-Formulas): *Not all formulas are included and you'll probably get a nasty error if the formula isn't supported or if there's an error in the formula. Please test your formulas before going to production.*|
 | 2.3.0 | I've added support for hyperlinks and improved appending to the existing files.|
 | 2.5.0 | I've added Location to ArgumentException Message in ExcelReader. It'll show address of affected cell and the worksheet's name.|
+| 2.6.0 | I've added support for appending starting from given row.|
